Development is hard! Well, I should really say that good development, getting things to work properly, efficiently and reliably, is hard. Even the best developers make mistakes and introduce bugs or unexpected behavior. It doesn’t matter if you’re carrying out that software development on Windows with powerful IDE software which catches a lot of the mistakes before they reach your users – you can still get problems which seep through, potentially disastrously.
Test-driven development is a technique which tries to stop that particular problem in its tracks by employing methods where the tests of the code’s desired behavior and functionality are written first and then the code created to make those tests pass. Developers who use test driven development say they find it leads to much improved quality of the code’s final product.
In this video, Embarcadero Technology partner and MVP Serge Pilko talks to fellow MVP Jens Fudge about the pros and cons of test-driven development.
