When you do, do you write unit tests? Do you agree that there are benefits to using test-driven development? I stopped writing tests on my code base for bad reasons, but started again for good ones. The experience has allowed me to demonstrate in practice the impact it can have on your code base when you don’t test, and also when you do. This talk, based on simple practical examples, explains exactly why unit tests, a TDD approach and pairing can make all the difference to your code.
