如何让Android TestRunner等待活动结束

Question

我在一个测试用例的结尾处关闭一个Activity，因此在下一个测试用例的开头它为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中设置了线程睡眠，那么问题就解决了：

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

有更好的方法吗？ 有没有一种方法可以阻止TestRunner，直到nextActivity完成？

Answer 1

尝试为要运行的nextActivity创建一个new thread 。调用thread.start()方法后，在要阻止TestRunner的位置调用thread.join() 。
