Add tests for `GetInterfaceMap` on static interface methods #90518

hamarb123 · 2023-08-14T12:39:21Z

Fixes #90351.
Includes the currently single failing case from the comment #90351 (comment) - therefore I propose that all (/ or at least most) of the combinations are useful since they actually found a bug.
This probably can't be merged until it's fixed, or maybe that just needs to be disabled for now, but that's alright lol.

The failing case is the case which checks C2Implicit<string>'s implementations of I1<string>.G<T>. Previously, until recently when some other unrelated (to this) changes to static interface methods were made, many more cases were broken.

Related failure issues, which have had their tests disabled:

maybe that just needs to be disabled for now, but that's alright lol.

I would recommend disabling the test against a new issue.

hamarb123 · 2023-08-14T23:40:34Z

I would recommend disabling the test against a new issue.

Is there a proper way to do this, or do I just need to skip the test manually? I ask because it's using an interesting setup, where it returns an IEnumerable<object[]> using yield as data for a [Theory]; presumably there's no way to do an [ActiveIssue] for just 1 of those cases?

jkotas · 2023-08-15T00:16:47Z

Comment out the failing case and add // [ActiveIssue("https://github.com/dotnet/runtime/issues/12345")] in front of it.

hamarb123 · 2023-08-21T11:04:03Z

I also need to exclude some tests on mono by the looks of it (mono and coreclr seem to behave differently in some of the cases?), I will add an [ActiveIssue] for that when I make an issue for that too.

• Would be good to test these anyway • Added to see if the failures on mono are with static interface methods only, or to do with default implementation methods

• Haven't opened an issue for this yet - will follow up with an issue & commit to add the issue link

Looks great to me, thank you!

hamarb123 · 2023-08-23T21:57:26Z

If there is nothing else to do, please flip the PR from Draft to Ready to review.

I haven't opened the other issue yet, if you're alright with merging it without that issue then feel free, or if you wanted to open it that would be great since I'm struggling to run mono locally and therefore write a useful reproduction for the issue with specifics of which cases fail and what happens instead and what's expected.

jkotas · 2023-08-23T22:03:04Z

For the tracking issue, it is fine to just link to the test that is disabled. You do not need to go the extra mile to extract the disabled test into a small repro.
