[...] > * I only unit test when I only unit test when I have enough of a concept of what I'm trying to build that a test makes sense. Places where I don't test: - Vague prototypes. Tests are a way to describe how something should behave. If I don't yet know how it's supposed to behave, I can't really write a test. Sometimes, you just have to experiment. - Tiny one-off scripts. Often, writing a test for these would require duplicating most of what the script already does, and it's not likely to contain any subtle bugs that you wouldn't find by just running it. - UIs. Mostly because I haven't gotten around to learning Selenium or anything similar. Also because this is the hardest place to automate testing, and the easiest place to manually test.

I guess I start doing things thinking "this will only be a one or two line change" and before I know it, I've added an extra module of code that is largely based on old code, but just different enough to break it. I also find that working in Ruby is counter-productive to working up the mental drive to unit test. This is not me getting all fanatic about ruby (ok, much) but it's true of other dynamic languages. I grew up on Java and C and with that, one tends to get bogged down in so much detail trying to translate behaviour into code, that testing is a nice, high-level view of your program that validates your design to some degree. In dynamic languages, things are already pretty high-level and the tendency here is to believe that writing code correctly every time is about as difficult as writing english sentences with correct grammar each time. A quick run through the spell checker (ruby -wc) and everything's done, right? So yes, it's probably the confidence I get from a dynamic language _after_ C and the like that lets me believe that I've become a brilliant coder overnight because I can suddenly parse strings quickly without worrying about memory leaks, pointers and NUL chars (when I was at university we had a 10% test dedicated to doing just that!). In short, the bug minefields I trained to be extra-worried about no longer exist, so setting up a Unit Test for the 'easy bits' mentally seems like more effort than it's worth. Until it breaks. Part of solving the problem is obviously defining the solution, to me, which is exactly where the test comes! It might be a slightly contradictory way of looking at things, but it's certainly honest!
