Two book reviews

Test driven development: by example (Kent Beck)

An easy read (also quite thin). Didn't learn too much new but the later sections/appendixes that list refactoring patterns were quite interesting (I hadn't read about them before but I sure recognised some of them!).

Growing object-oriented software, guided by tests (Steve Freeman, Nat Pryce)

Sometimes a tad theoretic, sometimes a tad too practical. The automated testing of the user interface (reading value of label for example) is too extreme for my tastes but it was impressive to see it done. Great book to learn about mocking and mock objects! After all, Steve and Nat helped build jmock. It also expanded my ideas of TDD. I was to focused on unit tests but this book broadened my scope to include tests at every level and not to get too hung up with terminology.

Test driven development workshop

The company I'm currently working for is interested in starting up with Scrum but finding it difficult to make headway. As a start, they've decided to start familiarizing themselves with some of the agile and scrum elements. For example, they asked me to prepare a Test Driven Development (TDD) workshop for them so that they could gain a better understanding of what the benefits are.

Not being an experienced TDDer either, I googled the great StingCalculator Kata by Roy Osherove and prepared this. I found this to be a great kata for TDD because:
1) it allows for incremental building of tests and functionality (triangulation)
2) it quickly demonstrates the value of refactoring and reuse of code
3) you can easily hit red when going for the Obvious Implementation (fast) and so it forces you to go back to Fake It and Traingulation (slow).

I also made a short introduction to TDD and this Kata.
