一个超级快速的最小化测试套件

使用composer要求它

$ composer require --dev irfantoor/test

如何使用测试？

$ 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.

使用示例的用法

以下包含一个示例php文件，用于快速展示如何使用单元测试。

文件名：examples/MyClassTest.php 注意：文件名必须与测试类名称匹配，即文件名意味着在文件中定义的测试类是：MyClassTest

<?php
