小程序的进程微信有很多的进程，每一个小程序都运行在不同的进程中。
进入【X东】后，看下当前运行在哪个进程中

我们可以看到，当前的小程序运行在com.tencent.mm:appbrand0中，记住这个进程，记住啦

Appium编写测试用例最关键的一点，需要添加androidProcess这一项，也就是我们上面的com.tencent.mm:appbrand0
我用python写一个简单的demo

desired_caps = { \'platformName\': \'Android\', \'fastReset\': \'false\', \'deviceName\': \'XXXXXX\', \'appPackage\': \'com.tencent.mm\', \'appActivity\': \'.ui.LauncherUI\', \'fullReset\': \'false\', \'unicodeKeyboard\': \'True\', \'resetKeyboard\': \'True\', \'chromeOptions\': { \'androidProcess\': \'com.tencent.mm:appbrand0\' } } driver = webdriver.Remote(\'http://localhost:4723/wd/hub\', desired_caps) driver.find_element_by_name("发现").click() driver.find_element_by_name("小程序").click() driver.find_element_by_name("X东购物").click() driver.switch_to.context(\'WEBVIEW_com.tencent.mm:appbrand0\') time.sleep(5) print(driver.page_source)

切换Webview失败我遇到过一种切换Webview失败的情况，下面贴上appium的报错日志。

注意最后那一段的chrome和chromedriver的版本

查看对应表可知，两者版本不对应，需要替换chromedriver

将Appium的chromedriver替换为相应版本后，即可成功切换。
