Why do we care about testing this specific behavior if it's so hard to observe it in usage? Should we allow the completed case as a successful test?

        expect(
          task.state,
          anyOf(
            NSURLSessionTaskState.NSURLSessionTaskStateSuspended,
            NSURLSessionTaskState.NSURLSessionTaskStateCompleted,
          ),
        );

At some point my .toString() would throw for certain states so I created a test to catch that. But it might not be worth it.

Should we allow the completed case as a successful test?

        expect(
          task.state,
          anyOf(
            NSURLSessionTaskState.NSURLSessionTaskStateSuspended,
            NSURLSessionTaskState.NSURLSessionTaskStateCompleted,
          ),
        );

That would work but it would miss the intent of the test i.e. to verify that a cancelled test is actually cancelled instead of running to completion (and to verify that toString works correctly ;-))

// the timing to work out (which still isn't a great approach but I can't
// think of a better way).
retry: 5,
);

test('completed', () async {
task.resume();
