For those that may not have read any of my previous postings on the subject the goal of this software is to extend the functionality of PHPUnit to allow using seed data to put a given database into a known state prior to executing each test. It also provides an easy mechanism to compare database contents with an expected dataset.
Mike has just completed the initial feature set for his project - more or less a port of DBUnit over to PHP. The post includes not only details about this initial release but also code that demonstrates its use. In his example, it's used to validate that a bank account has been created properly by comparng database information before and after the insert.
