Rerun setupFiles in watch mode

[Maxim-Mazurok]

Clear and concise description of the problem

I'm mocking http requests using msw and as suggested in vitest docs I'm putting my handlers in setup files.
While running vitest in watch mode I want to edit handlers and to have these changes applied before rerun of tests. However changes to setup files aren't being picked up in watch mode even if I forcefully rerun all tests. I need to restart vitest for changes to apply.

Suggested solution

Rerun all setupFiles in watch mode, or add an option to do that on a per-file basis.

Alternative

An alternative is probably using something like nodemon and then run vitest --run, but it probably isn't really worth the trouble, hopefully, I won't have to make many changes to mocked API once it's done.

The setupFiles will be run before each test file and not changes often, what about trigger server restart when setupFiles content changed just like config file, is it a good implementation ?

This does sound better to me. I don't expect these files to change as much as the actual tests during active development, so rerunning them every time might be a bit of a waste, so your suggested optimisation does sound good to me.

I think we can just add setupFiles to forceRerunTriggers. it will rerun every test, when file changes.

Great! Thanks for your advice, I will try to solve it.

I'm not sure this will help... As I've mentioned in OP even when I rerun all the tests forcefully by pressing a - changes in setup files aren't picked up. Maybe this rerun isn't being forceful enough tho, not sure about the inner workings.

Aha, I am not really make sure, but I test it in this demo, I get the same result with you, the globalThis.a didn't change as expected when I change it in watch mode. I will read codes tomorrow or the day after tomorrow to get the exact reason.
