Xcode 4 中的 SenTestingKit：异步测试？

发布于 2024-11-10 09:59:31 字数 308 浏览 4 评论 0原文

我一直在寻找一种使用 SenTestingKit 在我的客户端代码和我们的服务器之间进行一些集成测试的方法。我没有任何运气。似乎一旦代码在方法中运行，该对象就会被销毁。这意味着任何异步响应都不会调用选择器。

问题：

有没有办法让对象保持实例化，直到我认为适合销毁它为止 - 即。测试完成后？
如果没有，我如何创建一个在测试完成之前阻塞（即同步操作）的类？

仅供参考，我正在运行一个测试服务器，我知道预期的结果。

我已经做了相当多的谷歌搜索，但还没有看到这样或那样的证据。我相信其他人也会感兴趣。

这个项目 https://github.com/hfossli/AGAsyncTestHelper 有一个非常方便的宏

WAIT_WHILE(<expression_to_evaluate>, <max_duration>);

，可以让你编写像这样的测试

- (void)testDoSomething {

    __block BOOL somethingIsDone = NO;

    [MyObject doSomethingAsyncThenRunCompletionBlockOnMainQueue:^{
        somethingIsDone = YES;
    }];

    WAIT_WHILE(!somethingIsDone, 1.0); 
    NSLog(@"This won't be reached until async job is done");
}

This project https://github.com/hfossli/AGAsyncTestHelper has a very convenient macro

WAIT_WHILE(<expression_to_evaluate>, <max_duration>);

Which ables you to write the test like so

- (void)testDoSomething {

    __block BOOL somethingIsDone = NO;

    [MyObject doSomethingAsyncThenRunCompletionBlockOnMainQueue:^{
        somethingIsDone = YES;
    }];

    WAIT_WHILE(!somethingIsDone, 1.0); 
    NSLog(@"This won't be reached until async job is done");
}

您可以使用信号量来等待异步方法完成。

- (void)testBlockMethod {
    dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);

    // Your block method eg. AFNetworking
    NSURL *url = [NSURL URLWithString:@"http://httpbin.org/ip"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
        NSLog(@"IP Address: %@", [JSON valueForKeyPath:@"origin"]);
        STAssertNotNil(JSON, @"JSON not loaded");
        // Signal that block has completed
        dispatch_semaphore_signal(semaphore);
    } failure:nil];
    [operation start];

    // Run loop
    while (dispatch_semaphore_wait(semaphore, DISPATCH_TIME_NOW))
        [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode
                                 beforeDate:[NSDate dateWithTimeIntervalSinceNow:10]];
    dispatch_release(semaphore);

You can use a semaphore to wait until the asynchronous method finishes.

- (void)testBlockMethod {
    dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);

    // Your block method eg. AFNetworking
    NSURL *url = [NSURL URLWithString:@"http://httpbin.org/ip"];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
        NSLog(@"IP Address: %@", [JSON valueForKeyPath:@"origin"]);
        STAssertNotNil(JSON, @"JSON not loaded");
        // Signal that block has completed
        dispatch_semaphore_signal(semaphore);
    } failure:nil];
    [operation start];

    // Run loop
    while (dispatch_semaphore_wait(semaphore, DISPATCH_TIME_NOW))
        [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode
                                 beforeDate:[NSDate dateWithTimeIntervalSinceNow:10]];
    dispatch_release(semaphore);

}
