TDD is one of the big issues in the pedagogy of teaching Rails. Teach it from the start (Hartl)? Ignore it (most lightweight intros)? Or find a way to introduce it without intimidating beginners? My approach (in a forthcoming chapter) is to encourage testing literacy, that is, to show beginners how to read test code and run tests, so they will be prepared for further study. Michael Hartl's book is good to read after "Learn Ruby on Rails." I also recommend these three books (the first is the newest): * Aaron Sumner, "Everyday Rails Testing with RSpec" https://leanpub.com/everydayrailsrspec https://leanpub.com/everydayrailsrspec * Noel Rappin, "Rails Test Prescriptions" http://pragprog.com/book/nrtest/rails-test-prescriptions http://pragprog.com/book/nrtest/rails-test-prescriptions * Chelimsky and friends, "The RSpec Book" http://pragprog.com/book/achbd/the-rspec-book http://pragprog.com/book/achbd/the-rspec-book Other resources? How did you learn TDD for Rails?
