public voidtest_parkFor_1()
Test the case where the park times out.

        Thread parkerThread = new Thread(parker);
        Thread waiterThread =
            new Thread(new WaitAndUnpark(1000, parkerThread));

        parkerThread.start();
        waiterThread.start();
        parker.assertDurationIsInRange(500);
public voidtest_parkFor_2()
Test the case where the unpark happens before the timeout.

        Parker parker = new Parker(false, 1000);
        Thread parkerThread = new Thread(parker);
        Thread waiterThread =
            new Thread(new WaitAndUnpark(300, parkerThread));

        parkerThread.start();
        waiterThread.start();
        parker.assertDurationIsInRange(300);
public voidtest_parkFor_3()
Test the case where the thread is preemptively unparked.

        Parker parker = new Parker(false, 1000);
        Thread parkerThread = new Thread(parker);

        UNSAFE.unpark(parkerThread);
        parkerThread.start();
        parker.assertDurationIsInRange(0);
public voidtest_parkUntil_1()
Test the case where the park times out.

        Parker parker = new Parker(true, 500);
        Thread parkerThread = new Thread(parker);
        Thread waiterThread =
            new Thread(new WaitAndUnpark(1000, parkerThread));

        parkerThread.start();
        waiterThread.start();

            new Thread(new WaitAndUnpark(300, parkerThread));

        parkerThread.start();
        waiterThread.start();
        parker.assertDurationIsInRange(300);
public voidtest_parkUntil_3()
Test the case where the thread is preemptively unparked.
