几个事情要评论你的问题.
首先,您的代码很难测试,因为它直接创建了AFHTTPClient.我不知道是不是因为它只是一个样本,但是你应该注入它(参见下面的示例). @H_403_4@其次,您正在创建请求,然后是AFHTTPRequestOperation,然后将其排入队列.这很好,但您可以使用AFHTTPClient方法getPath获取相同的参数：参数：success：failure：.

@H_403_4@我没有那个建议的HTTP stubbing工具(Nocilla)的经验,但我看到它是基于NSURLProtocol.我知道有些人使用这种方法,但我更喜欢创建自己的stubbed响应对象,并模仿http客户端,就像在下面的代码中看到的那样.

@H_403_4@Retriever是我们要测试我们注入AFHTTPClient的类别.
请注意,我直接传递用户和事件ID,因为我想保持简单易用的测试.然后在其他地方你可以将accout uid值传递给这个方法等等…
头文件看起来与此类似：

#import <Foundation/Foundation.h>

@class AFHTTPClient;
@protocol RetrieverDelegate;

@interface Retriever : NSObject

- (id)initWithHTTPClient:(AFHTTPClient *)httpClient;

@property (readonly,strong,nonatomic) AFHTTPClient *httpClient;

@property (weak,nonatomic) id<RetrieverDelegate> delegate;

- (void) retrieveEventWithUserId:(NSString *)userId eventId:(NSString *)eventId;

@end


@protocol RetrieverDelegate <NSObject>

- (void) retriever:(Retriever *)retriever didFindEvenData:(NSDictionary *)eventData;

@end

@H_403_4@执行文件：

#import "Retriever.h"
#import <AFNetworking/AFNetworking.h>

@implementation Retriever

- (id)initWithHTTPClient:(AFHTTPClient *)httpClient
{
    NSParameterAssert(httpClient != nil);

    self = [super init];
    if (self)
    {
        _httpClient = httpClient;
    }
    return self;
}

- (void)retrieveEventWithUserId:(NSString *)userId eventId:(NSString *)eventId
{
    NSString *path = [NSString stringWithFormat:@"/user/%@/event/%@",userId,eventId];

    [_httpClient getPath:path
              parameters:nil
                 success:^(AFHTTPRequestOperation *operation,id responSEObject)
    {
        NSDictionary *eventData = [NSJSONSerialization JSONObjectWithData:responSEObject options:0 error:NULL];
        if (eventData != nil)
        {
            [self.delegate retriever:self didFindEventData:eventData];
        }
    }
                 failure:nil];
}

@end

@H_403_4@和测试：

#import <XCTest/XCTest.h>
#import "Retriever.h"

// Collaborators
#import <AFNetworking/AFNetworking.h>

// Test support
#import <OCMock/OCMock.h>

@interface RetrieverTests : XCTestCase

@end

@implementation RetrieverTests

- (void)setUp
{
    [super setUp];
    // Put setup code here; it will be run once,before the first test case.
}

- (void)tearDown
{
    // Put teardown code here; it will be run once,after the last test case.
    [super tearDown];
}

- (void) test__retrieveEventWithUserIdEventId__when_the_request_and_the_JSON_parsing_succeed__it_calls_didFindEventData
{
    // Creating the mocks and the retriever can be placed in the setUp method.
    id mockHTTPClient = [OCMockObject mockForClass:[AFHTTPClient class]];

    Retriever *retriever = [[Retriever alloc] initWithHTTPClient:mockHTTPClient];

    id mockDelegate = [OCMockObject mockForProtocol:@protocol(RetrieverDelegate)];
    retriever.delegate = mockDelegate;

    [[mockHTTPClient expect] getPath:@"/user/testUserId/event/testEventId"
                          parameters:nil
                             success:[OCMArg checkWithBlock:^BOOL(void (^successBlock)(AFHTTPRequestOperation *,id))
    {
        // Here we capture the success block and execute it with a stubbed response.
        NSString *jsonString = @"{\"some valid JSON\": \"some value\"}";
        NSData *responSEObject = [jsonString dataUsingEncoding:NSUTF8StringEncoding];

        [[mockDelegate expect] retriever:retriever didFindEventData:@{@"some valid JSON": @"some value"}];

        successBlock(nil,responSEObject);

        [mockDelegate verify];

        return YES;
    }]
                             failure:OCMOCK_ANY];

    // Method to test
    [retriever retrieveEventWithUserId:@"testUserId" eventId:@"testEventId"];

    [mockHTTPClient verify];
}

@end

@H_403_4@最后要注意的是,AFNetworking 2.0版本被发布,所以考虑使用它,如果它涵盖了您的要求.
