如何通过Junit和timeout获得成功? [英] How to get a success with Junit and timeout?

问题描述

@Test (expected=TimeoutException.class,timeout=1000)
public void fineForFiveSeconds() {
    foo.doforever();
    fail("This line should never reached");
}

这是我的测试代码. 我只想运行doforever()一段时间，然后使测试成功.

This is my test code. All I want is to run doforever() for some time period then make the test succeed.

推荐答案

尝试一下:

在线程中执行逻辑，休眠并检查线程是否仍在运行.

Execute the logic in a thread, sleep and check if the thread is still alive.

@Test
public void fineForFiveSeconds() throws InterruptedException {
  Thread thread = new Thread() {
    @Override
    public void run() {
      foo.doforever();
    }
  };

  thread.start();

  //Let the current thread sleep (not the created thread!)
  Thread.sleep(5000);

  assertTrue(thread.isAlive());
}
