xcode 5 xctest测试异步登录网络服务

Question

我已经使用XCode 5做了一个iOS应用程序，现在我想为它做单元测试，我已经为登录服务编写了测试用例，但事情是请求正在形成但没有回应，当我们正常运行应用程序时，我们正在收到适当的响应，我已经用OCUnit测试了相同的服务，并且没有遇到任何问题。在使用XCTest测试Web服务时，我们必须注意哪些具体的事情

Answer 1

随着https://github.com/hfossli/AGAsyncTestHelper你可以写

- (void)testAsyncBlockCallback 
{ 
    __block BOOL jobDone = NO; 

    [Manager doSomeOperationOnDone:^(id data) { 
     jobDone = YES; 
    }]; 

    WAIT_WHILE(!jobDone, 2.0); 
} 

Answer 2

hfossli宏观经济是好的，但输入不添加到runloo p故亦return immediately（挑起CPU的麻烦，据我了解，代码），这里的代码来解决这个问题：

NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; 
[runLoop addPort:[NSMachPort port] forMode:NSDefaultRunLoopMode]; 

wile(waitingForBlock){ 

    [runLoop runMode:NSDefaultRunLoopMode beforeDate:[NSDate dateWithTimeIntervalSinceNow:0.1f]]; 
} 

朴素简单完整的示例使用与假想AFNetworking电话：

- (void)testSync{ 

    __block BOOL waitingForBlock = YES; 

    [self.manager POST:k_WSERVICE_SYNC_ENDPOINT 
      parameters:nil 
       success:^(AFHTTPRequestOperation *operation, id responseObject) { 

       XCTAssertTrue(responseObject != nil, @"Sync: Got empty response, should have received something"); 
       waitingForBlock = NO; 

      } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 

       XCTFail(@"Sync: Failed to connet with error %@",error); 
       waitingForBlock = NO; 
      }]; 


    NSRunLoop *runLoop = [NSRunLoop currentRunLoop]; 
    [runLoop addPort:[NSMachPort port] forMode:NSDefaultRunLoopMode]; 

    while(waitingForBlock){ 

     [runLoop runMode:NSDefaultRunLoopMode beforeDate:[NSDate dateWithTimeIntervalSinceNow:0.1f]]; 
    } 
}
