UiAutomator UiAutomator2 测试 H5 页面,切换 webview 后报没有找到对应的 ChromeDriver 版本

测试手机:
华为/vivo手机,webView版本是78.0的(其他手机不会出现下面的问题,如:小米、Honor)
前置描述
  1. APP 已经开启 Debug 模式(用 appium 操作是没问题的)
  2. 用 Chome 浏览器查看'chrome://inspect/#devices', 版本如下
  3. 已经准备了对应的 ChomeDriver 版本
现象
  1. chromedriver 实例化后,发现会拉起本地 Chrome 浏览器
  2. 接着就报 ChromeDriver 版本不对

#### 相关日志如下:

代码都不发一下?

chromedriver 实例化后,发现会拉起本地 Chrome 浏览器

这段话很奇怪,你测试的是手机里的浏览器打开 web 页面,还是你的 app 内置 webview 里的 web 页面?如果是后者,我理解只需要实例化 appium driver,用 driver 内部切换 context 的方法来切换到 webview 就好(appium 有内置 chromedriver ),不需要实例化 chromedriver 。

最好还是直接贴一下你的脚本代码吧。

这个是 ChromeDriver 类文件,跟您写的应该是一样的

您好,我用的是 uiautomator2 框架, Appium 没问题😁

Forkey 回复

额,你这个回答和我的问题对不上吧。

另外,官方文档里 options 不是你代码里这个写法传进去的,而是下面这样:

from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option('androidPackage', 'com.android.chrome')
driver = webdriver.Chrome('./chromedriver', options=options)
driver.get('https://google.com')
driver.quit()

初始化启动 chromedriver 的时候就传入 options 了。
官方文档地址:https://chromedriver.chromium.org/getting-started/getting-started---android

你确定过你现在这种写法(命令行调起 chromedriver 文件,然后用 webdriver.Remote 连上 chromedriver 服务并传入 capabilities )是可用的吗?

陈恒捷 回复

您好,

  1. 我是测试 APP 里面的 webview 页面
  2. 我用 appium 操作 webview(就如您所说的 context),是没问题的
  3. 现在用上述的代码,我在小米及 Honor 是可以跑成功的,但是华为跟 vivo 就不行
  4. 我是参考这篇文章的,ATX ATX-uiautomator2 app 原生 + webview 的实际操作记录 (安卓) https://testerhome.com/topics/15998
  5. 按照您的意思是在 lunch_driver 时就应该传入配置信息吗?
Forkey 回复

建议你可以试试官方文档给的方法?

PS:部分手机可以,这个信息麻烦下次提问的时候就给出吧。。。
