jest is not defined

While trying to use this package i receive this error:

ReferenceError: jest is not defined
    at Object.<anonymous> (/myProject/node_modules/jest-fetch-mock/src/index.js:49:15)

Do you have any idea how to fix this? Is this related to this project peer-dependencies?

Thanks in advance!

I have the same error.

package versions:

jest: v24.9.0
jest-fetch-mock: v2.1.2

jest.config.js (left details out, can reproduce with just this)

module.exports = {
  globalSetup: './tests/jest-setup.js'

tests/jest-setup.js

const fetch = require('jest-fetch-mock')

// details left out - error throw inside `jest-fetch-mock` with just this

The error occurs inside jest-fetch-mock/src/index.js on line 49. There is a reference to jest but no import for it.

seems it should be

 setupFiles: [
    './__test__/jest-setup.ts'
  ],

not globalSetup

Had this after upgrading to Next 11. My setup had collocated test & implementation files which I had working via webpack’s IgnoreLoader plugin. This plugin had a breaking change in Webpack 5.

config.plugins.push(new webpack.IgnorePlugin(/\.(e2e|spec).(ts|tsx)$/))

to

config.plugins.push(new webpack.IgnorePlugin({ resourceRegExp: /\.(e2e|spec).(ts|tsx)$/ }))
