If we were doing test-driven development we’d start with a failing spec and then write code to make it pass and this is one of the advantages of test-driven development as it ensures that your tests are working. In our application we’ve jumped straight to a passing test as the implementation is already in place. When adding tests for existing code it can sometimes be worth deliberately breaking something in the code to ensure that the test then fails and then fixing it again.
