为什么可以't Protractor在自动初始化的Angular网站上查找Angular

Why can't Protractor find Angular on an automatically initialized Angular site?

如果不收到以下错误，我就无法使用browser.get()：

Error: Angular could not be found on the page http://localhost:5000/#/login
debug=timing&saveLogs=true&displayAll=true : angular never provided resumeBootstrap

我可以使用browser.driver.get()，但在特定的等待和不稳定的测试中，我会遇到需要编写的问题。

我一直在读这篇文章，没有发现任何有帮助的建议。以下是一些添加的详细信息：

  • 登录页面是Angular应用程序的一部分
  • ng-app在<html>中调用（Protractor默认为<body>，我曾尝试将rootElement设置为html，但没有任何区别）
  • 应用程序中使用了$timeout，但用$interval切换每个$timeout没有任何作用
  • directConnect: true带有chromeDriver，但我认为这不会引起问题
  • 使用Angular 1.2.28和Protractor 2.0

这是完整的错误信息：

问题是Protractor期望默认的window.name:

window.name = "NG_DEFER_BOOTSTRAP!"

但是我正在测试的应用程序没有使用这个默认值。因此，每次都会出现"量角器testForAngular"故障。量角器代码链接：https://github.com/angular/protractor/blob/8a3412e98614bb69978869b34b5b7243619f015d/lib/clientsidescripts.js#L550-L583

在app.js中注释掉自定义window.name =解决了这个问题，但现在我们需要弄清楚如何让Protractor使用不同的变量，或者只为测试动态注释掉这一行。
