In Vuex + Jest, how to unit test a getter which is calling the store?

Question

I'm trying to test the following very simple getter from my vuex store. It is simply concatenating two strings :

const getters = {
  adressToGet: state => {
    return state.baseAdress + store.getters.queryToGet
  }
 }

Mocking the state part is easy but I can't find a good way to mock the store.

If this was in a component, I could mount the component with mount or shallow and assign to it the mock store, but it isn't. This is from the vuex store.

This is my test code :

import Search from '@/store/modules/search'

jest.mock('@/store/modules/search.js')

describe('search.js', () => {

  test('The adress getter gets the right adress', () => {
    const state = {
      baseAdress: 'http://foobar.com/'
    }
    // I define store here, but how can I inject it into my tested getter ?
    const store = { 
      getters: {
        queryToGet: 'barfoo'
      }
    }
    expect(Search.getters.adressToGet(state)).toBe('http://foobar.com/barfoo')
  })
})

I get http://foobar.com/undefined instead of expected.

What would be the best way to do this ?

Edit: Following the first comment, my new version, but it still gives the same result:

import Search from '@/store/modules/search'
import { createLocalVue } from '@vue/test-utils'
import Vuex from 'vuex'

jest.mock('@/store/modules/search.js')

describe('search.js', () => {

  test('The adress getter gets the right adress', () => {
    const localVue = createLocalVue()
    localVue.use(Vuex)

    const mockState = {
      baseAdress: 'http://foobar.com/'
    }

    const store = new Vuex.Store({
      state: mockState,
      getters: {
        queryToGet: function () {
          return 'barfoo'
        }
      }
    }) 

   expect(Search.getters.adressToGet(mockState))
   .toBe('http://foobar.com/barfoo')
  })
})

After much research, I realized I had to mock the store dependency with Jest. This seems the correct way to do it and pass the test:

import Search from '@/store/modules/search'

jest.mock('@/store/index.js', () =>({
  getters: {
    queryToGet: 'barfoo'
  }
}))

jest.mock('@/store/modules/search.js')

describe('search.js', () => {
  test('The adress getter gets the right adress', () => {
    const state = {
      baseAdress: 'http://foobar.com/'
    }
    expect(Search.getters.adressToGet(state))
    .toBe('http://foobar.com/barfoo')
  })
})
