Not working for modern fake timers (jest v27)

[dan-lee]

wait-for-expect does not work in combination with modern fake timers which are default in jest v27. Probably related issue: callstack/react-native-testing-library#775

I had the same issue. Essentially, wait for expect would always time out no matter what, as if its timeouts were not being advanced.

However, I can fix the issue by doing the following:

beforeAll( () => {
  jest.useFakeTimers(); 
  // OR
  jest.useRealTimers();
} )

for some reason, it fails if I do nothing, but succeeds if I tell jest to use either timer variant. Not sure what's up with that.

It seems like dd272db is probably relevant to what causes this issue? FWIW the beforeAll trick doesn't seem to work for me.
