- (id)init
{
    if (self = [super init])
    {

        [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(onDidFinishLaunchingNotification:)
                                                     name:UIApplicationDidFinishLaunchingNotification
                                                   object:nil];
        [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(onWillEnterForegroundNotification:)
                                                     name:UIApplicationWillEnterForegroundNotification
                                                   object:nil];
        [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(onDidBecomeActiveNotification:)
                                                     name:UIApplicationDidBecomeActiveNotification
                                                   object:nil];
        [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(onWillTerminateNotification:)
                                                     name:UIApplicationWillTerminateNotification
                                                   object:nil];
    }

    return self;
}

// Notification Observers
- (void)onDidFinishLaunchingNotification:(NSNotification*)notification
{
    NSLog(@"onDidFinishLaunchingNotification");

}

- (void)onWillEnterForegroundNotification:(NSNotification*)notification
{
    NSLog(@"onWillEnterForegroundNotification");

}
- (void)onDidBecomeActiveNotification:(NSNotification*)notification
{
    NSLog(@"::onDidBecomeActiveNotification");
}

- (void)onWillTerminateNotification:(NSNotification*)notification
{
    NSLog(@"onWillTerminateNotification");
}

通知测试用例

    -(void)setup{
        [super setUp];

    mClassObj = [[ClassA alloc]init];

    }

-(void)teaddown{

mClassObj = nil;
    [super tearDown];


}
 -(void)testUIApplicationDidFinishLaunchingNotification {

        [[NSNotificationCenter defaultCenter]postNotificationName:UIApplicationDidFinishLaunchingNotification object:nil];    
        }

期待这样做会有效！

但测试用例失败

-[__NSCFString onDidFinishLaunchingNotification:]: unrecognized selector sent to instance

我试图覆盖上述通知方法的测试用例但它给我的错误说无法识别的选择器发送到实例！

任何人都建议我介绍通知方法的测试用例

@Thanks提前

Answer 1

除了我假设的setUp和tearDown（观察大写字母）的意外拼写错误之外，此代码没有任何问题。我在onDidFinishLaunchingNotification:上放了一个断点，它会被测试触发。

问题是，一个不变的NSString如何潜入那里？
