Q: Cannot mock in Jest with ES modules I'm trying to reproduce the example given in Jest documentation about mocking module. The code is the following one.
users.js
import axios from 'axios'

class Users {
  static all () {
    return axios.get('/users.json').then(resp => resp.data)
  }
}

export default Users

test.js
import axios from 'axios'
import Users from './users'
import { jest } from '@jest/globals'
jest.mock('axios')

test('should fetch users', () => {
  const users = [ { name: 'Bob' } ]
  const resp = { data: users }
  axios.get.mockResolvedValue(resp)

  // or you could use the following depending on your use case:
  // axios.get.mockImplementation(() => Promise.resolve(resp))

  return Users.all().then(data => expect(data).toEqual(users))
})

The code from test.js is a little bit different from the documentation. I had to add import { jest } from '@jest/globals' because of this issue

When executing the test, I'm getting this as a result:
axios.get.mockResolvedValue is not a function
TypeError: axios.get.mockResolvedValue is not a function

Looks like the mock won't work. What have I missed to make it work?
