PHPUnit API
There are several types of asserting API provided by PHPUnit. In our examples
we used ones like assertTrue(), assertEquals(), assertFalse(), and
assertNotNull(). However, there are dozens more. The function names are self
explanatory. The following table is taken from the book PHPUnit Pocket Guide
written by Sebastian Bergmann himself and published by O'Reilly. The book is made

The latest version of this book is currently available at http://www.phpunit.de/
pocket_guide/3.0/en/index.html.
The following table shows all the assert functions possible with PHPUnit:
