Looking for ideas for TDD webcast next week

I’m currently scheduled to take part in a TDD webcast next Wednesday, and I’m looking for advice about what to cover. We’ve already done a basic, “This is TDD” webcast in May or so, so I’m looking for what Chapter 2 should be.

Ideas I’ve had include

  • TDD Around the Edges — how to TDD code that touches APIs, servers, databases, etc
  • TDD and its affect on Architecture — how TDD affects the architecture of a system

Whatever we do, it has to be coverable in roughly 50 minutes of talking plus demos.

Any ideas? You name it, and we’re likely to do it!
