How to use Protractor with Angular 2?
提问by JohnnyC
I use Protractor with Angular 1.x. I would like to migrate to Angular 2.0 step by step but I don't see Protractor in the docs.
我在 Angular 1.x 中使用量角器。我想逐步迁移到 Angular 2.0，但我在文档中没有看到量角器。
Has protractor been dropped since Angular 2? Should I write my tests without using Protractor, using Jasmine instead (or others)?
自 Angular 2 以来量角器是否已被删除？我应该在不使用 Protractor 的情况下编写测试，而是使用 Jasmine（或其他）？

You can test Angular 2 applications with Protractor(starting from Protractor 2.5.0).
您可以使用Protractor（从 Protractor 2.5.0 开始）测试 Angular 2 应用程序。
For Protractor 5.0.0+, you don't have to do anything specific, Protractor will auto-detect the Angular version used in the application under test.
对于Protractor 5.0.0+，您无需执行任何特定操作，Protractor 将自动检测被测应用程序中使用的 Angular 版本。
For Protractor >= 2.5.0 and <= 4.0.14, you would only need to add useAllAngular2AppRoots: trueto your config. Here is a sample.
对于 Protractor >= 2.5.0 和 <= 4.0.14，您只需要添加useAllAngular2AppRoots: true到您的配置中。这是一个示例。
Note that several built-in Protractor matchers would not yet work with Angular2, see:
请注意，几个内置的量角器匹配器还不能与 Angular2 一起使用，请参阅：
There is also that Protractor+Angular2 problem in Firefox (still unresolved), see:
