测试保留参考计数

Question

似乎octest不会减少测试中创建的实例的引用计数

- (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上有一个[NSNotificationCenter默认中心]监听器。此vc实例上的侦听器将从其他测试中调用。

为什么???

...您是从视图控制器中删除通知观察者吗？致addObserver:的电话需要与相应的removeObserver:匹配，否则您可能会遇到这类问题。
