alt Hacker NewsI don't think testing the product alone is good enough, because when you give it tests it has to pass it prioritizes passing them at the expense of everything else — including code quality. I've seen it pull in random variables, break semantic functions, etc.
Oh, no. I test. Each. and. Every. Step.
I use a test harness, and step through the code, look at debug logs, and abuse the code, as much as possible.
Kind of a pain, but I find unit tests are a bit of a "false hope" kind of thing: https://littlegreenviper.com/testing-harness-vs-unit/
