Repro steps

ng e2e --no-progress

The log given by the failure

Unknown option: '--progress'

Desired functionality

I'd prefer to be able to turn of progress logging for continuous integration builds.

There is no progress logging in e2e tests per se. The progress reporting comes from the dev server target. With some very limited exceptions, we don't want to add "pass-through" options as that limits what options a given builder can use.

You can add a configuration to your dev server that turns off progress, and then use that one in the e2e target, then call it via ng e2e --configuration=ci.

        "serve": {
          "builder": "@angular-devkit/build-angular:dev-server",
          "options": {
            "browserTarget": "latest-project:build"
          },
          "configurations": {
            "ci": {
              "progress": false
            }
          }
        },
// ...
        "e2e": {
          "builder": "@angular-devkit/build-angular:protractor",
          "options": {
            "protractorConfig": "e2e/protractor.conf.js"
          },
          "configurations": {
            "ci": {
              "devServerTarget": "latest-project:serve:ci"
            }
          }
        },
