this book is terrible and I am not sure whay it has been recommended to be honest, its padded out with massive text and screenshots per page, it appears to be just a list of vendor tools and most of the information presented can be obtained from the internet.  to be honest I wouldn;t really bother with this unless you are brand new to software testing.  It's suitable proabaly for junior testers with bad eyesight, do not waste your money on this.
