How often does `init_code` actually run?

The readme says:

runtests takes a keyword argument that one can use to provide default definitions to be loaded before each testfile. As an example one could always load Test and the package under test.

But is it once per file or once per worker?

Once per file.

[asinghvi17]

Gotcha, thanks. Is there a once-per-worker hook also?

I'm looking at converting GeometryOps to ParallelTestRunner to save my sanity :D, and we have some patches that we eval into other packages to make them fully compliant with GeoInterface, which we use in our tests. Wanted to see if I could avoid the inevitable method overwriting errors :D

Tests are run in isolation, also Enzyme defines functions to be used in all tests: https://github.com/EnzymeAD/Enzyme.jl/blob/0d9ed777e62ea304138ae6483ddc5f7576c02f1a/test/runtests.jl

There currently is no "once per worker" callback.

You could in theory start a new worker for those tests that would only be used for those tests.

I would slightly push back on that and ask why you don't send up an extension

[asinghvi17]

Yeah I might end up setting up a separate package (with some extensions for the overrides) for these test helpers.
