This book is the only Rails book that
does test-driven development the entire time, an approach highly recommended by
the experts but which has never been so clearly demonstrated before. Finally, by
including Git, GitHub, and Heroku in the demo examples, the author really gives
you a feel for what it’s like to do a real-world project. The tutorial’s code
examples are not in isolation.
