Generally,
expect(*)should always receive the "bare" object i.e. not include any property access. The reason being that in case of a mismatch you want to see actionable debug information from the matcher. Otherwise you almost always end up logging the actual value anyway once it fails. The exception to this rule is if you don't have useful matchers to use.expect(sinonSpy.calledWith(value)).to.equal(true)is problematic for two reasons:Specifically,
DateTimePicker.testallows to select full date end-to-endwas failing after internal refactoring (#24367). It didn't provide actionable information that revealed that the behavior was still correct, but the testing approach problematic. I used this opportunity to refactor the other usages of.calledWith.I don't see how we can safely flag these uses statically
no-restricted-propertieshas no information about the context so it might flag appropriate uses. I think the "no access on the left side of the assertion" is a better heuristic.
