In celebration of the 10th anniversary of Selenium, the guys from Thoughtworks created a small ebook available for free:
It's been 10 years since Selenium was born and the industry has changed tremendously since then. In honor of Selenium's first decade, we put together some our greatest hits and new pieces on software testing.
How has testing evolved in the past decade? How do we adapt to the new challenges that mobile testing has to offer? Can testing in an agile environment lead to faster feedback?
Download this free e-book and read more about the big developments in testing methods and tools, while looking closely at the advent of mobile testing and what the future holds for QAs.
The book can be downloaded here: http://info.thoughtworks.com/ebook-agile-software-testing.
