shunit2
SHUNIT2(1) SHUNIT2(1)
NAME
shunit2 - A unit test framework for shell scripts
SYNOPSIS
shunit2 unitfile
DESCRIPTION
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.
You can either run shunit2 directly from the commandline and specify the unit file or directly source the shunit2 executable.
If you directly execute shunit2 and don't specify a unitfile shunit2 assumes a empty testfile and will return without an error message.
EXAMPLE
Simple script to test if 1 equals 1
#! /bin/sh
testEquality()
{
assertEquals 1 1
}
# load shunit2
. shunit2
Execute shUnit2 unit tests directly from the commandline
shunit2 /path/to/unit/file
OPTIONS
shunit2 does not support any commandline options at all. You can either source shunit2 to execute your unit tests or directly run shunit2
as a commandline script.
SEE ALSO
For more information see http://code.google.com/p/shunit2/ or have a look at the installed documentation in /usr/share/doc/shunit2/
