I once saw a talk from Brian Kernighan who made a joke about how in three weeks Ken Thompson wrote a text editor, the B compiler, and the skeleton for managing input/output files, which turned out to be UNIX. The joke was that nowadays we're a bit less efficient :-D

Otoh: I got react to run my tests without any warnings today.

If I write a bunch of tests for new code, and all of them pass on the first attempt, I'm immediately suspicious of a far more egregious bug hiding somewhere…

Where feasible, I like to start a suite with a unit test that validates the unit's intended side effects actually occur, as visible in their mocks being exercised.

/bin/true used to be an empty file. On my desktop here, it's 35K (not counting shared libraries), which is an asolute increase of 35K and a relative increase of ∞%.

"never trust a test you've never seen fail." has kept me honest on more than one occasion.

Sure. For Patreon subscribers at the $5/month tier and up, I also have a course on making integration ("e2e", "functional") tests more maintainable by eliminating side effects.
