objective-c - 如何使用 Kiwi 异步测试委托(delegate)

Question

伙计们， 多年来，我一直在努力寻找一些关于如何使用 Kiwi 测试来异步测试委托(delegate)方法的好例子。

我有一个管理器类，它定义了测试协议(protocol)，并在委托(delegate)中返回了通过和失败方法。任何人都可以提供有关如何执行此操作的示例代码吗？我可以让测试类本身实现以调用管理器上的方法吗？

谢谢大家

你可以像例子那样做

 SPEC_BEGIN(IFStackOverflowRequestSpec)

describe(@"IFStackOverflowRequestSpec", ^
{
    context(@"question request", ^
    {
        __block IFViewController *controller = nil;

         beforeEach(^
         {
             controller = [IFViewController mock];
         });

        it(@"should conform StackOverflowRequestDelegate protocol", ^
        {
             [[controller should] conformToProtocol:@protocol(StackOverflowRequestDelegate)];
        });

         it(@"should recieve receivedJSON", ^
         {
             NSString *questionsUrlString = @"http://api.stackoverflow.com/1.1/search?tagged=iphone&pagesize=20";

             IFStackOverflowRequest *request = [[IFStackOverflowRequest alloc] initWithDelegate:controller urlString:questionsUrlString];
             [[request fetchQestions] start];
             [[[controller shouldEventuallyBeforeTimingOutAfter(3)] receive] receivedJSON:any()];
         });

         it(@"should recieve fetchFailedWithError", ^
         {
             NSString *fakeUrl = @"asda";
             IFStackOverflowRequest *request = [[IFStackOverflowRequest alloc] initWithDelegate:controller urlString:fakeUrl];
             [[request fetchQestions] start];
             [[[controller shouldEventuallyBeforeTimingOutAfter(1)] receive] fetchFailedWithError:any()];
         });
    });
});
