Tests retaining reference count

Question

It seems octest doesn't decrement reference count for instances created within a test

- (void)test_That_TaskFetcher_is_Invoked_from_tasksDownloaded {
    InboxViewController *vc = [[InboxViewController alloc] init];
    id fetcher = [OCMockObject mockForClass:[TaskFetcher class]];
    [vc setTaskFetcher:fetcher];
    [[fetcher expect] fetchTasksfromManagedObjectContext:OCMOCK_ANY
                                           withPredicate:OCMOCK_ANY
                                    WithBlockForEachTask:OCMOCK_ANY
                                        WithFailureBlock:OCMOCK_ANY
                                      WithNoResultsBlock:OCMOCK_ANY
                                     WithCompletionBlock:OCMOCK_ANY];
    [vc tasksDownloaded];
    STVerify(fetcher);
}

vc has a [NSNotificationCenter defaultcenter] listener on it. The listener on this vc instance is getting invoked from other tests.

why???

Did you set your test target to use ARC? – Jon Reid May 31 '13 at 05:37 — Jon Reid, May 31 '13 at 05:37
Does this happen for failing test, passing test, or both? – Jon Reid Jun 05 '13 at 18:49 — Jon Reid, Jun 05 '13 at 18:49

...are you removing the notification observer from your view controller? Calls to addObserver: need to be matched with a corresponding removeObserver:, otherwise you can run into these sorts of issues.

i'm removing the observer on `dealloc`, but dealloc is never getting invoked – Zayin Krige May 25 '13 at 11:25
also, notification center observers are weak references, so it wouldn't lead to retained reference count – Zayin Krige May 25 '13 at 11:26
