1.5. Acknowledgments

I would like to thank Kent Beck and Erich Gamma for JUnit and for the inspiration to write PHPUnit. I would also like to thank Kent Beck for his JUnit Pocket Guide, which sparked the idea for this book. I would like to thank Allison Randal, Alexandra Follenius, and Barbara Weiss for sponsoring this book at O'Reilly.

I would like to thank Andi Gutmans, Zeev Suraski, and Marcus Börger for their work on the Zend Engine 2, the core of PHP 5. I would like to thank Derick Rethans for Xdebug, the PHP extension that makes PHPUnit's code-coverage functionality possible. Finally, I would like to thank Michiel Rook, who wrote the PHPUnit tasks for Phing.
