升级到 Angular 6 和 Karma 1.7.1 后，该命令ng test --environment=test不再考虑--environment标志，并且始终使用 dev 的值（来自environment.ts）运行。

有谁知道如何解决这个问题？也不再尊重singleRun: falsefrom并且浏览器在完成后立即关闭。karma.conf.js

不幸的是，我认为 angular Cli 存在问题，因为创建一个新的应用程序并运行ng test --prod它是ng test --configuration=production失败的简写，我相信它必须开箱即用。

fileReplacements我已经通过在配置中使用以下内容解决了这个问题，angular.json尽管我认为这是一种解决方法而不是正确的解决方案：

 "test": {
            ...
            "fileReplacements": [
              {
                "replace": "src/environments/environment.ts",
                "with": "src/environments/environment.test.ts"
              }
            ],
          }

希望它可以帮助其他有同样问题的人。
