如何让 Android TestRunner 等到活动完成

Question

我在测试用例结束时关闭一个活动，因此它在下一个测试用例的开头为 null：

public void test1() throws Exception {
    //activity is calling the RegisterActivity in onCreate
    activity = getActivity();
    // register next activity that need to be monitored.
    RegisterActivity nextActivity = (RegisterActivity) getInstrumentation()
        .waitForMonitorWithTimeout(activityMonitor, 5);
    // next activity is opened and captured.
    assertNotNull(nextActivity);
    if (nextActivity != null) {
        nextActivity.finish();
    }
}
public void test2() throws Exception {
    //nextActivity.finish() from the previous test has not yet finished
    //body of test2
    //...
    //...
}

如果我在test1中设置线程睡眠，那么问题就解决了：

    if (nextActivity != null) {
        nextActivity.finish();
        Thread.sleep(1500);
    }

有没有更好的方法？有没有一种方法可以阻止测试运行程序，直到下一个活动完成？

尝试为下一个要运行的 Activity 创建一个new thread。调用 thread.start() 方法后，调用要阻止 TestRunner 的thread.join()。
