Question

我最近将应用程序升级到了angular7。我正在尝试使用特定环境运行ng e2e测试。另外，我不希望每次为应用程序运行e2e测试时都运行新的服务器。

使用angular 5时，我曾经使用CLI通过以下方式进行操作：

ng e2e -e test --config protractor.conf.test.js --no-serve

在environment.test.ts文件中设置了我的测试环境，并在protractor.conf.test.js文件中设置了量角器配置（baseURL和无头浏览器）。每当e2e测试运行时，我都使用no-serve标志来停止运行新服务器。

对于angular 7，我在angular.json文件中进行了以下更改：

      "styleext": "css"
    },
    "@schematics/angular:directive": {
      "prefix": "app"
    }
  }
}

我在构建配置下设置了“测试”配置，在服务配置下设置了browserTarget。

来到sample-app-e2e JSON：

protractorConfig：指向相关的量角器配置文件（protractor.conf.test.js）。

空devServerTarget：等效于--no-serve标志。

然后，我使用CLI以以下方式运行e2e测试：

ng e2e --configuration=test

现在，如何设置用于e2e测试的特定环境？我知道可以通过devServerTarget属性设置它的一种方法。例如：

"devServerTarget": "sample-app:serve:test"

但这也意味着--no-serve标志将不被接受。

有什么方法可以同时实现这两种结果（特定环境+无服务）？感谢帮助。

简单地说，您必须完全忽略角度cli 。我疯了，什么也没做，就我而言，我有一个非常大的项目。我每次必须等待几分钟。

使用 ng serve 运行一个Shell，并使用 protractor e2e / your-conf.js

运行另一个Shell

在不提供应用的情况下为angular 7中的ng e2e测试设置特定的环境
