Question

能够从Appium 1.0.0.3中的Android chrome浏览器成功运行Youtube页面（WebView）。

伙计们，我被击中了。请帮助我实现目标。

- I can't able to identify elements inside WebView using "uiautomatorviewer.bat"

- I can't able to switch to WebView through following code
       - driver.switch_to.context('WEBVIEW')
          one more I tried
       - driver.switch_to.context(webview)

我的目标：

场景1：

在Android Chrome浏览器上打开Youtube页面。选择任何视频进行播放。点击暂停并播放。点击全屏按钮。

场景2：

在Android Chrome浏览器上打开网址：“http://m.youtube.com/watch?v=7-7knsP2n5w”。点击播放按钮。

示例代码：

from appium import webdriver

desired_caps = {}
desired_caps['automationName'] = 'Appium'
desired_caps['platformName'] = 'Android'
desired_caps['platformVersion'] = '4.4'
desired_caps['deviceName'] = 'Nexus 7'
desired_caps['browserName'] = 'Chrome'

driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)

driver.get('http://m.youtube.com')

driver.switch_to.context('WEBVIEW')    # Unable to switch to webview. Getting following error.

Answer 1

初始化webdriver时，网址应设置为http://0.0.0.0:9515/wd/hub/

您在切换上下文时遇到问题，因为Appium没有成功与该应用程序通信。

尝试print driver.page_source当它工作时（并打印出页面xml），其余部分（切换上下文等）也应该有用。
