Appium [python+appium] 微信小程序测试，无法获取正确的 context

西湖醋鱼 · 2017年04月28日 · 最后由 Senemail 回复于 2018年11月08日 · 2275 次阅读

环境：

nexus5，android6.0.1，微信 6.5.7，appium 版本 1.6.3，python 版本 3.5.2

看过之前思寒大神发的测试帖子，自己也想试试，遇到了几个问题，如下：

  1. 打开美团外卖小程序的首页后，通过 driver.contexts 获取不到 webview 的 context，打印出来只有 native_app，通过微信公众号打开某个链接也同样如此

  2. 按照思寒原帖中的 getContexthandles()，在 python 中直接报错，提示 webdriver 没有此方法

社区了找了不少帖子，大多数都是用 java 实现，问过写 java 的开发同事，getContexthandles() 在 java 中是有此方法，目前困惑的主要问题是，为什么连 webview 的 context 都获取不到，求指点

楼主解决了吗？

刘遥 #5 · 2018年05月09日
对 Cvbnx 回复

driver.switch_to.context('WEBVIEW_com.tencent.mm:appbrand0')

楼主，这个是怎么解决的..目前我们也遇到这个难题。

alex.zhao #2 · 2018年05月11日

是否需要开发的协助，加入如下代码实现
this.appView.setWebContentsDebuggingEnabled(true);

Senemail #8 · 2018年11月08日

请问楼主怎么解决的啊，我问开发，我们应用上面有一个 banner 轮播，banner 点进去是一个 h5 页面，但是这几个 banner 共用一个 webview，导致点进 h5 页面，定位不到页面里面的元素
