Presenters: Dave Cleal & John Daniels (Syntropy)

Style: Workshop

Duration: 90 minutes

Dave & Johns thesis is that TDD is a good thing, provided you write the correct unit tests. Writing every test you can think of is apprentice behaviour: journeymen tend to write less tests but sometimes in the wrong way: masters are perfect.

They'll start by describing some tests they've written that were clearly the wrong thing. They'll encourage heckling and discussion. Then they'll invite the audience to split into groups and identify other tests they've written that could have been better structure. The focus will be on the anti-patterns that describe the unhelpful code. Each group will then present their best (worst?) examples to the rest of the workshop.

Prerequisites: Developers will need experience of TDD
