Giorgio Sironi has posted a quick book review of a recent publication from Packt Publishing: "PHPUnit Essentials". The author, Zdenek Machek, has written a "practical guide featuring a step-by-step approach that aims to help PHP developers who want to learn or improve their software testing skills."

The first thing that struck me about the book was the breadth of subjects: you start from mocks and command line options, to get even to Selenium usage. [...] There is a bit of what may seem outdated information in the book such as how to perform a PEAR-based installation, but it's identified as such (PEAR being deprecated and dismissed by the end of the year.) Another seemingly outdated tool is Selenium IDE, but once upgraded with a formatter for Selenium2TestCase like explained in this book it becomes usable again. This kind of advice demonstrates the real world experience of the author and makes you trust the content.

He suggest that the book is more for those just starting out on their testing journey and wanting to get up to speed quickly with a wide range of tools, not just the base PHPUnit handling.
