How to get response from axios in offline test with local mock JSON

First off all thank you for reading this. I'm testing React app and I'm having some issues. I have a test:

import axios from'axios'
import 'babel-polyfill' -> imported because test throws error  ReferenceError: regeneratorRuntime is not defined

 function get(){
    return  axios.get('here I want to pass mock JSON file @public/mock/test.json How can I achieve this?')
}

describe('test simple GET', () => {
    it('simple key',  async () => {
        expect(
          await get().then(res =>  {
            console.log(res.data);
            return res.data
            }).catch(e=> console.log(e))
        ).toEqual(
            {
                //here is empty object because response is *undefined*
            }
        )
    })
})

I want to pass a mock JSON file @public/mock/test.json as an axios URL, is it even possible? How can I achieve it? In request config I see URL: 'http:/.public/mock/test.json', how can I overcome axios using HTTP.

I couldn't find accurate answer on web. Tried adding async/await. Also I'm having some problems with getting mock JSON. Thanks in advance for help.
