@mrazauskas Hiya! I cannot use jest.mocked here as it returns jets.MockedObject<typeof Memory> instead of MockedClass. This happens both with @jest/globals and @types/jest (whom I think just copied the implementation from @jest/globals). Any ideas on how we can make jest.mocked work for classes as well?

Yep. I encountered this while working on #12727. That PR is fixing this issue. In general the work on types is finished in that PR, it just needs more tests. In this case these are rather complex ones. Indeed it would be nice to land it for Jest 29. I will try to push forward with the tests, if you can wait with the release for a couple of days (;
