Do not import @jest/globals outside of the Jest test environment

[biglebronski]

Hi,

I see in the docs that mocks are implemented in the global scope during mount(). I have some tests that are testing against Typescript classes and modules, not Vue components, and I'm trying to use jest.mock() there and getting this error.

Test suite failed to run
Do not import '@jest/globals' outside of the Jest test environment

This error seems to have started with babel-jest@^25, and can be resolved by rolling back that package to v21.2. However, there are multiple potential issues with doing that, as I don't want to use different versions of babel/babel-jest/ts-jest and also vue-test-utils-next wants babel-jest@^25.2.3.

Has anyone here seen this before and possibly know a better way to resolve it?

Here is my jest config if that helps.

module.exports = {
  preset: "@vue/cli-plugin-unit-jest/presets/typescript-and-babel",
  collectCoverage: true,
  collectCoverageFrom: ["src/**/*.{ts,tsx}", "!src/**/*.d.ts", "!src/main.ts"],
  coverageReporters: ["text", "cobertura"],
  globals: {
    "ts-jest": {
      babelConfig: true
    }
  },
  transformIgnorePatterns: [
    "/node_modules/(?!(vuetify|@tgcs|roboto-fontface|material-design-icons-iconfont|@mdi))"
  ],
  transform: {
    "^.+\\.(ts|tsx)?$": "ts-jest",
  },
  rootDir: path.resolve(process.cwd(),"."),
  testMatch: [
    "**/tests/unit/*.(ts|tsx)",
    "**/tests/unit/**/*.(ts|tsx)",
    "**/__tests__/*.spec.(ts|tsx)"
  ],
  modulePathIgnorePatterns: [
    "<rootDir>/\.yalc/@tgcs/.*/\.yalc"
  ]
};

Thanks in advance.

I have not seen that error before. I don't think it is relate to test utils (not clear what you mean by mocks in the global scope messing up things).

You will need to post a full reproduction if you want help, there is no way to reproduce the error with just your jest.config.

Most likely you have installed two jest versions because of version conflict.
In this case stack trace should have path with double "node_modules", e.g. .../node_modules/.../node_modules/...
