ng e2e on TeamCity 只有 @angular/cli 脚本不起作用

Question

我正在使用 TeamCity 10 并尝试获取 @angular/cli 项目以在构建步骤中执行以下操作： 在e2e 脚本之前，一切都运行良好。它会停止构建，我必须强制关闭它。

所以我远程登录了我的构建代理并尝试在它刚刚提取的代码的位置自己运行命令ng e2e，然后我得到一个 chrome 浏览器窗口，但在 10 秒内它崩溃并显示以下内容错误：

PS C:\TeamCity\BuildAgent\work\4038db2ebec7f79b> npm run e2e

> tdportal@0.0.0 e2e C:\TeamCity\BuildAgent\work\4038db2ebec7f79b
> ng e2e

如果一切正常，为什么我不能在这台机器上运行我的 e2e 测试？我需要做些什么不同的事情？

Answer 1

E2E 测试需要在 TeamCity 代理上启动 Chrome 才能运行测试，并且由于代理在未与桌面交互的情况下运行，因此您无法使用 Chrome 运行 E2E 测试。相反，您需要配置 Karma 以使用 PhantomJs 运行 E2E 测试。 Phantom 是一个无头浏览器，无需与桌面交互即可工作。如果您需要示例，请告诉我，我必须挖掘出我的示例。
