嘲讽预期为代表

有什么不对下面的猕猴桃/ iOS的模仿期待？

长版的问题：

我想写的猕猴桃，iOS的测试一个简单的类来处理一个NSConnection连接。为了测试这个类处理来自NSConnection的回调，我发送NSConnection通常所做的委托方法。我有一个班级的代表，可以将数据发回给使用我班的人。为了测试我的类，我必须注入一个模拟委托，然后检查我所需的方法是否被调用。就这么简单:)

我对猕猴桃测试代码：

//Some ivars declared elsewhere: 
testString1 = @"asd323/4 d14"; 
testString2 = @"as98 /2y9h3fdd14"; 
testData1 = [testString1 dataUsingEncoding:NSUTF8StringEncoding]; 
testData2 = [testString2 dataUsingEncoding:NSUTF8StringEncoding]; 
mockURLRespons = [NSHTTPURLResponse mock]; 
int value = 11111; 
id mockDelegate = [KWMock mockForProtocol:@protocol(SharepointConnectionDelegate)]; 
communicator = [[SharepointCommunicator alloc] init]; 

it (@"should send recieve data back to delegate2", ^{ 
    [communicator setDelegate:mockDelegate]; 
    [mockURLRespons stub:@selector(statusCode) andReturn:theValue(value)]; 
    [(id)communicator connection:niceMockConnector didReceiveResponse:mockURLRespons]; 
    [(id)communicator connection:niceMockConnector didReceiveData:testData1]; 
    [(id)communicator connection:niceMockConnector didReceiveData:testData2]; 
    [(id)communicator connectionDidFinishLoading:niceMockConnector]; 

    [[mockDelegate should] receive:@selector(connectionDidSucceedWithText:andStatus:) withArguments:[testString1 stringByAppendingString:testString2],theValue(value),nil]; 

});

在我SharepointCommunicator.m：

-(void)connection:(NSURLConnection *)aConnection didReceiveResponse:(NSURLResponse *)response { 
    if (connection != aConnection) { 
     [connection cancel]; 
     connection = aConnection; 
    } 
    responseData = [[NSMutableData alloc] init]; 
    statusCode = [(NSHTTPURLResponse*)response statusCode]; 
} 

-(void)connection:(NSURLConnection *)aConnection didReceiveData:(NSData *)data { 
    if (aConnection != self.connection) 
    return; 
    [responseData appendData:data]; 
} 

-(void)connectionDidFinishLoading:(NSURLConnection *)connection { 
    NSString *txt = [[NSString alloc] initWithData:responseData encoding: NSASCIIStringEncoding]; 
    NSLog(@"Statuscode: %i", statusCode); 
    NSLog(@"Data is: %@",txt); 
    [delegate connectionDidSucceedWithText:txt andStatus:statusCode]; 
    [self.connection cancel]; 
    self.connection = nil; 
}

此代码的工作和是正确的。使用检查点进行调试显示它按预期进行。 statusCode的值是11111.而txt是testString1 + textString2。仍然在测试的最后一行失败，出现以下错误：

error: -[kiwiSharepointCommunicatorTest Sharepointcommunicator_AStateTheComponentIsIn_ShouldSendRecieveDataBackToDelegate2] : 'Sharepointcommunicator, a state the component is in, should send recieve data back to delegate2' [FAILED], mock received unexpected message -connectionDidSucceedWithText："asd323/4 d14as98 /2y9h3fdd14" andStatus：11111 
Test Case '-[kiwiSharepointCommunicatorTest Sharepointcommunicator_AStateTheComponentIsIn_ShouldSendRecieveDataBackToDelegate2]' failed (3.684 seconds).

删除测试中的最后一行仍然会生成相同的错误。我想我得到的理解：withArguments：错了..

我假设它与猕猴桃的参数匹配有关。也许这场比赛是在指向对象的指针？这就是为什么字符串不匹配，即使它们包含相同的字符串？或者它可能无法处理非对象匹配，如int ... – Sunkas 2012-04-17 08:14:10

我有类似的问题，我的代理将字符串传递给它的代表（模拟） – quantumpotato 2012-04-20 15:51:10

你必须调用[[mockDelegate should] receive...之前调用connectionDidFinishLoading准备mockDelegate它是关于接收消息。

现在是我编写了这段代码的一段时间，但我很确定你是对的。我做了一个更小的方式重新编码，然后让它恢复工作。可能是因为现在的预期是前期设定的。 – Sunkas 2012-10-08 12:44:48
