如何测试AFNetworking

Question

* Nocilla编辑--我最初想用Nocilla测试，但最终使用 OHHTTPStubs 来完成这项工作。我使用OHHTTPStubs *回答了下面的原始问题

原题：

我想测试我们的应用程序的APIClient --需要测试的方法之一的基本原理如下所示。因此，我需要模拟来自AFNetworking的AFNetworking调用。Nocilla似乎是这样做的一个选项(比OCMock更合适)。我已经检查了github页面，它处理了Nocilla和AFNetworking，但是我不知道如何将它应用到我的问题上--语法不是很熟悉。

• 所以，我想知道是否有人能给我一个提示，说明我如何在这种情况下使用Nocilla？
• 另外，必须将Kiwi与Nocilla结合使用吗？

(预先谢谢:)

                                     startTime:(NSDate *)date
                                         limit:(NSNumber *)limit
                                     pastLimit:(NSNumber *)pastLimit

                               completionBlock:(void (^)(NSArray *broadcasts, NSError *error))block {

    // Some setup here

    NSURLRequest *request = [self requestWithMethod:@"GET" path:path parameters:params];

    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，我使用另一个库OHHTTPStubs解决了这个问题。您可以通过AFNetworking轻松地返回模拟对象，删除某些请求&更改响应/请求时间。这是一个很好的文档这里。这里还有github页面。存根被移除如下：

[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;

}
