Nice simple article describing a technique to parallelize tests and a quick fix to an issue blocking it.

It is interesting to observe the time that things take in various environments. I worked in ad tech previously with lots of offline big-data jobs. Test completion took a few minutes even fully parallelized. Now I work in HFT and our test suite completes on an M1 Max in 21 s and it's got higher coverage.

The situations aren't really comparable. But it's interesting to see the different baselines.
