Practical Testing PHP Applications with Selenium
Sebastian Schürmann - Practical Testing PHP Applications with Selenium:
"All in all Selenium provides a simple way to execute Acceptance Tests on Web Applications and as soon as you have a remarkable test suite, covering the basic steps of your Application you will find out that it eases developer life and daily usage lowers the number of sideffects (bugs) that pop up because of changes to the codebase. Its a real timesaver, if you know how to use it, so get some practice."
