We've just passed more than 1000 unit tests 

In November 2008, me and some fellow colleagues have started working on a new project where we use Test Driven Development to gain a highly maintainable and highly testable system. Today, we have reached our 1000st unit test,  or better, 'specification'. The term Test Driven is a bit misleading since TDD is really a design process, which has nice little granular unit tests as a side-effect. Anyway, we tried to reach this point before Easter, but obviously we were professional enough not to add some dummy tests :-)
