如何测试AFNetworking

Question

>*Edit - 我最初想使用 Nocilla 测试AFNetworking，但最终使用 OHHTTPStubs 来完成这项工作。我已经回答了下面的原始问题，使用 OHHTTPStubs *

原始问题：

我想测试我们应用程序的 APIClient - 下面详细介绍了需要测试的方法之一的基本内容。所以我需要模仿AFNetworking的HTTPRequestOperationWithRequest:电话. Nocilla似乎是执行此操作的一种选择（比OCMock更合适）。我已经查看了处理Nocilla和AFNetworking的 github 页面，但我不确定如何将其应用于我的问题 - 语法不是很熟悉。

• 所以我想知道是否有人可以给我一个提示，在这种情况下我如何使用Nocilla？
• 另外，必须将Kiwi与Nocilla一起使用吗？

提前致谢:)

                                         limit:(NSNumber *)limit

                               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;
}

我最终使用另一个库解决了这个问题，OHHTTPStubs .人们可以通过AFNetworking轻松返回模拟对象，存根某些请求并改变响应/请求时间。这里有很好的记录。这里也是github页面。像这样删除存根：

[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;
}
