在鼓捣 atx 基于 python 的 uiautomator2 的 toast 消息提示。之前看到过基于 appium uiautomator2 的 toast 消息的捕获方案。
所以得先弄懂，弄通，以致 debug 通 appium uiautomator2 的 toast 消息的原理与调用的链路和包关系。
在 ATX363 python3.6.3 虚拟环境中 安装 Appium-Python-Client
(ATX363) cmd@TR:~$ pip install Appium-Python-Client

再安装 selenium 发现已经提示安装好了，应该是 Appium-Python-Client 关联安装的
(ATX363) cmd@TR:~$ pip install selenium
Requirement already satisfied: selenium in ./.pyenv/versions/3.6.3/envs/ATX363/lib/python3.6/site-packages

(ATX363) cmd@TR:~$ pip list
DEPRECATION: The default format will switch to columns in the future. You can use --format=(legacy|columns) (or define a format=(legacy|columns) in your pip.conf under the [list] section) to disable this warning.

USB 连接我的小米 mix2 真机 ，开启手机开发者选项，开始 usb 调试模式和其它相关。
cmd@TR:~$ adb devices -l
List of devices attached

向手机安装百度阅读 apk
cmd@TR:~/app$ adb install baiduyuedu_5150.apk
Success
犯贱又初始化向手机安装了 atx 的 uiautomator2 相关手机端

[Appium] Welcome to Appium v1.7.2
[Appium] Non-default server args:

使用 pycharm，先去 File-> Settings-> Project -> Project Interpreter -> Add Local
在 Existing environment 中选择/home/cmd/.pyenv/versions/ATX363/bin/python 切换到 ATX363 虚拟环境，以便 import 到在该环境安装的 appium python clinet 和 selenium 包。
编辑 FindToastTest.py 脚本，内容如下

运行该脚本 已经安装有 atx-uiautomator2 的手机，连接 的 appium server 会报错
手机端卸载掉 uiautomator2 后，可以正常跑 FindToastTest.py 期间手机端弹出提示安装了 io.appium.uiautomator2.server 和 io.appium.uiautomator2.server.test
（当然如果是第一次用该手机的话还会提示安装 Unlock 和 Appium Setting ）
参考了以下前辈和大神的方案，站在巨人的肩膀上，能让我们走的更远，感谢以下人士的不懈努力和分享。

final WebDriverWait wait = new WebDriverWait(driver,3);

throw new AssertionError("找不到"+toast);

参考这个帖子http://testerhome.com/topics/2354 回帖中的 waitForElement，我自己写了一个 appium selendroid 模式下的 python 函数查找 toast
message：消息内容
timeout：超时时间
poll_frequency：查询步长
driver：就是driver
from
selenium import webdriver

atx-uiautomator2 的 toast 消息也测试通过了
atx-uiautomator2 识别 android toast 测试
