The test can't have TetheringManager as an argument to methods or a field, otherwise the test runner will crash when scanning the class for tests because TetheringManager did not exist in Q. Although testFactoryReset is already skipped on Q, the test runner would fail at initialization time, before starting the run. Use CtsTetheringUtils instead. This ensures that TetheringManager does not have method signatures or members that reference classes that do not exist on Q, so the test runner can scan the class successfully before starting the run.
