Perhaps design by contract is the way forwards? Explicit runtime validation of the flow of data through code at each step in the system. As a frontend developer, I have been moving towards a greater emphasis on functional & integration testing. We're also using scripter here, a test tool that actually compares screen caps with the actual on-screen state of our applications. So a purely visual approach. There's a wonderful world of testing tools out there. I can imagine it's incredibly daunting to a newcomer trying to decide which to pick up and run with, especially with so many job specs specifically asking for "TDD", and now with DHH saying this.
