> I could test that with broad tests, but doing that in a large system means that you end up with a combinatorial explosion of tests, or (more likely) hidden gaps in your tests. Extremely well put. This maps exactly to my experience when moving from unit tests to the layer above. Test are taught exactly like “draw the rest of the fucking owl” meme, and I’ve never seen them actually hold up to the nice and tidy “hello word” tests that you see in demos. You’re actually trying to tackle the reality of gritty and ugly software systems, and it’s very refreshing to see, because it may just work. It’s gonna take a while to see if it holds up, but so far I am really excited.
