# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at kate.ward@forestent.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
## Attribution

# shUnit2
shUnit2 is a [xUnit](http://en.wikipedia.org/wiki/XUnit) unit test framework for Bourne based shell scripts, and it is designed to work in a similar manner to [JUnit](http://www.junit.org), [PyUnit](http://pyunit.sourceforge.net), etc.. If you have ever had the desire to write a unit test for a shell script, shUnit2 can do the job.

## <a name="introduction"></a> Introduction
shUnit2 was originally developed to provide a consistent testing solution for [log4sh][log4sh], a shell based logging framework similar to [log4j](http://logging.apache.org). 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.

## <a name="quickstart"></a> 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._
```sh
#! /bin/sh
# file: examples/equality_test.sh
testEquality() {
assertEquals 1 1
}
# Load shUnit2.
. ./shunit2
```
Running the unit test should give results similar to the following.
```console
$ cd examples
$ ./equality_test.sh
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 name starts 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.
```sh
#! /bin/sh
# file: examples/party_test.sh
testEquality() {
assertEquals 1 1
}
testPartyLikeItIs1999() {
year=`date '+%Y'`
assertEquals "It's not 1999 :-(" '1999' "${year}"
}
# Load shUnit2.
. ./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][log4sh] or [shFlags][shflags]. Both provide excellent examples of more advanced usage. shUnit2 was after all written to meet the unit testing need that [log4sh][log4sh] had.

## <a name="function-reference"></a> Function Reference
### <a name="general-info"></a> 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.
### <a name="asserts"></a> 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] unexpected 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`._
### <a name="failures"></a> 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._
### <a name="setup-teardown"></a> 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.
### <a name="skipping"></a> 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.
### <a name="suites"></a> 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.
---
## <a name="advanced-usage"></a> Advanced Usage
### <a name="some-constants-you-can-use"></a> Some constants you can use
There are several constants provided by shUnit2 as variables that might be of use to you.
*Predefined*
| Constant | Value |
| --------------- | ----- |
| 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. |
| SHUNIT\_VERSION | The version of shUnit2 you are running. |
*User defined*
| Constant | Value |
| ----------------- | ----- |
| SHUNIT\_CMD\_EXPR | Override which `expr` command is used. By default `expr` is used, except on BSD systems where `gexpr` is used. |
| SHUNIT\_COLOR | Enable colorized output. Options are 'auto', 'always', or 'never', with 'auto' being the default. |
| SHUNIT\_PARENT | The filename of the shell script containing the tests. This is needed specifically for Zsh support. |
| SHUNIT\_TEST\_PREFIX | Define this variable to add a prefix in front of each test name that is output in the test report. |
### <a name="error-handling"></a> 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.
### <a name="including-line-numbers-in-asserts-macros"></a> 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_
```sh
#! /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.
. ./shunit2
```
Notes:
1. 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.<br/><br/>Normal `assertEquals` call.<br/>`assertEquals 'some message' 'x' ''`<br/><br/>Macro `_ASSERT_EQUALS_` call. Note the extra quoting around the _message_ and the _null_ value.<br/>`_ASSERT_EQUALS_ '"some message"' 'x' '""'`
1. 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__.
### <a name="test-skipping"></a> 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_
```sh
# file: examples/math.inc.
add_generic() {
num_a=$1
num_b=$2
expr $1 + $2
}
add_bash() {
num_a=$1
num_b=$2
echo $(($1 + $2))
}
```
And here is a corresponding unit test that correctly skips the `add_bash()` function when the unit test is not running under the __bash__ shell.
_**Example** -- math unit test_
```sh
#! /bin/sh
# file: examples/math_test.sh
testAdding() {
result=`add_generic 1 2`
assertEquals \
"the result of '${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.
. ./shunit2
```
Running the above test under the __bash__ shell will result in the following output.
```console
$ /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.
```console
$ /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()`, `endSkipping()`, and `isSkipping()`. Once skipping is enabled, it will remain enabled until the end of the current test function call, after which skipping is disabled.

### <a name="getting-help"></a> 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>.
### <a name="zsh"></a> 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.
1. In the unit-test script, add the following shell code snippet before sourcing the `shunit2` library.
```sh
setopt shwordsplit
```
1. When invoking __zsh__ from either the command-line or as a script with `#!`, add the `-y` parameter.
```sh
#! /bin/zsh -y
```
1. When invoking __zsh__ from the command-line, add `-o shwordsplit --` as parameters before the script name.
```console
$ zsh -o shwordsplit -- some_script
```
