Recently, some of my projects rely heavily upon tests with selenium. Some books about selenium are collected and listed here for reference.
- An Introduction to Testing Web Applications with twill and Selenium (2007)
* A simple introduction to how to use twill and selenium in entry level. It's really old and outdate. Web environment and tools have changed a lot since it's published.
- Selenium 1.0 Testing Tools: Beginner’s Guide
* A beginner's guide to using Selenium to record, tweak and replay test scripts.
