通过微信打开debugx5.qq.com，或者直接扫下面二维码

 

勾选【打开TBS内核Inspector调试功能】

 

Chrome查看页面元素

手机连接电脑，查看是否连接成功。如下展示设备号则为连接成功

 

进入任意小程序，以【X东】为例，在Chrome浏览器访问chrome://inspect/#devices

 

点击inspact，即可查看页面元素

 

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。
