What:
Adds tests for
waitFor
,waitForElementToBeRemoved
andfindBy
across all supported timer implementations (real timers, jest legacy fake timers, jest modern fake timers).Why:
These offer a more granular coverage that's required for #937.
The new tests are also the only tests that would trigger a missing act warning if we were to remove the
asyncWrapper
.How:
Backport tests from #937 and convert the class component to a function component. With a class component we'd still not get a missing act warning.
