Angular：从 Karma 移动到 Jest 后，错误 "Unrecognized CLI Parameters"

Question

我将我的项目从 Angular 6.4 更新到 Angular 7.1，现在运行脚本：ng test app-name --coverage 给我错误：

● Unrecognized CLI Parameters:

  Following options were not recognized:
  ["main", "polyfills", "tsConfig"]

  CLI Options Documentation:
  https://jestjs.io/docs/en/cli.html

angular.json 中测试命令的配置如下所示：

"test": {
  "builder": "@angular-builders/jest:run",
  "options": {
    "main": "apps/app-name/src/test.ts",
    "polyfills": "apps/app-name/src/polyfills.ts",
    "tsConfig": "apps/app-name/tsconfig.spec.json",
    "configPath": "./jest.config.json",
    "styles": [
      "apps/app-name/src/styles.scss"
    ],
    "scripts": [],
    "assets": [
      "apps/app-name/src/favicon.ico",
      "apps/app-name/src/assets"
    ]
  }
},

我应该如何更新配置以与 Angular 7 兼容？

Answer 1

错误是我在转移到 Jest 时忘记了 remove/replace 旧的 karma-builder 配置。

显然 Angular 7 检查类似的东西比 Angular 6 更好（万岁！），所以我误认为它是 Angular 或 Jest 错误。
