我最近将我的应用程序升级到 Angular 7。我正在尝试使用特定环境运行我的 ng e2e 测试。此外，我不希望每次为应用程序运行 e2e 测试时都运行新服务器。
使用 Angular 5 时，我曾经使用 CLI 以下列方式执行此操作：
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，在 protractor.conf.test.js 文件中设置了量角器配置（baseURL 和无头浏览器）。每次运行 e2e 测试时，我都使用 no-serve 标志停止运行新服务器。
对于 Angular 7，我在 angular.json 文件中进行了以下更改：

"@schematics/angular:component": {

}

}
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：相当于 --no-serve 标志。
然后我使用 CLI 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？我知道可以设置它的一种方法是通过 devServerTarget 属性。例如：
"devServerTarget": "sample-app:serve:test"
但这也意味着 --no-serve 标志将不被尊重。
有什么方法可以实现这两种结果（特定环境+不发球）？感谢帮助。
