With unit testing becoming more and more prevalent in development of online applications (especially PHP), it's good to see some of the frameworks giving their users as much information as possible. The symfony project has done just that as a part of a larger book on the framework.

You're probably curious to see if what we wrote in this book is really helpful and practical. So we decided to offer you a sample of the book, in PDF format, and that's precisely Chapter 15 about units and functional tests.
