如何用JMockit模拟出Thread.sleep()?

Noe*_*Yap 6 static-methods jmockit junit4

我有以下代码:

class Sleeper {
    public void sleep(long duration) {
        try {
            Thread.sleep(duration);
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt();
        }
    }
}

如何使用JMockit测试如果Thread.sleep()抛出InterruptedException,则调用Thread.currentThread()。interrupt()吗?

有趣的问题。测试起来有点棘手,因为模拟 的某些方法java.lang.Thread可能会干扰 JRE 或 JMockit 本身,并且因为 JMockit(当前)无法动态模拟本机方法,例如sleep. 也就是说,仍然可以做到:

public void testResetInterruptStatusWhenInterrupted() throws Exception
{
    new Expectations() {
       @Mocked({"sleep", "interrupt"}) final Thread unused = null;

       {
           Thread.sleep(anyLong); result = new InterruptedException();
           onInstance(Thread.currentThread()).interrupt();
       }
    };

    new Sleeper.sleep();
}
