1. 主要功能
使用此方法可以处理中断问题,从而保证测试用例的正常运行。
2. 相关API
| API | 说明 |
| registerWatcher (String name, UiWatcher watcher) | 注册一个监听器，当无法匹配到对象的时候，触发监听器 |
| removeWatcher (String name) | 取消之前注册的指定的监听器 |
| resetWatcherTriggers () | 重置已出发过的UiWatcher |
| runWatchers () | 运行所有的监听器 |
3.简单示例
3.1 用例代码
@Test
public void testCase09() throws InterruptedException { final UiObject2 ui = mDevice.findObject(By.text("短信"));
//注册监听器
mDevice.registerWatcher("testWatcher", new UiWatcher() {
@Override
public boolean checkForCondition() {
if(mDevice.hasObject(By.text("联系人"))){
ui.click();
Log.i("testWatcher", "监听器被触发了");
return true;
}
Log.i("testWatcher", "监听器未被触发");
return false;
}
}); //运行用例步骤
mDevice.wait(Until.findObject(By.text("写短信")), 2000);
UiObject2 btn = mDevice.findObject(By.text("写短信"));
btn.click();
Thread.sleep(2000);
mDevice.pressBack(); //重置监听器
mDevice.resetWatcherTriggers();
mDevice.wait(Until.findObject(By.text("写短信")), 2000);
btn.click();
Thread.sleep(2000);
mDevice.pressBack();
Log.i("testWatcher", "重置监听器成功"); //移除监听器
mDevice.removeWatcher("testWatcher");
Log.i("testWatcher", "移除监听器成功");
mDevice.wait(Until.findObject(By.text("写短信")), 2000);
btn.click();
Thread.sleep(2000);
mDevice.pressBack(); }
