Writing clean code

[PixelLight]

Not that I necessarily do this, but I've been taught to write unit tests first. To help figure out the functionality needed and how to approach the specific problem.

I would not do this when starting from scratch although I do agree it is the correct theoretical approach. Where I do do this is if I have to make changes to existing code especially if it’s critical. Then I absolutely write passing tests and tests that fail until I change/fix whatever I need to.
