Appium

移动自动化工具

自动化测试框架

　　打开调试功能

　　通过安卓手机微信打开debugx5.qq.com，或者直接扫下面二维码（微信版本6.1以上）

　　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
