selenium - 无法将 Firefox v52.0 与 Protractor 一起使用

Question

我目前在使用 GeckoDriver 时尝试在我的 Angular2 站点上运行 Protractor 测试时遇到问题。

我正在使用 Selenium Standalone Server 来运行我的测试，它们可以在 Chrome 和 IE11 中运行，但是当我尝试使用 Firefox 运行时，出现以下错误:

如果我尝试使用 directConnet 运行 Firefox 测试，我会收到另一个错误:

不知道从这里去哪里!

版本

角度:2.4.6

Protractor :5.1.1

Selenium 独立服务器:3.3.1

壁虎驱动程序:0.15.0

火狐浏览器:52.0

Answer 1

Permission denied to access property "invoke"是 known issue在 Zone.js 中，特定于 Zone.js 和使用 WebDriver 运行的 Firefox。它在 0.8.7 版本中得到修复。问题涉及 Zone.js 如何修补浏览器，唯一的解决方法是升级。
Unable to parse new session response也是known issue使用 Firefox 52 和 directConnect: true .不幸的是，唯一的解决方案是使用 Selenium Standalone。
