Irfan's Test

A super fast bare minimum testing suite

Require it using composer:

$ composer require --dev irfantoor/test

How to use test?

$ cd github/yourname/yourproject/

# require it as --dev dependency inside your project
$ composer require --dev irfantoor/test

# you can use the following syntax in the base folder of your prject:
$ ./vendor/bin/test

# Note: By default it will try to locate the test classes in the tests folder and will
# execute all the unit tests.

Usage with an example

An example php file, is included here to serve as a fast example of how you can use the unit tests.

Filename: examples/MyClassTest.php Note: filename must match with the test class name, i.e. the filename implies that the test class defined int the file is: MyClassTest

You can try running the test, by increasing the verbosity level, which will add some additional information in a colorful way.

# with no verbosity level
$ ./test examples/MyClassTest.php

# with verbosity level 1
$ ./test -v examples/MyClassTest.php

# with verbosity level 2
$ ./test -vv examples/MyClassTest.php

# with verbosity level 3
$ ./test -vvv examples/MyClassTest.php

# i and f options have been added to facilitate the development
$ ./test -vvv -i ExceptionThrownWithMessage examples/MyClassTest.php
$ ./test -vvv -f exception examples/MyClassTest.php

NOTE: The values provided to the options -i and -f are case-insensitive
