Description
The test suite runs rather slow, and I was wondering whether it is possible to speed it up.
I’ve tested different variants on MBPs from 2010 and 2008 (sorry, don’t have more recent hardware available atm):
| CPU | current state | no typescript | jasmine instead of jest, no typescript |
|---|---|---|---|
| Core2Duo | 4m20.332s | 0m51.636s | 0m27.554s |
| i7 (2010) | 2m1.904s | 0m24.786s | 0m23.579s |
- The biggest offender is TypeScript, so the first question is: Do the tests really need to use typescript?
- The QuickCheck-style tests (with jasmine-check) take their time. I think it might be worth considering moving those to a separate suite. That way, there’d be a really fast running test suite that gives quick feedback (< 5 seconds) during development, and the jasmine-check-suite that can be run on occasion and by CI.
- I don’t know why jest is slow on old hardware, but I guess that matters only to me when working on my ancient machine.
