unit-testing - Firebase 函数 TypeScript 单元测试 devDependencies

Question

遵循此处的指南:https://firebase.google.com/docs/functions/unit-testing
我正在尝试为我的 TS 函数编写单元测试。
这是我的 package.json:

{
  "name": "functions",
  "scripts": {
    "lint": "tslint --project tsconfig.json",
    "build": "tsc",
    "serve": "npm run build && firebase serve --only functions",
    "shell": "npm run build && firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log",
    "test": "mocha --reporter spec"
  },
  "main": "lib/index.js",
  "dependencies": {
    "@types/algoliasearch": "^3.27.0",
    "@types/axios": "^0.14.0",
    "@types/nodemailer": "^4.6.0",
    "@types/stripe": "^5.0.11",
    "algoliasearch": "^3.27.1",
    "axios": "^0.18.0",
    "firebase-admin": "~5.12.0",
    "firebase-functions": "^1.0.3",
    "nodemailer": "^4.6.4",
    "stripe": "^5.8.0",
    "webpack": "^4.7.0"
  },
  "devDependencies": {
    "@types/node": "^9.6.6",
    "firebase-functions-test": "^0.1.2",
    "mocha": "^5.2.0",
    "ts-loader": "^4.2.0",
    "tslint": "^5.8.0",
    "typescript": "^2.8.3",
    "webpack-cli": "^2.1.2",
    "webpack-node-externals": "^1.7.2"
  },
  "private": true
}

我有1个问题和1个问题。

问题:
我无法导入 firebase-functions-test
在我的 index.test.ts 文件中。
它仅在依赖项中而不是在 devDependencies 中寻找它...
(将它添加到依赖项中可以解决它)。

问题:
我可以将所有@types 移动到 devDependencies 吗？

谢谢。

如果我是对的，你可能会得到类似的错误

Module 'firebase-functions-test' is not listed as dependency in package.json

实际上这是因为您启用了 tslint 规则无隐式依赖关系。您可以禁用它，然后在单元测试中导入 devDependencies 时不会出错。
