By Rick Mugridge and Ward Cunningham (yes, the c2-guy and wiki-inventor), Prentice Hall 2005. A very convincing book - if you don't yet know or use the FIT acceptance testing framework (plus its comanion FITNESSE, the acceptance-testing-wiki), this book will surely motivate you to give those two a try! If you never had the opportunity to use FIT in a real project - that'l surely change. The book, brilliantly structured, well written, carefully edited, contains starting points for many projects to come. Five stars!
My next quest will be the evaluation of the different FIT implementations - as a few of my current projects are non-Java - but that'll be covered in a future posting.
