Objective c Kiwi异步测试引发EXC\u错误访问

我做了猕猴桃测试。每4次运行一次，就会引发EXC_BAD_访问异常。这可能是什么原因

它在第一个异步测试的中间停止，调用代码>期望值> /代码>调用。会出什么问题？ 这就是测试：

SPEC_BEGIN(NetworkTest)

describe(@"The call to the external service", ^{

context(@"context", ^{

    __block id origin = nil;
    __block int x = 0;
    __block AFJSONRequestOperation *operation;

    beforeEach(^{
        /*
         [OHHTTPStubs addRequestHandler:^OHHTTPStubsResponse*(NSURLRequest *request, BOOL onlyCheck){
         return [OHHTTPStubsResponse responseWithFile:@"test.json" contentType:@"text/json" responseTime:1.0];
         }];
         */

        origin = nil;

        NSURLRequest* request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://httpbin.org/ip"]];

            operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
            origin = [JSON valueForKeyPath:@"origin"];
            x = 1;
        } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
            // no action
                origin = @"no";
            }];

        [operation start];

        });

        afterEach(^{
            origin = @"";
            operation = nil;
        });



        it(@"should be not nil", ^{

            [[expectFutureValue(origin) shouldEventuallyBeforeTimingOutAfter(3.0)] shouldNotBeNil];

        });


        it(@"should set x to 1", ^{
            [[expectFutureValue(theValue(x)) shouldEventuallyBeforeTimingOutAfter(3.0)] equal:theValue(1)];
        });


        it(@"should return an IP address", ^{

            [[expectFutureValue(origin) shouldEventuallyBeforeTimingOutAfter(3.0)] equal:@"10.1.48.223, 194.50.118.230" ];
        });




    });

});

我还修改了用于零检查的

评估
方法：

- (BOOL)evaluate 
{
    if (self.subject == nil) {
        NSLog(@"The subject is NIL");
    }
    /** handle this as a special case; KWValue supports NSNumber equality but not vice-versa **/
if ([self.subject isKindOfClass:[NSNumber class]] && [self.otherSubject isKindOfClass:[KWValue class]]) {
        return [self.otherSubject isEqual:self.subject];
    }
    return [self.subject isEqual:self.otherSubject];
}

这是未发生故障时的结果日志：
（测试本身失败，但程序运行良好）


测试用例“-[networktestthecalltotheexternalservice\u Context\u shouldlreturnanipaddress]”已启动。
[参考译文]受试者为零

/Users/../KiwiTests/BMNetworkManagerTests.m:81:错误：-[NetworkTest调用外部服务\u Context\u shouldneturnanipaddress]：“调用外部服务，Context，应该返回一个IP地址”[失败]，预期等于“10.1.48.23194.50.118.230”，获得“10.1.48.252194.50.118.230”

你有堆叠痕迹，还是猕猴桃把它弄脏了？是的，我有。给你，我不能用你的代码复制这个。您是否能够在
KWEqualMatcher
的
evaluate
方法中设置断点，以便更好地了解故障的确切位置？另外，你是否尝试过干净的构建、更新猕猴桃椰子荚等？我已经为这个问题添加了更多细节。希望能有帮助。
