Error encountered: "preset @vue/cli-plugin-unit-jest/presets/typescript-and-babel is missing"

I am encountering an issue with my default jest.config.js file. When I try to run a unit test, I receive the following error message:

Validation Error: Preset @vue/cli-plugin-unit-jest/presets/typescript-and-babel not found.

The technologies I am using include Vue 2 with the Composition API plugin and TypeScript.

Here is the content of my jest.config.js file:

module.exports = {
  preset: '@vue/cli-plugin-unit-jest/presets/typescript-and-babel'
}

And here is an example spec file (example.spec.ts):

import { shallowMount } from '@vue/test-utils'
import HelloWorld from '@/components/HelloWorld.vue'

describe('HelloWorld.vue', () => {
  it('renders props.msg when passed', () => {
    const msg = 'new message'
    const wrapper = shallowMount(HelloWorld, {
      props: { msg }
    })
    expect(wrapper.text()).toMatch(msg)
  })
})

Answer №1

Successfully resolved the issue by updating the jest plugin version from:

@vue/cli-plugin-unit-jest": "^3.12.1"
to:
@vue/cli-plugin-unit-jest": "^4.5.0"
