ios - 如何在 IOS 中使用 cedar 测试 http 请求块

Question

我想用一个方法来测试一个名为 BookService 的类来获取书籍信息列表。我应该怎么做才能同时覆盖成功块和失败块？这是我的方法代码：

-(void)getRequestWithURL:(NSString *)urlStr withKey:(NSString *)keyWord completion:(void (^)(NSMutableArray *data))complete{
if(manager==nil)
    manager = [AFHTTPSessionManager manager];
NSLog(@"%@",keyWord);
NSMutableArray *datas = [NSMutableArray new];
NSDictionary *dict=@{
                     @"q":keyWord,
                     @"count":@10
                     };

[manager GET:urlStr parameters:dict progress:^(NSProgress * _Nonnull downloadProgress) {} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject){
    //NSMutableArray *books=[NSMutableArray new];
    NSArray *json= responseObject[@"books"];

    for(id book in json){
        BookInfo *b = [[BookInfo alloc]initWithJson:book];
        NSLog(@"%@",b.author[0]);
        [datas addObject:b];
    }
    complete(datas);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error){
    NSLog(@"返回失败");
    NSLog(@"%@",error);
    complete(nil);
}];

}

这是我的雪松测试代码

SPEC_BEGIN(BookServiceSpec)

    describe(@"BookService", ^{
__block BookService *bookService;
__block AFHTTPSessionManager *manager;
__block UITableView *tableView;
__block NSMutableArray *data;
__block NSString *key;
__block NSString *url;

beforeEach(^{
    tableView = [[UITableView alloc]init];

    data = [[NSMutableArray alloc]init];
});


describe(@"test bookService", ^{

    context(@"get book success", ^{
        beforeEach(^{
            manager = fake_for([AFHTTPSessionManager class]);
            manager stub_method(@selector(GET:parameters:progress:success:failure:));
            bookService = [[BookService alloc]initWithManager:manager];

            url = @"https://api.douban.com/v2/book/search";
            key=@"java";
            //bookService stub_method(@selector(getRequestWithURL:withKey:completion:));

        });
        it(@"should manager not be nil", ^{
            [bookService getRequestWithURL:url withKey:key completion:^(NSMutableArray *data) {
                bookService should have_received("getRequestWithURL:withKey:completion");
            }];
        });  
    });
