如何编写单元测试来测试Thread.Sleep的功能？

import org.junit.Test;

public class ThreadSleepTest {

    @Test
    public void testThreadSleep() throws InterruptedException {
        long startTime = System.currentTimeMillis();
        Thread.sleep(1000); // 休眠1秒钟
        long endTime = System.currentTimeMillis();

        long elapsedTime = endTime - startTime;
        // 使用断言验证休眠时间是否符合预期
        assert elapsedTime >= 1000 && elapsedTime < 1100;
    }
}
