In hopes of getting myself and my coworkers to adopt automated unit testing methods in future projects, I would like to see a proper example on how it's done. Simple introductionary lessons to unit testing only cover very basic examples and they don't seem to convince anyone of the benefits unit testing can offer. What are some open source projects written in PHP that come with an extensive array of unit tests that are done properly, and can be used as an example of how testing should be done?
Good example of a properly unit tested PHP project?
php;unit testing
Most PHP frameworks these days are unit tests, for a good example of the difference in tools, Zend Framework uses PHPUnit and CakePHP uses SimpleTest. Their repos should be enough to get you started or writing proper unit tests.
