When I wrote the “Selenium Simplified” book, I was trying to teach Java, at the same time as Selenium-RC.
I decided that the next time I write a book I would be more focused, so I’ve just made public the fact that I’m writing a book called “Java For Testers”.
You can find more details on the book web site’s and blog:
The book is in beta, so I’m still writing it. This also means that if you buy it early you can get hold of it at a reduced price. The price will increase the closer to production ready it becomes.
