ios - 如何测试 AFNetworking

Question

*编辑 - 我最初想使用 Nocilla 测试 AFNetworking，但最终使用 OHHTTPStubs 来完成这项工作。我已经使用 OHHTTPStubs *

回答了下面的原始问题

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原理。因此，我需要模仿 AFNetworking 中的 HTTPRequestOperationWithRequest: 调用。 Nocilla 似乎是执行此操作的一个选项(比 OCMock 更合适)。我已经查看了 the github page它处理 Nocilla 和 AFNetworking 但我不确定如何将它应用于我的问题 - 语法不是很熟悉。

• 所以我想知道是否有人可以给我一些提示，告诉我在这种情况下如何使用 Nocilla？
• 此外，必须将 Kiwi 与 Nocilla 一起使用吗？

    // 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 OHHTTPStubs 解决了这个问题。可以通过 AFNetworking 轻松返回模拟对象，排除某些请求并改变响应/请求时间。有据可查here .这里还有 github page .像这样删除 stub :

[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;

}
