## Installation
If you already use [zsh-syntax-highlighting](https://github.com/zsh-users/zsh-syntax-highlighting) plugin, then make sure to be loaded **before** zsh-autosuggestions.
Note: _.zshrc_ is a file that contains user-specific ZSH configuration.
ZSH assumes this file in your home directory (i.e. `~/.zshrc`), but the location can be changed using `ZDOTDIR` variable.
### Using zgen
[Zgen](https://github.com/tarjoilija/zgen) is a simple and fast plugin manager for ZSH.
If you don’t use zgen, then use instructions for the manual installation.
1. Load `tarruda/zsh-autosuggestions` and `zsh-users/zsh-syntax-highlighting` using zgen in your .zshrc file, for example:
```sh
if ! zgen saved; then
echo "Creating a zgen save"
zgen load zsh-users/zsh-syntax-highlighting
# autosuggestions should be loaded last
zgen load tarruda/zsh-autosuggestions
zgen save
fi
```
2. Enable zsh-autosuggestions; copy the following snippet and put it after the zgen config section in your .zshrc file:
```sh
# Enable autosuggestions automatically.
zle-line-init() {
zle autosuggest-start
}
zle -N zle-line-init
```
3. Run `zgen reset` and reopen your terminal.
### Manually
1. Clone this repository to `~/.zsh/zsh-autosuggestions` (or anywhere else):
1. Clone this repository somewhere on your machine. This guide will assume `~/.zsh/zsh-autosuggestions`.
```sh
git clone git://github.com/tarruda/zsh-autosuggestions ~/.zsh/zsh-autosuggestions
```
2. Clone zsh-syntax-highlighting repository to `~/.zsh/zsh-syntax-highlighting` (or anywhere else):
2. Add the following to your `.zshrc`:
```sh
git clone git://github.com/zsh-users/zsh-syntax-highlighting ~/.zsh/zsh-syntax-highlighting
source ~/.zsh/zsh-autosuggestions/dist/autosuggestions.zsh
autosuggest_start
```
3. Load and enable autosuggestions; copy the following snippet and put it to your .zshrc file:
```sh
# Load zsh-syntax-highlighting.
source ~/.zsh/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
# Load zsh-autosuggestions.
source ~/.zsh/zsh-autosuggestions/autosuggestions.zsh
# Enable autosuggestions automatically.
zle-line-init() {
zle autosuggest-start
}
zle -N zle-line-init
```
4. Reopen your terminal.
**Note:** If you're using other zle plugins like `zsh-syntax-highlighting` or `zsh-history-substring-search`, check out the [section on compatibility](#compatibility-with-other-zle-plugins) below.
## Uninstallation
## Usage
Just remove the config lines from .zshrc that you’ve added during “installation.”
If you don’t use zgen, then also delete `~/.zsh/zsh-autosuggestions` and `~/.zsh/zsh-syntax-highlighting`.
As you type commands, you will see a completion offered after the cursor in a muted gray color. This color can be changed by setting the `ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE` variable. See [configuration](#configuration).
If you press the <kbd>→</kbd> key (`forward-char` widget) or <kbd>End</kbd> (`end-of-line` widget) with the cursor at the end of the buffer, it will accept the suggestion, replacing the contents of the command line buffer with the suggestion.
## How to use
As you type commands, you will see a completion offered after the cursor, in a muted gray color (which can be changed, see [Configuration](#configuration)).
To accept the autosuggestion (replacing the command line contents), hit <kbd>End</kbd>, <kbd>Alt+F</kbd>, <kbd>Ctrl+F</kbd>, or any other key that moves the cursor to the right.
If the autosuggestion is not what you want, just ignore it: it won’t execute unless you accept it.
Any widget that moves the cursor to the right (forward-word, forward-char, end-of-line…) will accept parts of the suggested text.
For example, vi-mode users can do this:
```sh
# Accept suggestions without leaving insert mode
bindkey '^f' vi-forward-word
# or
bindkey '^f' vi-forward-blank-word
```
You can also use right arrow key to accept the suggested text as in Fish shell; see [Configuration](#configuration) section to enable it.
### Exposed widgets
This plugin defines some ZLE widgets (think about them as functions) which you can bind to some key using [bindkey](http://zshwiki.org/home/zle/bindkeys).
For example, to toggle autosuggestions using <kbd>Ctrl+T</kbd> add this to your .zshrc:
```sh
bindkey '^T' autosuggest-toggle
```
List of widgets:
- `autosuggest-toggle` – disable/enable autosuggestions.
- `autosuggest-execute-suggestion` – accept the suggestion and execute it.
If you invoke the `forward-word` widget, it will partially accept the suggestion up to the point that the cursor moves to.
## Configuration
You may override default global config variables after plugin load, i.e. put it to your .zshrc after the code that loads plugins.
- `AUTOSUGGESTION_HIGHLIGHT_COLOR` – suggestion highlight color, default is `'fg=8'`.
- `AUTOSUGGESTION_HIGHLIGHT_CURSOR` – highlight word after cursor, or not. Must be integer value `1` or `0`, default is `1`.
- `AUTOSUGGESTION_ACCEPT_RIGHT_ARROW` – complete entire suggestion with right arrow. Must be integer value `1` or `0`, default is `0` (right arrow completes one letter at a time).
You may want to override the default global config variables after sourcing the plugin. Default values of these variables can be found [here](/tarruda/zsh-autosuggestions/blob/master/src/config.zsh).
## Known Issues
### Suggestion Highlight Style
> When I hit <kbd>Tab</kbd> and autosuggestions is enabled, it deletes the previous line, and scrolls up the terminal.
Set `ZSH_AUTOSUGGEST_HIGHLIGHT_STYLE` to configure the style that the suggestion is shown with. The default is `fg=8`.
This usually happens when autosuggestions is used along with something like [“completion waiting dots.”](http://michael.thegrebs.com/2012/09/04/zsh-completion-waiting-dots/)
Check which widget is bind to the Tab key; run `bindkey "^I"`.
If it prints something other than `"^I" expand-or-complete`, then this may be the problem.
If you use [Oh My Zsh](https://github.com/robbyrussell/oh-my-zsh), then make sure that the variable `COMPLETION_WAITING_DOTS` is not set (it enables [this](https://github.com/robbyrussell/oh-my-zsh/blob/e55c715508a2f652fed741f2047c66dda2c6e5b0/lib/completion.zsh#L56-L64) problematic code).
### Widget Mapping
If you use module [editor](https://github.com/sorin-ionescu/prezto/tree/master/modules/editor) from [Prezto](https://github.com/sorin-ionescu/prezto), then you must comment out [these lines](https://github.com/sorin-ionescu/prezto/blob/a84ac5b0023d71c98bb28a68c550dc13f6c51945/modules/editor/init.zsh#L303-L304).
This plugin works by triggering custom behavior when certain [zle widgets](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Zle-Widgets) are invoked. You can add and remove widgets from these arrays to change the behavior of this plugin:
- `ZSH_AUTOSUGGEST_CLEAR_WIDGETS`: Widgets in this array will clear the suggestion when invoked.
- `ZSH_AUTOSUGGEST_MODIFY_WIDGETS`: Widgets in this array will modify the buffer and fetch a new suggestion when invoked.
- `ZSH_AUTOSUGGEST_ACCEPT_WIDGETS`: Widgets in this array will accept the suggestion when invoked.
- `ZSH_AUTOSUGGEST_PARTIAL_ACCEPT_WIDGETS`: Widgets in this array will partially accept the suggestion when invoked.
**Note:** These arrays must be set before calling `autosuggest_start`.
**Note:** A widget shouldn't belong to more than one of the above arrays.
### Key Bindings
This plugin provides two widgets that you can use with `bindkey`:
1. `autosuggest-accept`: Accepts the current suggestion.
2. `autosuggest-clear`: Clears the current suggestion.
For example, this would bind <kbd>ctrl</kbd> + <kbd>space</kbd> to accept the current suggestion.
```sh
bindkey '^ ' autosuggest-accept
```
## Compatibility With Other ZLE Plugins
### [`zsh-syntax-highlighting`](https://github.com/zsh-users/zsh-syntax-highlighting)
Source `zsh-autosuggestions.zsh` *before* `zsh-syntax-highlighting`.
Call `autosuggest_start` *after* sourcing `zsh-syntax-highlighting`.
For example:
```sh
source ~/.zsh/zsh-autosuggestions/dist/autosuggestions.zsh
source ~/.zsh/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
autosuggest_start
```
### [`zsh-history-substring-search`](https://github.com/zsh-users/zsh-history-substring-search)
When the buffer is empty and one of the `history-substring-search-up/down` widgets is invoked, it will call the `up/down-line-or-history` widget. If the `up/down-line-or-history` widgets are in `ZSH_AUTOSUGGEST_CLEAR_WIDGETS` (the list of widgets that clear the suggestion), this can create an infinite recursion, crashing the shell session.
For best results, you'll want to remove `up-line-or-history` and `down-line-or-history` from `ZSH_AUTOSUGGEST_CLEAR_WIDGETS`:
```
# Remove *-line-or-history widgets from list of widgets that clear the autosuggestion to avoid conflict with history-substring-search-* widgets
ZSH_AUTOSUGGEST_CLEAR_WIDGETS=("${(@)ZSH_AUTOSUGGEST_CLEAR_WIDGETS:#(up|down)-line-or-history}")
```
Additionally, the `history-substring-search-up` and `history-substring-search-down` widgets are not bound by default. You'll probably want to add them to `ZSH_AUTOSUGGEST_CLEAR_WIDGETS` so that the suggestion will be cleared when you start searching through history:
```sh
# Add history-substring-search-* widgets to list of widgets that clear the autosuggestion
ZSH_AUTOSUGGEST_CLEAR_WIDGETS+=(history-substring-search-up history-substring-search-down)
```
Make sure you add/remove these widgets *before* calling `autosuggest_start`.
For example:
```sh
source ~/.zsh/zsh-autosuggestions/dist/autosuggestions.zsh
source ~/Code/zsh-history-substring-search/zsh-history-substring-search.zsh
ZSH_AUTOSUGGEST_CLEAR_WIDGETS=("${(@)ZSH_AUTOSUGGEST_CLEAR_WIDGETS:#(up|down)-line-or-history}")
ZSH_AUTOSUGGEST_CLEAR_WIDGETS+=(history-substring-search-up history-substring-search-down)
autosuggest_start
```
## Uninstallation
1. Remove the code referencing this plugin from `~/.zshrc`.
2. Remove the git repository from your hard drive
```sh
rm -rf ~/.zsh/zsh-autosuggestions # Or wherever you installed
```

Changes in shUnit2 2.1.X
========================
Changes with 2.1.6
------------------
Removed all references to the DocBook documentation.
Simplified the 'src' structure.
Fixed error message in fail() that stated wrong number of required arguments.
Updated lib/versions.
Fixed bug in _shunit_mktempDir() where a failure occurred when the 'od' command was not present in /usr/bin.
Renamed shunit_tmpDir variable to SHUNIT_TMPDIR to closer match the standard
TMPDIR variable.
Added support for calling shunit2 as an executable, in addition to the existing
method of sourcing it in as a library. This allows users to keep tests working
despite the location of the shunit2 executable being different for each OS
distribution.
Issue #14: Improved handling of some strange chars (e.g. single and double
quotes) in messages.
Issue# 27: Fixed error message for assertSame().
Issue# 25: Added check and error message to user when phantom functions are
written to a partition mounted with noexec.
Issue# 11: Added support for defining functions like 'function someFunction()'.
Changes with 2.1.5
------------------
Issue# 1: Fixed bug pointed out by R Bernstein in the trap code where certain
types of exit conditions did not generate the ending report.
Issue# 2: Added assertNotEquals() assert.
Issue# 3: Moved check for unset variables out of shUnit2 into the unit tests.
Testing poorly written software blows up if this check is in, but it is only
interesting for shUnit2 itself. Added shunit_test_output.sh unit test for this.
Some shells still do not catch such errors properly (e.g. Bourne shell and BASH
2.x).
Added new custom assert in test_helpers to check for output to STDOUT, and none
to STDERR.
Replaced fatal message in the temp directory creation with a _shunit_fatal()
function call.
Fixed test_output unit test so it works now that the 'set -u' stuff was removed
for Issue# 3.
Flushed out the coding standards in the README.txt a bit more, and brought the
shunit2 code up to par with the documented standards.
Issue# 4: Completely changed the reporting output to be a closer match for
JUnit and PyUnit. As a result, tests are counted separately from assertions.
Provide public shunit_tmpDir variable that can be used by unit test scripts that
need automated and guaranteed cleanup.
Issue# 7: Fixed duplicated printing of messages passed to asserts.
Per code review, fixed wording of failSame() and failNotSame() messages.
Replaced version_info.sh with versions library and made appropriate changes in
other scripts to use it.
Added gen_test_results.sh to make releases easier.
Fixed bugs in shlib_relToAbsPath() in shlib.
Converted DocBook documentation to reStructuredText for easier maintenance. The
DocBook documentation is now considered obsolete, and will be removed in a
future release.
Issue# 5: Fixed the documentation around the usage of failures.
Issue# 9: Added unit tests and updated documentation to demonstrate the
requirement of quoting values twice when macros are used. This is due to how
shell parses arguments.
When an invalid number of arguments is passed to a function, the invalid number
is returned to the user so they are more aware of what the cause might be.
Changes with 2.1.4
------------------
Removed the _shunit_functionExists() function as it was dead code.
Fixed zsh version number check in version_info.
Fixed bug in last resort temporary directory creation.
Fixed off-by-one in exit value for scripts caught by the trap handler.
Added argument count error checking to all functions.
Added mkdir_test.sh example.
Moved src/test into src/shell to better match structure used with shFlags.
Fixed problem where null values were not handled properly under ksh.
Added support for outputting line numbers as part of assert messages.
Started documenting the coding standards, and changed some variable names as a
result.
Improved zsh version and option checks.
Renamed the __SHUNIT_VERSION variable to SHUNIT_VERSION.
Changes with 2.1.3
------------------
Added some explicit variable defaults, even though the variables are set, as
they sometimes behave strange when the script is canceled.
Additional workarounds for zsh compatibility.
shUnit2 now exits with a non-zero exit code if any of the tests failed. This was
done for automated testing frameworks. Tests that were skipped are not
considered failures, and do not affect the exit code.
Changed detection of STDERR output in unit tests.
Changes with 2.1.2
------------------
Unset additional variables that were missed.
Added checks and workarounds to improve zsh compatibility.
Added some argument count checks ``assertEquals()``, ``assertNull()``, and
``assertSame()``
Changes with 2.1.1
------------------
Fixed bug where ``fail()`` was not honoring skipping.
Fixed problem with ``docs-docbook-prep`` target that prevented it from working.
(Thanks to Bryan Larsen for pointing this out.)
Changed the test in ``assertFalse()`` so that any non-zero value registers as
false. (Credits to Bryan Larsen)
Major fiddling to bring more in line with `JUnit <http://junit.org/>`. Asserts
give better output when no message is given, and failures now just fail.
It was pointed out that the simple 'failed' message for a failed assert was not
only insufficient, it was nonstandard (when compared to JUnit) and didn't
provide the user with an expected vs actual result. The code was revised
somewhat to bring closer into alignment with JUnit (v4.3.1 specifically) so
that it feels more "normal". (Credits to Richard Jensen)
As part of the JUnit realignment, it was noticed that fail*() functions in
JUnit don't actually do any comparisons themselves. They only generate a
failure message. Updated the code to match.
Added self-testing unit tests. Kinda horkey, but they did find bugs during the
JUnit realignment.
Fixed the code for returning from asserts as the return was being called before
the unsetting of variables occurred. (Credits to Mathias Goldau)
The assert(True|False)() functions now accept an integer value for a
conditional test. A value of '0' is considered 'true', while any non-zero value
is considered 'false'.
All public functions now fill use default values to work properly with the '-x'
shell debugging flag.
Fixed the method of percent calculation for the report to get achieve better
accuracy.
Changes with 2.1.0 (since 2.0.1)
--------------------------------
This release is a branch of the 2.0.1 release.
Moving to `reStructured Text <http://docutils.sourceforge.net/rst.html>`_ for
the documentation.
Fixed problem with ``fail()``. The failure message was not properly printed.
Fixed the ``Makefile`` so that the DocBook XML and XSLT files would be
downloaded before parsing can continue.
Renamed the internal ``__SHUNIT_TRUE`` and ``__SHUNIT_FALSE`` variables to
``SHUNIT_TRUE`` and ``SHUNIT_FALSE`` so that unit tests can "use" them.
Added support for test "skipping". If skipping is turned on with the
``startSkip()`` function, ``assert`` and ``fail`` functions will return
immediately, and the skip will be recorded.
The report output format was changed to include the percentage for each test
result, rather than just those successful.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public
License along with this library; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.
<signature of Ty Coon>, 1 April 1990
Ty Coon, President of Vice
That's all there is to it!

DEPRECATED
This project is stored on SourceForge as http://sf.net/projects/shunit2. The
source code is stored in Subversion and can be accessed using the following
information.
Check out the code locally ::
$ svn co https://shunit2.svn.sourceforge.net/svnroot/shunit2/trunk/source/2.1 shunit2
Browse the code in a web browser:

- http://shunit2.svn.sourceforge.net/svnroot/shunit2/trunk/source/2.1/
Making a release
================
For these steps, it is assumed we are working with release 2.0.0.
Steps:
- write release notes
- update version
- finish changelog
- check all the code in
- tag the release
- export the release
- create tarball
- md5sum the tarball and sign with gpg
- update website
- post to SourceForge and Freshmeat
Write Release Notes
-------------------
This should be pretty self explanatory. Use one of the release notes from a
previous release as an example.
The versions of the various platforms and shells are included when the
master unit test script is run, or when ``bin/gen_test_results.sh`` is
used. To determine the versions of the installed shells by hand, use the
``lib/versions`` script.
Alternatively, do the following:
+-------+---------+-----------------------------------------------------------+
| Shell | OS | Notes |
+=======+=========+===========================================================+
| bash | | ``$ bash --version`` |
+-------+---------+-----------------------------------------------------------+
| dash | Linux | ``$ dpkg -l |grep dash`` |
+-------+---------+-----------------------------------------------------------+
| ksh | | ``$ ksh --version`` |
| | | -or- |
| | | ``$ echo 'echo $KSH_VERSION' |ksh`` |
| +---------+-----------------------------------------------------------+
| | Cygwin | see pdksh |
| +---------+-----------------------------------------------------------+
| | Solaris | ``$ strings /usr/bin/ksh |grep 'Version'`` |
+-------+---------+-----------------------------------------------------------+
| pdksh | | ``$ strings /bin/pdksh |grep 'PD KSH'`` |
| +---------+-----------------------------------------------------------+
| | Cygwin | look in the downloaded Cygwin directory |
+-------+---------+-----------------------------------------------------------+
| sh | Solaris | not possible |
+-------+---------+-----------------------------------------------------------+
| zsh | | ``$ zsh --version`` |
+-------+---------+-----------------------------------------------------------+
Update Version
--------------
Edit ``src/shell/shunit2`` and change the version number in the comment, as well
as in the ``SHUNIT_VERSION`` variable.
Finish Documentation
--------------------
Make sure that any remaining changes get put into the ``CHANGES-X.X.txt`` file.
Finish writing the ``RELEASE_NOTES-X.X.X.txt``. If necessary, run it
through the **fmt** command to make it pretty (hopefully it is already). ::
$ fmt -w 80 RELEASE_NOTES-2.0.0.txt >RELEASE_NOTES-2.0.0.txt.new
$ mv RELEASE_NOTES-2.0.0.txt.new RELEASE_NOTES-2.0.0.txt
We want to have an up-to-date version of the documentation in the release, so
we'd better build it. ::
$ pwd
.../shunit2/source/2.1
$ cd doc
$ RST2HTML_OPTS='--stylesheet-path=rst2html.css'
$ rst2html ${RST2HTML_OPTS} shunit2.txt >shunit2.html
$ rst2html ${RST2HTML_OPTS} README.txt >README.html
Check In All the Code
---------------------
This step is pretty self-explanatory ::

Tag the Release
---------------
::
$ pwd
.../shunit2/source
$ ls
2.0 2.1
$ svn cp -m "Release 2.0.0" 2.0 https://shunit2.googlecode.com/svn/tags/source/2.0.0
Export the Release
------------------
::
$ pwd
.../shunit2/builds
$ svn export https://shunit2.googlecode.com/svn/tags/source/2.0.0 shunit2-2.0.0
Create Tarball
--------------
::
$ tar cfz ../releases/shunit2-2.0.0.tgz shunit2-2.0.0
Sign the Tarball with gpg
-------------------------
::
$ cd ../releases
$ gpg --default-key kate.ward@forestent.com --detach-sign shunit2-2.0.0.tgz
Update Website
--------------
Again, pretty self-explanatory. Make sure to copy the GPG signature file. Once
that is done, make sure to tag the website so we can go back in time if needed.
::
$ pwd
.../shunit2
$ ls
source website
$ svn cp -m "Release 2.0.0" \
website https://shunit2.googlecode.com/svn/tags/website/20060916
Now, update the website. It too is held in Subversion, so **ssh** into the web
server and use ``svn up`` to grab the latest version.

Release Notes for shUnit2 2.1.0
===============================
This release was branched from shUnit2 2.0.1. It mostly adds new functionality,
but there are couple of bugs fixed from the previous release.
See the ``CHANGES-2.1.rst`` file for a full list of changes.
Tested Platforms
----------------
This list of platforms comes from the latest version of log4sh as shUnit2 is
used in the testing of log4sh on each of these platforms.
Cygwin
- bash 3.2.9(10)
- pdksh 5.2.14
Linux
- bash 3.1.17(1), 3.2.10(1)
- dash 0.5.3
- ksh 1993-12-28
- pdksh 5.2.14
- zsh 4.3.2 (does not work)
Mac OS X 10.4.8 (Darwin 8.8)
- bash 2.05b.0(1)
- ksh 1993-12-28
Solaris 8 U3 (x86)
- /bin/sh
- bash 2.03.0(1)
- ksh M-11/16/88i
Solaris 10 U2 (sparc)
- /bin/sh
- bash 3.00.16(1)
- ksh M-11/16/88i
Solaris 10 U2 (x86)
- /bin/sh
- bash 3.00.16(1)
- ksh M-11/16/88i
New Features
------------
Test skipping
Support added for test "skipping". A skip mode can be enabled so that
subsequent ``assert`` and ``fail`` functions that are called will be recorded
as "skipped" rather than as "passed" or "failed". This functionality can be
used such that when a set of tests makes sense on one platform but not on
another, they can be effectively disabled without altering the total number
of tests.
One example might be when something is supported under ``bash``, but not
under a standard Bourne shell.
New functions: ``startSkipping()``, ``endSkipping``, ``isSkipping``
Changes and Enhancements
------------------------
Moving to the use of `reStructured Text
<http://docutils.sourceforge.net/rst.html>`_ for documentation. It is easy to
read and edit in textual form, but converts nicely to HTML.
The report format has changed. Rather than including a simple "success"
percentage at the end, a percentage is given for each type of test.
Bug Fixes
---------
The ``fail()`` function did not output the optional failure message.
Fixed the ``Makefile`` so that the DocBook XML and XSLT files would be
downloaded before documentation parsing will continue.
Deprecated Features
-------------------
None.
Known Bugs and Issues
---------------------
None.

Release Notes for shUnit2 2.1.1
===============================
This is mainly a bug fix release, but it also incorporates a realignment with
the JUnit 4 code. Asserts now provide better failure messages, and the failure
functions no longer perform tests.
See the ``CHANGES-2.1.txt`` file for a full list of changes.

Changes and Enhancements
------------------------
The internal test in ``assertFalse()`` now accepts any non-zero value as false.
The ``assertTrue()`` and ``assertFalse()`` functions now accept an integer value
for a conditional test. A value of '0' is considered 'true', while any non-zero
value is considered 'false'.
Self-testing unit tests were added.
Bug Fixes
---------
The ``fail()`` assert now honors skipping.
The ``docs-docbook-prep`` target now works properly.
All asserts now properly unset their variables.
Deprecated Features
-------------------
None.
Known Bugs and Issues
---------------------

Release Notes for shUnit2 2.1.2
===============================
This release adds initial support for the zsh shell. Due to some differences
with this shell as compared with others, some special checks have been added,
and there are some extra requirements necessary when this shell is to be used.
To use zsh with shUnit2, the following two requirements must be met:
* The ``shwordsplit`` option must be set.
* The ``function_argzero`` option must be unset.

Release Notes for shUnit2 2.1.5
===============================
This release contains several bug fixes and changes. Additionally, it includes
a rewrite of the test output to better match JUnit and PyUnit.
This version also includes a slightly expanded set of coding standards by which
shUnit2 is coded. It should help anyone reading the code to better understand
it.

------------
Support added for output assert source line number as part of assert messages.
Issue #2: Added assertNotEquals() assert.
Provided a public ``shunit_tmpDir`` variable that can be used by unit test
scripts that need automated and guaranteed cleanup.
Changes and Enhancements
------------------------
Issue #3: Removed the check for unset variables as shUnit2 should not expect
scripts being tested to be clean.
Issue #4: Rewrote the test summary. It is now greatly simplified and much more
script friendly.
Issue #5: Fixed the documentation around the usage of failures.
Issue #9: Added unit tests and improved documentation around the use of macros.
Code updated to meet documented coding standards.
Improved code reuse of ``_shunit_exit()`` and ``_shunit_fatal()`` functions.
All output except shUnit2 error messages now goes to STDOUT.
Converted DocBook documentation to reStructuredText for easier maintenance.
Bug Fixes
---------
Issue #1: Fixed bug in rap code where certain types of exit conditions did not
generate the ending report.
Issue #7: Fixed duplicated printing of messages passed to asserts.
Fixed bugs in ``shlib_relToAbsPath()`` in ``shlib``.
Deprecated Features
-------------------
None.
Known Bugs and Issues
---------------------
Zsh requires the ``shwordsplit`` option to be set. See the documentation for
examples of how to do this.
Line numbers in assert messages do not work properly with BASH 2.x.
The Bourne shell of Solaris, BASH 2.x, and Zsh 3.0.x do not properly catch the
SIGTERM signal. As such, shell interpreter failures due to such things as
unbound variables cannot be caught. (See ``shunit_test_misc.sh``)

Release Notes for shUnit2 2.1.6
===============================
This release contains bug fixes and changes. It is also the first release to
support running shunit2 as a standalone program.
Please read the Shell Errata section of the documentation for guidance on how

See the ``CHANGES-2.1.txt`` file for a full list of changes.
New Features
------------
Support for running shUnit2 as a standalone program. This makes it possible for
users to execute their unit tests in a manner that is not dependent on the
location an OS distribution maintainer chose to place shUnit2 in the file
system.
Added support for functions defined like 'function someFunction()'.
Changes and Enhancements
------------------------
Renamed the public ``shunit_tmpDir`` variable to ``SHUNIT_TMPDIR`` to be more
consistent with the ``TMPDIR`` variable.
Bug Fixes
---------
Fixed issue where shunit2 would fail on some distributions when creating a
temporary directory because the **od** command was not present.
Deprecated Features
-------------------
None.
Known Bugs and Issues

Coding Standards
================
Variable and Function Names
---------------------------
All shUnit2 specific constants, variables, and functions will be prefixed
appropriately with 'shunit'. This is to distinguish usage in the shUnit2 code
from users own scripts so that the shell name space remains predictable to
users. The exceptions here are the standard ``assertEquals``, etc. functions.
All non-builtin constants and variables will be surrouned with squiggle
brackets, e.g. '${shunit_someVariable}' to improve code readability.
Due to some shells not supporting local variables in functions, care in the
naming and use of variables, both public and private, is very important.
Accidental overriding of the variables can occur easily if care is not taken as
all variables are technically global variables in some shells.
+----------------------------------+---------------------------+
| *type* | *sample* |
+==================================+===========================+
| global public constant | ``SHUNIT_TRUE`` |
+----------------------------------+---------------------------+
| global private constant | ``__SHUNIT_SHELL_FLAGS`` |
+----------------------------------+---------------------------+
| global public variable | not used |
+----------------------------------+---------------------------+
| global private variable | ``__shunit_someVariable`` |
+----------------------------------+---------------------------+
| global macro | ``_SHUNIT_SOME_MACRO_`` |
+----------------------------------+---------------------------+
| public function | ``assertEquals`` |
+----------------------------------+---------------------------+
| public function, local variable | ``shunit_someVariable_`` |
+----------------------------------+---------------------------+
| private function | ``_shunit_someFunction`` |
+----------------------------------+---------------------------+
| private function, local variable | ``_shunit_someVariable_`` |
+----------------------------------+---------------------------+
Where it makes sense, variables can have the first letter of the second and
later words capitalized. For example, the local variable name for the total
number of test cases seen might be ``shunit_totalTestsSeen_``.
Local Variable Cleanup
----------------------
As many shells do not support local variables, no support for cleanup of
variables is present either. As such, all variables local to a function must be
cleared up with the ``unset`` command at the end of each function.
Indentation
-----------
Code block indentation is two (2) spaces, and tabs may not be used. ::
if [ -z 'some string' ]; then
someFunction
fi
Lines of code should be no longer than 80 characters unless absolutely
necessary. When lines are wrapped using the backslash character '\', subsequent
lines should be indented with four (4) spaces so as to differentiate from the
standard spacing of two characters. Tabs may *not* be used. ::
for x in some set of very long set of arguments that make for a very long \
that extends much too long for one line
do
echo ${x}
done

Design Doc for shUnit
shUnit is based upon JUnit. The initial ideas for the script came from the book
"Pragmatic Unit Testing - In Java with JUnit" by Andrew Hunt and David Thomas.
The script was written to perform unit testing for log4sh. log4sh had grown
enough that it was becoming difficult to easily test and and verify that the
tests passed for the many different operating systems on which it was being
used.
The functions in shUnit are meant to match those in JUnit as much as possible
where shell allows. In the initial version, there will be no concept of
exceptions (as normal POSIX shell has no concept of them) but attempts to trap
problems will be done.
Programatic Standards:
* SHUNIT_TRUE - public global constant
* __SHUNIT_SHELL_FLAGS - private global constant
* __shunit_oldShellFlags - private global variable
* assertEquals - public unit test function
* shunit_publicFunc - public shUnit function; can be called from parent unit
test script
* _shunit_privateFunc - private shUnit function; should not be called from
parent script. meant for internal use by shUnit
* _su_myVar - variable inside a public function. prefixing with '_su_' to
reduce the chances that a variable outside of shUnit will be overridden.
* _su__myVar - variable inside a private function. prefixing with '_su__' to
reduce the chances that a variable in a shUnit public function, or a variable
outside of shUnit will be overridden.

<h1><a class="toc-backref" href="#id2">Introduction</a></h1>
<p>shUnit2 was originally developed to provide a consistent testing solution for
<a class="reference external" href="http://log4sh.sourceforge.net/">log4sh</a>, a shell based logging framework similar to <a class="reference external" href="http://logging.apache.org/">log4j</a>. During the
development of that product, a repeated problem of having things work just fine
under one shell (<tt class="docutils literal">/bin/bash</tt> on Linux to be specific), and then not working
under another shell (<tt class="docutils literal">/bin/sh</tt> on Solaris) kept coming up. Although several
simple tests were run, they were not adequate and did not catch some corner
cases. The decision was finally made to write a proper unit test framework after
multiple brown-bag releases were made. <em>Research was done to look for an
existing product that met the testing requirements, but no adequate product was
found.</em></p>
<p>Tested Operating Systems (varies over time)</p>
<ul class="simple">
<li>Cygwin</li>
<li>FreeBSD (user supported)</li>
<li>Linux (Gentoo, Ubuntu)</li>
<li>Mac OS X</li>
<li>Solaris 8, 9, 10 (inc. OpenSolaris)</li>
</ul>
<p>Tested Shells</p>
<ul class="simple">
<li>Bourne Shell (<strong>sh</strong>)</li>
<li>BASH - GNU Bourne Again SHell (<strong>bash</strong>)</li>
<li>DASH (<strong>dash</strong>)</li>
<li>Korn Shell (<strong>ksh</strong>)</li>
<li>pdksh - Public Domain Korn Shell (<strong>pdksh</strong>)</li>
<li>zsh - Zsh (<strong>zsh</strong>) (since 2.1.2) <em>please see the Zsh shell errata for more
information</em></li>
</ul>

<h1><a class="toc-backref" href="#id5">Quickstart</a></h1>
<p>This section will give a very quick start to running unit tests with shUnit2.
More information is located in later sections.</p>
<p>Here is a quick sample script to show how easy it is to write a unit test in
shell. <em>Note: the script as it stands expects that you are running it from the
``examples`` directory.</em></p>
<pre class="literal-block">
#! /bin/sh
# file: examples/equality_test.sh
testEquality()
{
assertEquals 1 1
}
# load shunit2
. ../src/shell/shunit2
</pre>
<p>Running the unit test should give results similar to the following.</p>
<pre class="literal-block">
testEquality
Ran 1 test.
OK
</pre>
<p>W00t! You've just run your first successful unit test. So, what just happened?
Quite a bit really, and it all happened simply by sourcing the <tt class="docutils literal">shunit2</tt>
library. The basic functionality for the script above goes like this:</p>
<ul class="simple">
<li>When shUnit2 is sourced, it will walk through any functions defined whose
namestart with the string <tt class="docutils literal">test</tt> and add those to an internal list of tests
to execute. Once a list of test functions to be run has been determined,
shunit2 will go to work.</li>
<li>Before any tests are executed, shUnit2 again looks for a function, this time
one named <tt class="docutils literal">oneTimeSetUp()</tt>. If it exists, it will be run. This function is
normally used to setup the environment for all tests to be run. Things like
creating directories for output or setting environment variables are good to
place here. Just so you know, you can also declare a corresponding function
named <tt class="docutils literal">oneTimeTearDown()</tt> function that does the same thing, but once all
the tests have been completed. It is good for removing temporary directories,
etc.</li>
<li>shUnit2 is now ready to run tests. Before doing so though, it again looks for
another function that might be declared, one named <tt class="docutils literal">setUp()</tt>. If the
function exists, it will be run before each test. It is good for resetting the
environment so that each test starts with a clean slate. At this stage, the
first test is finally run. The success of the test is recorded for a report
that will be generated later. After the test is run, shUnit2 looks for a final
function that might be declared, one named <tt class="docutils literal">tearDown()</tt>. If it exists, it
will be run after each test. It is a good place for cleaning up after each
test, maybe doing things like removing files that were created, or removing
directories. This set of steps, <tt class="docutils literal">setUp()</tt> &gt; <tt class="docutils literal">test()</tt> &gt; <tt class="docutils literal">tearDown()</tt>, is
repeated for all of the available tests.</li>
<li>Once all the work is done, shUnit2 will generate the nice report you saw
above. A summary of all the successes and failures will be given so that you
know how well your code is doing.</li>
</ul>
<p>We should now try adding a test that fails. Change your unit test to look like
this.</p>
<pre class="literal-block">
#! /bin/sh
# file: examples/party_test.sh
testEquality()
{
assertEquals 1 1
}
testPartyLikeItIs1999()
{
year=`date '+%Y'`
assertEquals &quot;It's not 1999 :-(&quot; \
'1999' &quot;${year}&quot;
}
# load shunit2
. ../src/shell/shunit2
</pre>
<p>So, what did you get? I guess it told you that this isn't 1999. Bummer, eh?
Hopefully, you noticed a couple of things that were different about the second
test. First, we added an optional message that the user will see if the assert
fails. Second, we did comparisons of strings instead of integers as in the first
test. It doesn't matter whether you are testing for equality of strings or
integers. Both work equally well with shUnit2.</p>
<p>Hopefully, this is enough to get you started with unit testing. If you want a
ton more examples, take a look at the tests provided with <a class="reference external" href="http://log4sh.sourceforge.net/">log4sh</a> or <a class="reference external" href="http://shflags.googlecode.com/">shFlags</a>.
Both provide excellent examples of more advanced usage. shUnit2 was after all
written to help with the unit testing problems that <a class="reference external" href="http://log4sh.sourceforge.net/">log4sh</a> had.</p>

<h2><a class="toc-backref" href="#id16">Including Line Numbers in Asserts (Macros)</a></h2>
<p>If you include lots of assert statements in an individual test function, it can
become difficult to determine exactly which assert was thrown unless your
messages are unique. To help somewhat, line numbers can be included in the
assert messages. To enable this, a special shell &quot;macro&quot; must be used rather
than the standard assert calls. <em>Shell doesn't actually have macros; the name is
used here as the operation is similar to a standard macro.</em></p>
<p>For example, to include line numbers for a <tt class="docutils literal">assertEquals()</tt> function call,
replace the <tt class="docutils literal">assertEquals()</tt> with <tt class="docutils literal">${_ASSERT_EQUALS_}</tt>.</p>
<p>Example&nbsp;--&nbsp;Asserts with and without line numbers</p>
<pre class="literal-block">
#! /bin/sh
# file: examples/lineno_test.sh
testLineNo()
{
# this assert will have line numbers included (e.g. &quot;ASSERT:[123] ...&quot;)
echo &quot;ae: ${_ASSERT_EQUALS_}&quot;
${_ASSERT_EQUALS_} 'not equal' 1 2
# this assert will not have line numbers included (e.g. &quot;ASSERT: ...&quot;)
assertEquals 'not equal' 1 2
}
# load shunit2
. ../src/shell/shunit2
</pre>
<p>Notes:</p>
<ol class="arabic">
<li><p class="first">Due to how shell parses command-line arguments, all strings used with macros
should be quoted twice. Namely, single-quotes must be converted to
single-double-quotes, and vice-versa. If the string being passed is
absolutely for sure not empty, the extra quoting is not necessary.</p>

<div class="section" id="test-skipping">
<h2><a class="toc-backref" href="#id17">Test Skipping</a></h2>
<p>There are times where the test code you have written is just not applicable to
the system you are running on. This section describes how to skip these tests
but maintain the total test count.</p>
<p>Probably the easiest example would be shell code that is meant to run under the
<strong>bash</strong> shell, but the unit test is running under the Bourne shell. There are
things that just won't work. The following test code demonstrates two sample
functions, one that will be run under any shell, and the another that will run
only under the <strong>bash</strong> shell.</p>
<p>Example&nbsp;-- math include</p>
<pre class="literal-block">
# available as examples/math.inc
add_generic()
{
num_a=$1
num_b=$2
expr $1 + $2
}
add_bash()
{
num_a=$1
num_b=$2
echo $(($1 + $2))
}
</pre>
<p>And here is a corresponding unit test that correctly skips the <tt class="docutils literal">add_bash()</tt>
function when the unit test is not running under the <strong>bash</strong> shell.</p>
<p>Example&nbsp;-- math unit test</p>
<pre class="literal-block">
#! /bin/sh
# available as examples/math_test.sh
testAdding()
{
result=`add_generic 1 2`
assertEquals \
&quot;the result of '${result}' was wrong&quot; \
3 &quot;${result}&quot;
# disable non-generic tests
[ -z &quot;${BASH_VERSION:-}&quot; ] &amp;&amp; startSkipping
result=`add_bash 1 2`
assertEquals \
&quot;the result of '${result}' was wrong&quot; \
3 &quot;${result}&quot;
}
oneTimeSetUp()
{
# load include to test
. ./math.inc
}
# load and run shUnit2
. ../src/shell/shunit2
</pre>
<p>Running the above test under the <strong>bash</strong> shell will result in the following
output.</p>
<pre class="literal-block">
$ /bin/bash math_test.sh
testAdding
Ran 1 test.
OK
</pre>
<p>But, running the test under any other Unix shell will result in the following
output.</p>
<pre class="literal-block">
$ /bin/ksh math_test.sh
testAdding
Ran 1 test.
OK (skipped=1)
</pre>
<p>As you can see, the total number of tests has not changed, but the report
indicates that some tests were skipped.</p>
<p>Skipping can be controlled with the following functions: <tt class="docutils literal">startSkipping()</tt>,
<tt class="docutils literal">stopSkipping()</tt>, and <tt class="docutils literal">isSkipping()</tt>. Once skipping is enabled, it will
remain enabled until the end of the current test function call, after which
skipping is disabled.</p>

shUnit2 2.1.x Documentation
===========================
Abstract
========
shUnit2_ is a xUnit_ unit test framework for Bourne based shell scripts, and it
is designed to work in a similar manner to JUnit_, PyUnit_, etc.. If you have
ever had the desire to write a unit test for a shell script, shUnit2 can do the
job.
.. contents:: Table of Contents
:depth: 2
Introduction
============
shUnit2 was originally developed to provide a consistent testing solution for
log4sh_, a shell based logging framework similar to log4j_. During the
development of that product, a repeated problem of having things work just fine
under one shell (``/bin/bash`` on Linux to be specific), and then not working
under another shell (``/bin/sh`` on Solaris) kept coming up. Although several
simple tests were run, they were not adequate and did not catch some corner
cases. The decision was finally made to write a proper unit test framework after
multiple brown-bag releases were made. *Research was done to look for an
existing product that met the testing requirements, but no adequate product was
found.*
Tested Operating Systems (varies over time)
- Cygwin
- FreeBSD (user supported)
- Linux (Gentoo, Ubuntu)
- Mac OS X
- Solaris 8, 9, 10 (inc. OpenSolaris)
Tested Shells
- Bourne Shell (**sh**)
- BASH - GNU Bourne Again SHell (**bash**)
- DASH (**dash**)
- Korn Shell (**ksh**)
- pdksh - Public Domain Korn Shell (**pdksh**)
- zsh - Zsh (**zsh**) (since 2.1.2) *please see the Zsh shell errata for more
information*
See the appropriate Release Notes for this release
(``doc/RELEASE_NOTES-X.X.X.txt``) for the list of actual versions tested.
Credits / Contributors
----------------------
A list of contributors to shUnit2 can be found in the source archive in
``doc/contributors.txt``. Many thanks go out to all those who have contributed
to make this a better tool.
shUnit2 is the original product of many hours of work by Kate Ward, the primary
author of the code. For other products by her, look up log4sh_ or shFlags_, or

Feedback is most certainly welcome for this document. Send your additions,
comments and criticisms to the shunit2-users@google.com mailing list.
Quickstart
==========
This section will give a very quick start to running unit tests with shUnit2.
More information is located in later sections.
Here is a quick sample script to show how easy it is to write a unit test in
shell. *Note: the script as it stands expects that you are running it from the
``examples`` directory.* ::
#! /bin/sh
# file: examples/equality_test.sh
testEquality()
{
assertEquals 1 1
}
# load shunit2
. ../src/shell/shunit2
Running the unit test should give results similar to the following. ::
testEquality
Ran 1 test.
OK
W00t! You've just run your first successful unit test. So, what just happened?
Quite a bit really, and it all happened simply by sourcing the ``shunit2``
library. The basic functionality for the script above goes like this:
- When shUnit2 is sourced, it will walk through any functions defined whose
namestart with the string ``test`` and add those to an internal list of tests
to execute. Once a list of test functions to be run has been determined,
shunit2 will go to work.
- Before any tests are executed, shUnit2 again looks for a function, this time
one named ``oneTimeSetUp()``. If it exists, it will be run. This function is
normally used to setup the environment for all tests to be run. Things like
creating directories for output or setting environment variables are good to
place here. Just so you know, you can also declare a corresponding function
named ``oneTimeTearDown()`` function that does the same thing, but once all
the tests have been completed. It is good for removing temporary directories,
etc.
- shUnit2 is now ready to run tests. Before doing so though, it again looks for
another function that might be declared, one named ``setUp()``. If the
function exists, it will be run before each test. It is good for resetting the
environment so that each test starts with a clean slate. At this stage, the
first test is finally run. The success of the test is recorded for a report
that will be generated later. After the test is run, shUnit2 looks for a final
function that might be declared, one named ``tearDown()``. If it exists, it
will be run after each test. It is a good place for cleaning up after each
test, maybe doing things like removing files that were created, or removing
directories. This set of steps, ``setUp()`` > ``test()`` > ``tearDown()``, is
repeated for all of the available tests.
- Once all the work is done, shUnit2 will generate the nice report you saw
above. A summary of all the successes and failures will be given so that you
know how well your code is doing.
We should now try adding a test that fails. Change your unit test to look like
this. ::
#! /bin/sh
# file: examples/party_test.sh
testEquality()
{
assertEquals 1 1
}
testPartyLikeItIs1999()
{
year=`date '+%Y'`
assertEquals "It's not 1999 :-(" \
'1999' "${year}"
}
# load shunit2
. ../src/shell/shunit2
So, what did you get? I guess it told you that this isn't 1999. Bummer, eh?
Hopefully, you noticed a couple of things that were different about the second
test. First, we added an optional message that the user will see if the assert
fails. Second, we did comparisons of strings instead of integers as in the first
test. It doesn't matter whether you are testing for equality of strings or
integers. Both work equally well with shUnit2.
Hopefully, this is enough to get you started with unit testing. If you want a
ton more examples, take a look at the tests provided with log4sh_ or shFlags_.
Both provide excellent examples of more advanced usage. shUnit2 was after all
written to help with the unit testing problems that log4sh_ had.
Function Reference
==================
General Info
------------
Any string values passed should be properly quoted -- they should must be
surrounded by single-quote (') or double-quote (") characters -- so that the
shell will properly parse them.
Asserts
-------
``assertEquals [message] expected actual``
Asserts that *expected* and *actual* are equal to one another. The *expected*
and *actual* values can be either strings or integer values as both will be
treated as strings. The *message* is optional, and must be quoted.
``assertNotEquals [message] expected actual``
Asserts that *unexpected* and *actual* are not equal to one another. The
*unexpected* and *actual* values can be either strings or integer values as
both will be treaded as strings. The *message* is optional, and must be
quoted.
``assertSame [message] expected actual``
This function is functionally equivalent to ``assertEquals``.
``assertNotSame [message] unexpected actual``
This function is functionally equivalent to ``assertNotEquals``.
``assertNull [message] value``
Asserts that *value* is *null*, or in shell terms, a zero-length string. The
*value* must be a string as an integer value does not translate into a
zero-length string. The *message* is optional, and must be quoted.
``assertNotNull [message] value``
Asserts that *value* is *not null*, or in shell terms, a non-empty string. The
*value* may be a string or an integer as the later will be parsed as a
non-empty string value. The *message* is optional, and must be quoted.
``assertTrue [message] condition``
Asserts that a given shell test *condition* is *true*. The condition can be as
simple as a shell *true* value (the value ``0`` -- equivalent to
``${SHUNIT_TRUE}``), or a more sophisticated shell conditional expression. The
*message* is optional, and must be quoted.
A sophisticated shell conditional expression is equivalent to what the **if**
or **while** shell built-ins would use (more specifically, what the **test**
command would use). Testing for example whether some value is greater than
another value can be done this way. ::
assertTrue "[ 34 -gt 23 ]"
Testing for the ability to read a file can also be done. This particular test
will fail. ::
assertTrue 'test failed' "[ -r /some/non-existant/file' ]"
As the expressions are standard shell **test** expressions, it is possible to
string multiple expressions together with ``-a`` and ``-o`` in the standard
fashion. This test will succeed as the entire expression evaluates to *true*.
::
assertTrue 'test failed' '[ 1 -eq 1 -a 2 -eq 2 ]'
*One word of warning: be very careful with your quoting as shell is not the
most forgiving of bad quoting, and things will fail in strange ways.*
``assertFalse [message] condition``
Asserts that a given shell test *condition* is *false*. The condition can be
as simple as a shell *false* value (the value ``1`` -- equivalent to
``${SHUNIT_FALSE}``), or a more sophisticated shell conditional expression.
The *message* is optional, and must be quoted.
*For examples of more sophisticated expressions, see ``assertTrue``.*
Failures
--------
Just to clarify, failures **do not** test the various arguments against one
another. Failures simply fail, optionally with a message, and that is all they
do. If you need to test arguments against one another, use asserts.
If all failures do is fail, why might one use them? There are times when you may
have some very complicated logic that you need to test, and the simple asserts
provided are simply not adequate. You can do your own validation of the code,
use an ``assertTrue ${SHUNIT_TRUE}`` if your own tests succeeded, and use a
failure to record a failure.
``fail [message]``
Fails the test immediately. The *message* is optional, and must be quoted.
``failNotEquals [message] unexpected actual``
Fails the test immediately, reporting that the *unexpected* and *actual*
values are not equal to one another. The *message* is optional, and must be
quoted.
*Note: no actual comparison of unexpected and actual is done.*
``failSame [message] expected actual``
Fails the test immediately, reporting that the *expected* and *actual* values
are the same. The *message* is optional, and must be quoted.
*Note: no actual comparison of expected and actual is done.*
``failNotSame [message] expected actual``
Fails the test immediately, reporting that the *expected* and *actual* values
are not the same. The *message* is optional, and must be quoted.
*Note: no actual comparison of expected and actual is done.*
Setup/Teardown
--------------
``oneTimeSetUp``
This function can be be optionally overridden by the user in their test suite.
If this function exists, it will be called once before any tests are run. It
is useful to prepare a common environment for all tests.
``oneTimeTearDown``
This function can be be optionally overridden by the user in their test suite.
If this function exists, it will be called once after all tests are completed.
It is useful to clean up the environment after all tests.
``setUp``
This function can be be optionally overridden by the user in their test suite.
If this function exists, it will be called before each test is run. It is
useful to reset the environment before each test.
``tearDown``
This function can be be optionally overridden by the user in their test suite.
If this function exists, it will be called after each test completes. It is
useful to clean up the environment after each test.
Skipping
--------
``startSkipping``
This function forces the remaining *assert* and *fail* functions to be
"skipped", i.e. they will have no effect. Each function skipped will be
recorded so that the total of asserts and fails will not be altered.
``endSkipping``
This function returns calls to the *assert* and *fail* functions to their
default behavior, i.e. they will be called.
``isSkipping``
This function returns the current state of skipping. It can be compared
against ``${SHUNIT_TRUE}`` or ``${SHUNIT_FALSE}`` if desired.
Suites
------
The default behavior of shUnit2 is that all tests will be found dynamically. If
you have a specific set of tests you want to run, or you don't want to use the
standard naming scheme of prefixing your tests with ``test``, these functions
are for you. Most users will never use them though.
``suite``
This function can be optionally overridden by the user in their test suite.
If this function exists, it will be called when ``shunit2`` is sourced. If it
does not exist, shUnit2 will search the parent script for all functions
beginning with the word ``test``, and they will be added dynamically to the
test suite.
``suite_addTest name``
This function adds a function named *name* to the list of tests scheduled for
execution as part of this test suite. This function should only be called from
within the ``suite()`` function.
Advanced Usage
==============
This section covers several advanced usage topics.
Some constants you can use
--------------------------
There are several constants provided by shUnit2 as variables that might be of
use to you.
Predefined
================== ===========================================================
``SHUNIT_VERSION`` The version of shUnit2 you are running.
``SHUNIT_TRUE`` Standard shell *true* value (the integer value 0).
``SHUNIT_FALSE`` Standard shell *false* value (the integer value 1).
``SHUNIT_ERROR`` The integer value 2.
``SHUNIT_TMPDIR`` Path to temporary directory that will be automatically
cleaned up upon exit of shUnit2.
================== ===========================================================
User defined
================== ===========================================================
``SHUNIT_PARENT`` The filename of the shell script containing the tests. This
is needed specifically for Zsh support.
================== ===========================================================
Error handling
--------------
The constants values ``SHUNIT_TRUE``, ``SHUNIT_FALSE``, and ``SHUNIT_ERROR`` are
returned from nearly every function to indicate the success or failure of the
function. Additionally the variable ``flags_error`` is filled with a detailed
error message if any function returns with a ``SHUNIT_ERROR`` value.
Including Line Numbers in Asserts (Macros)
------------------------------------------
If you include lots of assert statements in an individual test function, it can
become difficult to determine exactly which assert was thrown unless your
messages are unique. To help somewhat, line numbers can be included in the
assert messages. To enable this, a special shell "macro" must be used rather
than the standard assert calls. *Shell doesn't actually have macros; the name is
used here as the operation is similar to a standard macro.*
For example, to include line numbers for a ``assertEquals()`` function call,
replace the ``assertEquals()`` with ``${_ASSERT_EQUALS_}``.
Example -- Asserts with and without line numbers ::
#! /bin/sh
# file: examples/lineno_test.sh
testLineNo()
{
# this assert will have line numbers included (e.g. "ASSERT:[123] ...")
echo "ae: ${_ASSERT_EQUALS_}"
${_ASSERT_EQUALS_} 'not equal' 1 2
# this assert will not have line numbers included (e.g. "ASSERT: ...")
assertEquals 'not equal' 1 2
}
# load shunit2
. ../src/shell/shunit2
Notes:
#. Due to how shell parses command-line arguments, all strings used with macros
should be quoted twice. Namely, single-quotes must be converted to
single-double-quotes, and vice-versa. If the string being passed is
absolutely for sure not empty, the extra quoting is not necessary.
Normal ``assertEquals`` call. ::
assertEquals 'some message' 'x' ''
Macro ``_ASSERT_EQUALS_`` call. Note the extra quoting around the *message*
and the *null* value. ::
_ASSERT_EQUALS_ '"some message"' 'x' '""'
#. Line numbers are not supported in all shells. If a shell does not support
them, no errors will be thrown. Supported shells include: **bash** (>=3.0),
**ksh**, **pdksh**, and **zsh**.
Test Skipping
-------------
There are times where the test code you have written is just not applicable to
the system you are running on. This section describes how to skip these tests
but maintain the total test count.
Probably the easiest example would be shell code that is meant to run under the
**bash** shell, but the unit test is running under the Bourne shell. There are
things that just won't work. The following test code demonstrates two sample
functions, one that will be run under any shell, and the another that will run
only under the **bash** shell.
Example -- math include ::
# available as examples/math.inc
add_generic()
{
num_a=$1
num_b=$2
expr $1 + $2
}
add_bash()
{
num_a=$1
num_b=$2
echo $(($1 + $2))
}
And here is a corresponding unit test that correctly skips the ``add_bash()``
function when the unit test is not running under the **bash** shell.
Example -- math unit test ::
#! /bin/sh
# available as examples/math_test.sh
testAdding()
{
result=`add_generic 1 2`
assertEquals \
"the result of '${result}' was wrong" \
3 "${result}"
# disable non-generic tests
[ -z "${BASH_VERSION:-}" ] && startSkipping
result=`add_bash 1 2`
assertEquals \
"the result of '${result}' was wrong" \
3 "${result}"
}
oneTimeSetUp()
{
# load include to test
. ./math.inc
}
# load and run shUnit2
. ../src/shell/shunit2
Running the above test under the **bash** shell will result in the following
output. ::
$ /bin/bash math_test.sh
testAdding
Ran 1 test.
OK
But, running the test under any other Unix shell will result in the following
output. ::
$ /bin/ksh math_test.sh
testAdding
Ran 1 test.
OK (skipped=1)
As you can see, the total number of tests has not changed, but the report
indicates that some tests were skipped.
Skipping can be controlled with the following functions: ``startSkipping()``,
``stopSkipping()``, and ``isSkipping()``. Once skipping is enabled, it will
remain enabled until the end of the current test function call, after which
skipping is disabled.

Getting help
------------
For help, please send requests to either the shunit2-users@googlegroups.com
mailing list (archives available on the web at
http://groups.google.com/group/shunit2-users) or directly to
Kate Ward <kate dot ward at forestent dot com>.
Zsh
---
For compatibility with Zsh, there is one requirement that must be met -- the
``shwordsplit`` option must be set. There are three ways to accomplish this.
#. In the unit-test script, add the following shell code snippet before sourcing
the ``shunit2`` library. ::
setopt shwordsplit
#. When invoking **zsh** from either the command-line or as a script with
``#!``, add the ``-y`` parameter. ::
#! /bin/zsh -y
#. When invoking **zsh** from the command-line, add ``-o shwordsplit --`` as
parameters before the script name. ::
$ zsh -o shwordsplit -- some_script
