如何进行JUnit测试等待? [英] How can I make a JUnit test wait?

问题描述

我有一个JUnit测试，我想同步等待一段时间.我的JUnit测试如下:

I have a JUnit test that I want to wait for a period of time synchronously. My JUnit test looks like this:

@Test
public void testExipres(){
    SomeCacheObject sco = new SomeCacheObject();
    sco.putWithExipration("foo", 1000);
    // WAIT FOR 2 SECONDS
    assertNull(sco.getIfNotExipred("foo"));
}

我尝试了 Thread.currentThread().wait()，但是它抛出了 IllegalMonitorStateException (如预期).

I tried Thread.currentThread().wait(), but it throws an IllegalMonitorStateException (as expected).

有什么窍门吗?还是需要其他显示器?

Is there some trick to it or do I need a different monitor?

推荐答案

Thread.sleep(2000); 怎么样?:)
