Target audience: Software Developers
Urs’ comment: As the back cover says, this is the definitive guide to test automation. If you really want to know all you can know about unit testing then this is your book.
However, this book does not come for free. Reading is hard because it’s not exactly written like a block buster. It took me over six months of hard work to get through it (even with skipping some sections). Therefore, if you want to learn unit testing then you better start with The Art of Unit Testing – with Examples in .NET by Roy Osherove (see below).
In the end, this book surely is THE ultimate book to look up all things relevant in unit testing.
