I think Thoughtbot did a nice job of explaining TDD in this 1 hr video (playback speed was increased). Its part 1 or part 2 I forget. My favorite part is when Josh Clayton excitedly said "Writing our tests is the fun part! Failed tests tell you what to do next!". It was a sort of an aha moment in Rails for me where everything came together. Moreover, the emphasis was on integration testing (Capybara/Rspec), which I could more easily grok and see the importance, then say unit testing. Here's a link to the Integration Testing Videos and I hope they could publish this for every one to see freely. I personally feel this was an eye opener to me, and could possibly be one for others as well. https://upcase.com/test-driven-rails https://upcase.com/test-driven-rails P.S. I want Thoughtbot to make more real-world applicable quick-cut videos (e.g. Proper usage of the GH PR/Merge Model would be great). The weekly iteration is interesting, but its too conversational. I like rehearsed sentences that quickly convey the knowledge to me. That's the missing piece for me to subscribe.
