About the Author

Michael Lively has worked in a variety of roles in the software development industry for 12 years, from developer to architect and now a software development director. He has worked on a variety of different projects and a variety of different technologies over that time, from small home-grown sites serving a handful of regular users to large enterprise platforms serving millions of consumers. In addition to his professional work, he has been an active member of the PHP open source community. Some of his contributions include the database extension for PHPUnit and more recently an alternative mocking framework for PHP called Phake.

I would like to thank everyone who, over the years, has given me opportunities to work in and with the technology industry. From my schooling to the present day I have had the fortunate blessing of meeting some of the most gifted and knowledgeable folks in the IT industry. Specifically, I would like to thank Sebastian Bergmann who introduced me to unit testing and provided me great opportunities to contribute back to the community. I would also like to thank Brian Feaver and Adam Englander. Both are fantastic co-workers and gave me lots of great feedback when I discussed topics for this book with them.

Last but certainly not least this journey called life would not be nearly as complete without my girls. I would like to thank my wonderful wife Sharon and my fantastic girls Trinity, Hannah, and Gracelyn. Their patience and willingness to chase my goals with me has made all the difference in the world.
