android UiAutomator聊天室用例中断言的应用

本人最近在学习UiAutomator的时候，写一个聊天室的用例，刚好练习一下断言的应用。分享出来，供大家参考。

	//班级聊天测试
	public void charroomSendAndSwitchSwitch() throws UiObjectNotFoundException {
		login();
		waitForTextAndClick("聊天");
		waitForTextAndClick("班级群聊");
		String text = "我是测试！"+getNow();
		writeText(text);
		waitForTextAndClick("发送");
		assertTrue(getUiObjectByText(text).exists());
		//验证切换老师按钮
		waitForResourceIdAndClick("com.gaotu100.superclass:id/chatroom_header_filter_msg_image");//点击切换老师按钮
		assertFalse(getUiObjectByText(text).exists());
		waitForResourceIdAndClick("com.gaotu100.superclass:id/chatroom_header_filter_msg_image");//点击切换老师按钮
		assertTrue(getUiObjectByText(text).exists());
		}

中间有一个切换老师的按钮，点击之后就只能看到老师的发言。不能看到自己的发言了。下面是login()方法。

	//登录学生app
	public void login() throws UiObjectNotFoundException {
		waitForResourceIdAndClick("com.gaotu100.superclass:id/view_shared_tabbar_me");//点击我的
		if (!getUiObjectByText("我的班课").exists()) {
			pressTimes(KeyEvent.KEYCODE_FORWARD_DEL, 12);//清除已有帐号
			getUiObjectByResourceId("com.gaotu100.superclass:id/login_username").setText("1320454218");//输入帐号
			getUiObjectByResourceId("com.gaotu100.superclass:id/login_password").setText("qqqqqq");//输入密码
			getUiObjectByResourceId("com.gaotu100.superclass:id/login_button").clickAndWaitForNewWindow();//点击登录
			}
		}
