我的测试用例永无止境

Question

我正在尝试测试对服务器的异步请求。 我发送请求，得到响应，但是测试挂起并且没有结束

这是我的测试：

-(void)testClearAppsCache{
    XCTestExpectation *expectation = [self expectationWithDescription:@"callServicesWithParameters"];
    [self.apiClient callServicesWithParameters:nil//@{@"version":@""}
                                       success:^(BridgeModel *bridge) {
                                           BOOL onMainThread = [NSThread isMainThread];
                                           XCTAssertFalse(onMainThread,@"should be on main thread");
                                           XCTAssertNotNil(bridge);
                                           [expectation fulfill];
                                           NSLog(@"done");
                                       }

                                       failure: ^(NSError * error) {
                                           [expectation fulfill];
                                           LogInfo(@"error gettings services:%@",error);
                                       }];

    [self waitForExpectationsWithTimeout:5.0 handler:^(NSError *error) {
        NSLog(@"waiting for expectation");
        if(error){
            NSLog(@"error:%@",error);
            XCTFail(@"error:%@",error);
        }else {
            XCTAssertNil(error,@"test finished");
        }
    }];

    NSLog(@"done testing");

}

这是测试后打印的日志：

请求运行并成功，收到正确的响应和状态码，成功块运行，但是在成功块完成后，没有任何反应，测试挂起 - 我该如何解决？

Answer 1

您在调用 [expectation fulfill]; 之后正在记录您的块可能会在 log 语句之前返回，看起来挂起，即使它确实完成了。

交换行的顺序，确保你直到最后才完成。
