SimpleTest 
is a unit testing
framework for PHP
similar to the xUnit frameworks available for other languages. Whilst SimpleTest provides a mock-objects implementation it was (at the time
that I begun this project) still quite incomplete. Because of this, I developed an alternative mock-object framework that complements
SimpleTest nicely, whilst adding support for PHP5 semantics (such as interfaces) and providing a more flexible API than SimpleTest.
A list of the biggest features:
- Record and replay model for expectations.
- Expectations can be set based upon argument matching and number of call repetitions.
- Actions can be set upon method calls to return specific values or throw exceptions.
