我正在关注Zusstand wiki 来实施 testing,但提供的解决方案不适用于应用程序渲染的基本测试。我的项目建立在Electron React Boilerplate样板项目之上。

这是完整的错误。Jest 使用 node withexperimental-vm-modules因为我遵循Jest 文档来支持 ESM 模块。

$ cross-env NODE_OPTIONS=--experimental-vm-modules jest
(node:85003) ExperimentalWarning: VM Modules is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
jest-haste-map: Haste module naming collision: myproject
  The following files share their name; please adjust your hasteImpl:
    * <rootDir>/package.json
    * <rootDir>/src/package.json

notifs.ts文件顶部,正常导入 Zusand 时使用import create from 'zustand'.

开玩笑的配置package.json

    ...
    "moduleNameMapper": {
      "\\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "<rootDir>/config/mocks/fileMock.js",
      "\\.(css|less|sass|scss)$": "identity-obj-proxy",
      "zustand": "<rootDir>/src/__mocks__/zustand.js",
    },
    "transformIgnorePatterns": [
      "node_modules/(?!(zustand)/)",
      "<rootDir>/src/node_modules/"
    ],
    "moduleDirectories": [
      "node_modules",
      "src/node_modules"
    ],
    "moduleFileExtensions": [
      "js",
      "jsx",
      "ts",
      "tsx",
      "json"
    ],
    "moduleDirectories": [
      "node_modules",
      "src/node_modules"
    ],
    "extensionsToTreatAsEsm": [
      ".ts",
      ".tsx"
    ],

    ...

我留下的./src/__mocks__/zustand.js文件与 Zusand wiki 测试页面中的文件完全相同。无论我是否zustandtransformIgnorePatterns.

我的 Babel 配置包含[require('@babel/plugin-proposal-class-properties'), { loose: true }],在插件部分中,并且output.library.type'commonjs2'

tsconfig.jsoncompilerOptions.module设置为"CommonJS",项目的package.json "type"字段设置为"commonjs"

依赖版本:

    "@babel/core": "^7.12.9",
    "@babel/preset-env": "^7.12.7",
    "@babel/preset-react": "^7.12.7",
    "@babel/preset-typescript": "^7.12.7",
    "@babel/register": "^7.12.1",

    "jest": "^27.0.6",
    "regenerator-runtime": "^0.13.9",
    "source-map-support": "^0.5.19",
    "typescript": "^4.0.5",
    "webpack": "^5.5.1",
    "zustand": "^3.5.5"

我不知道还有什么相关的,如果需要其他任何东西,请告诉我。任何和所有的帮助表示赞赏,感谢您的时间。

使用 jest 28.0.0-alpha.0 将简单地解决问题。我认为问题在于zustand使用“.mjs”作为入口点。
