do you expect people will want to call these separately
(resetBehavior/clearLogs)? ow, make them private?

I'd check also that:
log.logs.every((e) => e.mockName == 'm2' || e.mockName == 'm3'));

tests/lib/unittest/mock_test.dart:626: m2.clearLogs();
I'd also check that calling m1.clearLogs() again is a noop.

Yes. For example, I may want to set up the behavior once with 'alwaysReturn'
actions, then do some tests, verify, clear logs, do more tests, verify, etc. So
I do think they are orthogonal.
