Repro steps

• Step 1: create a new app with ng new its-a-test-app
• Step 2 run e2e tests normally with ng e2e
• Step 3 run e2e tests against production configuration ng e2e --prod

Observed behavior

Configuration 'production' could not be found in project 'its-a-test-e2e'.

Desired behavior

ng e2e --prod --aot should run the e2e tests against the production, AOT-compiled build of the application. I had an issue solely on production/AOT, so I would like to test against this configuration.

[filipesilva]

You can add a configuration for e2e that runs against the production dev server:

"project-name-e2e": {
  "root": "e2e/",
  "projectType": "application",
  "architect": {
    "e2e": {
      "builder": "@angular-devkit/build-angular:protractor",
      "options": {
        "protractorConfig": "e2e/protractor.conf.js",
        "devServerTarget": "project-name:serve"
      },
      "configurations": {
        "production": {
          "devServerTarget": "project-name:build:production"
        }
      }
    },

This question has come up a couple of times so far though. I'll add it to the default schematics.

thanks @filipesilva ! just a note, i had to change "devServerTarget": "project-name:build:production" to "devServerTarget": "project-name:serve:production" (build -> serve).
