Appium 测试微信小程序 Webview

Posted 2021-01-10 peachlf

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。
