如何测试AFNetworking

Question

* 编辑 - 我原本想用Nocilla测试AFNetworking，但最终使用OHHTTPStubs来完成这项工作。我已经回答了下面原来的问题，使用OHHTTPStubs *

原题：

我想测试我们的应用程序的APIClient - 其中需要进行测试详述如下方法之一的梗概。所以我需要模仿来自AFNetworking的HTTPRequestOperationWithRequest:电话。 Nocilla似乎是一个选择来做到这一点（比OCMock更适合）。 我已经签出the github page其中涉及Nocilla和AFNetworking但我不知道如何将其应用于我的问题 - 语法不是很熟悉。

• 所以我想知道如果有人可以给我一个暗示，我可能会在这种情况下使用Nocilla？
• 此外，必须使用Kiwi与Nocilla？

感谢提前:)

    AFHTTPRequestOperation *operation = [self HTTPRequestOperationWithRequest:request success:^(AFHTTPRequestOperation *operation, id responseObject) { 

    NSError *error; 

    NSDictionary *responseDic = [self parseResponse:responseObject error:&error]; 

     if (error) { 
      if (block) { 
       block([NSArray array], error); 
      } 
      return; 
     } 

     // Parse the response object here 

     if (block) { 
      block([NSArray arrayWithArray:broadcastsOutput], nil); 
     } 

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 

    if (block) { 
     block([NSArray array], error); 
    } 
    }]; 

     [self enqueueHTTPRequestOperation:operation]; 

     return operation; 

}

最后我用另一个库，OHHTTPStubs解决这个问题。人们可以通过AFNetworking轻松返回模拟对象，根据某些请求提供&差异响应/请求时间。 这是有据可查的here。这里还有github page。存根被删除这样的：

[OHHTTPStubs removeStub:stub]; 

下面是一些示例代码：

// A mockJSON file is loaded here 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"sampleJSON18.json"]; 
NSData* data = [NSData dataWithContentsOfFile:filePath]; 
NSError* error = nil; 
id mockJSON = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error]; 

//*** stub out AFNetworkingRequestOperation and return custom NSDictionary "mockJSON", in order to see how it is handled 
id<OHHTTPStubsDescriptor> stub = nil; 
stub = [OHHTTPStubs stubRequestsPassingTest:^BOOL(NSURLRequest *request) { 
    return [[request.URL path]isEqualToString:@"/v1/epg/packages/59/broadcasts"]; // this means that any request which is equal to the above string is stubbed, return YES to stub *all* requests 
} withStubResponse:^OHHTTPStubsResponse*(NSURLRequest *request) { 
    // The `stubbing` procedure occurs in this block. 
    return [[OHHTTPStubsResponse responseWithJSONObject:mockJSON statusCode:200 headers:nil] requestTime:1.0f responseTime:5.0f]; // one can vary the request/responseTime here 
}]; 

stub.name = @"getChannelsWithBroadcastsForDay"; 

AFHTTPRequestOperation *operation = [self HTTPRequestOperationWithRequest:request 
                    success:^(AFHTTPRequestOperation *operation, id responseObject) 
    { 
     // The response object is now the mockJSON object, i.e. the original request is stubbed out 

     } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     // handle failure 
    } 

     }]; 

    [self enqueueHTTPRequestOperation:operation]; 
    return operation; 

}
