Jest ES6 Error unexpected token import?

Hello how can I use ES6 with Jest. Because they send me a mistake in spread (operator) and export. How to modify jest?

export default function reducer(state={
    open:false
  }, action) {

    switch (action.type) {
      case "HANDLE_TAP_HOME": {
        return {...state,open:action.open}
        
      }
    }

    return state
}

test

import base from '../../client/src/redux/reducer/reducers/Admin/base/Index'

describe('request to Reducer',()=>{
    it('fetch',()=>{
        expect(base(undefiend,{type:'nothing'})).toEqual({
            open:false
        })
    })
})
