如何测试一个方法需要花费超过X秒的时间(使用JUnit)? [英] How to test that a method should take more than X seconds to finish(with JUnit)?

问题描述

基本上，我需要@Test(timeout=X)注释的相反行为.

Basically I need the opposite behaviour of the @Test(timeout=X) annotation.

我要解决的问题是以某种方式检测该方法永远不会结束(作为正确的行为).我假设如果该方法在X秒钟后仍未停止，那么我肯定它将永远不会结束".

The problem I want to solve is to detect in some way that the method never ends (as a right behaviour). I am assuming that if the method didn't stop after X seconds, I am sure "it will never end".

谢谢！

推荐答案

您可以尝试以下方法:

@Test
public void methodDoesNotReturnFor5Seconds() throws Exception {
  Thread t = new Thread(new Runnable() {
    public void run() {
      methodUnderTest();
    }
  });
  t.start();
  t.join(5000);
  assertTrue(t.isAlive());
  // possibly do something to shut down methodUnderTest
}
