量角器 - 失败：运行 testForAngular 时出错：脚本在超时到期之前未完成

Question

在使用 Protractor 对 Angular 应用程序运行端到端回归测试时，我无法克服这些失败。当我对 Chrome 和 Firefox 运行相同的测试时，两者总是通过。但是，当针对 Safari 或 Safari Technology Preview 运行时……我遇到了同样的堆栈故障。这是一个 Angular 应用程序，所以我不能只是“关闭”或“禁用”等待 Angular。

节点 8.0.0、量角器 5.1.1、npm 5.0.4、Selenium 3.4.0.jar、macOS Sierra 10.12.5

Safari - 10.1.1 (12603.2.4)

Safari 技术预览版 - 第 35 版（Safari 11.0、WebKit 12604.1.29）

*允许启用远程自动化

Safari 堆栈：

NoSuchWindowError: A request to use a window could not be satisfied because the window could not be found.

Failed: Error while running testForAngular: A script did not complete before its timeout expired.

Safari 技术预览栈：

Failed: Error while running testForAngular: A script did not complete before its timeout expired.

Command duration or timeout: 20.01 seconds

据我了解，问题的根源不是 Angular 等待功能。出现是因为有错误NoSuchWindowError: A request to use a window could not be satisfied because the window could not be found.。 看看issue on the SeleniumHQ github
