NUnit可以期待超时吗? [英] Can NUnit expect a timeout?

问题描述

我想测试一种在特定情况下希望阻止的方法.

I would like to test a method that I am expecting to block in a specific situation.

我尝试了TimeoutAttribute和ExpectedExceptionAttribute的组合:

[Test]
[Timeout(50), ExpectedException(typeof(ThreadAbortException))]
public void BlockingCallShouldBlock()
{
    this.SomeBlockingCall();
}

不幸的是，这不起作用，因为我在此处读到的ThreadAbortException似乎被NUnit本身抓住了.

Unfortunately this does not work as the ThreadAbortException I was reading about here seems to get caught by NUnit itself.

是否有一种方法可以预期超时(使用NUnit)?

Is there a way to expect timeouts (with NUnit)?

推荐答案

对于这样的问题，我可能会使用 Task.Wait(int) 或

For a problem like this, I would probably use Task and Task.Wait(int) or Task.Wait(TimeSpan). For example:

[Test]
public void BlockingCallShouldBlock()
{
    var task = Task.Run(() => SomeBlockingCall());
    var completedInTime = task.Wait(50); // Also an overload available for TimeSpan
    Expect(completedInTime, Is.False);
}

但是请注意，这将在后台线程上调用SomeBlockingCall，但是对于大多数单元测试而言，这不是问题.

Be warned however, this will invoke SomeBlockingCall on a background thread, but for the majority of unit tests, this is a non-issue.
