The Importance of Unit Tests

I am not a close friend of unit tests. In fact, as a programmer I regard them as annoying. However, when I started to write unit tests for my RS Library classes, I discovered many bugs that I didn’t see before. Those bugs never occurred in production yet mainly because the code was used in a slightly different way and bypassed the buggy parts. Some of the bugs are very stupid so that I wondered how they could ever get into a release.

The experience shows me now that it is important to write unit tests for all classes and their non-trivial methods. This is the only way to write better code. The self-confidence that I have in my own code is not enough. So there will be a lot of unit testing effort within the next weeks. And the next RS library code is most-likely the best-tested code ever.

Nobody is perfect. 😉
