What:
Fail tests on
console.errorandconsole.warncalls that are not asserted (i.e. some spy intercepts them).Also adds dedicated
toWarnDevandtoErrorDevmatchers (see changed tests).That help surfacing the intended errors better in tests.
Why:
Otherwise we might add tests that include "missign act" warnings which this library is trying to avoid (e.g. in #1137 the added test would all "pass" without any change to the implementation).
How:
Copy (and adjust) the pattern facebook/react uses.
