no-ignored-test-files hangs with ava@4.0.0-alpha.1

[ninevra]

With ava@4.0.0-alpha.1 installed, running the no-ignored-test-files rule on any AVA test file causes eslint to hang indefinitely.

With ava@3.x, or with "no-ignored-test-files": "off", everything's fine.

Minimal reproducible example.

Thanks. This is a bug in AVA itself. This rule requires access to the active AVA configuration, which is now resolved asynchronously (for ESM support). To make that work with a synchronous ESLint we spin up a worker thread and synchronize state using shared memory. Unfortunately the worker thread is not loading the right file, but that error can't be communicated because we're waiting for the shared memory to change…

I'll add a timeout for config resolution and fix the code.

@ninevra this is now out as Alpha 2.
