异步单元测试不被SenTestCase称为 [英] Asynchronous unit test not being called by SenTestCase

问题描述

当我运行我的单元测试，我没有达到我的断点，我认为测试运行不正常我的code。

我试图做一个异步测试，这是我的困难的一部分。

我如何设置的测试，以便 testLookupBook 将被调用，因为我希望，这将导致一切被正确地调用。

我猜测的功能测试应该是在头文件中的某个地方，但我没有开始我的测试方法与测试。

下面是我的头文件：

  @interface jabBookScanTest：SenTestCase {
    jabBookScan *实例;
    NSArray的* SearchResult中;
}
@结束
 

和用于测试的实施是在这里：

   - （无效）MethodNameToCallBack：（jabBookScan *）经理
            resultFromServer：（NSArray的*）■{
    SearchResult中= S;
} - （BOOL）waitForCompletion：（NSTimeInterval）的TimeoutSecs {
    *的NSDate = timeoutDate [NSDate的dateWithTimeIntervalSinceNow：的TimeoutSecs];
    BOOL做= FALSE;
    做{
        [NSRunLoop currentRunLoop] runMode：NSDefaultRunLoopMode beforeDate：timeoutDate];
        如果（[timeoutDate timeIntervalSinceNow]所述; 0.0）
            打破;
    }而（！做）;    返回完成的;
} - （无效）{testLookupBook
   *的NSDate = fiveSecondsFromNow [NSDate的dateWithTimeIntervalSinceNow：5.0];
   [实例lookupBook：（* NSString的）@9780262140874];
   [NSRunLoop currentRunLoop] runUntilDate：fiveSecondsFromNow];
   STAssertTrue（[个体经营waitForCompletion：90.0] @未能得到任何结果的时间）;
}
 

解决方案

我会做这样的

   - （无效）{testLookupBook
   *的NSDate = fiveSecondsFromNow [NSDate的dateWithTimeIntervalSinceNow：5.0];
   [实例lookupBook：（* NSString的）@9780262140874];
   WAIT_WHILE（SearchResult中==为零，1.0）;
}
 

的 WAIT_WHILE（如pressionIsTrue，秒） -macro直到前pression是不正确的或达到时间限制将评估意见。它的下面是使用NSRunLoop图案。你可以在这里找到项目：

When I am running my unit test, I don't reach my breakpoint, and I think that the test isn't properly running my code.

I am trying to do an asynchronous test, which is part of my difficulty.

How do I set up the test so that testLookupBook will be called, as I hope that that will lead to everything else being called properly.

I am guessing that the function to test should be somewhere in the header file, but I did start my test method with test.

Here is my header file:

@interface jabBookScanTest : SenTestCase {
    jabBookScan *instance;
    NSArray *searchResult;
}
@end

And the implementation for the test is here:

- (void)MethodNameToCallBack:(jabBookScan *)manager 
            resultFromServer:(NSArray *)s {
    searchResult = s;
}

- (BOOL)waitForCompletion:(NSTimeInterval)timeoutSecs {
    NSDate *timeoutDate = [NSDate dateWithTimeIntervalSinceNow:timeoutSecs];
    BOOL done = false;
    do {
        [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:timeoutDate];
        if([timeoutDate timeIntervalSinceNow] < 0.0)
            break;
    } while (!done);

    return done;
}

- (void)testLookupBook {
   NSDate *fiveSecondsFromNow = [NSDate dateWithTimeIntervalSinceNow:5.0];
   [instance lookupBook:(NSString *)@"9780262140874"];
   [[NSRunLoop currentRunLoop] runUntilDate:fiveSecondsFromNow];
   STAssertTrue([self waitForCompletion:90.0], @"Failed to get any results in time");
}

解决方案

I would do like this

- (void)testLookupBook {
   NSDate *fiveSecondsFromNow = [NSDate dateWithTimeIntervalSinceNow:5.0];
   [instance lookupBook:(NSString *)@"9780262140874"];
   WAIT_WHILE(searchResult == nil, 1.0); 
}

The WAIT_WHILE(expressionIsTrue, seconds)-macro will evaluate the input until the expression is not true or the time limit is reached. Underneath it is using the NSRunLoop-pattern. You can find the project here:
