Testilence is an open-source unit testing library written in PHP 5 for programs written in PHP 5. It is published under the MIT license which means you are free and welcome to use it in any way. Although it is similar to other JUnit-inspired unit testing libraries, Testilence is written with emphasis on what's useful, not what's usual. That said, most clever ways of doing useful things for unit test authors and users have already been discovered. Testilence combines original ideas with the best features found in different unit-testing toolkits into a coherent set.
