redux: Can not test async action base on redux.org tutorial

I just wonder is there demo code of the async action test on redux.org?

I tried to remake the tutorial, here is my demo: https://github.com/craigcosmo/react-redux-test

action.js

import axios from 'axios'

export function getGoodDataStart(){
    return{
        type: "GOOD_DATA_START"
    }
}
export function getGoodDataSuccess(payload){
    console.log('success', payload)
    return {
        type: "GOOD_DATA_SUCCESS",
        payload: payload
    }
}
export function getGoodDataFail(){
    return{
        type: "GOOD_DATA_FAIL"
    }
}
export function getGoodData(){
    return (dispatch) => {
        dispatch( getGoodDataStart() )
        return  axios.get('http://www.google.com/list')
            .then( response => {
                console.log('fake res',response)
                dispatch(getGoodDataSuccess (response) )
            })
            .catch( err => {
                console.log('fake err',err)
            })
    }   
}

register.test.js

import nock from 'nock'
import React from 'react'
import {expect} from 'chai'
import {getGoodData} from 'registerAction'
import configureMockStore from 'redux-mock-store'
import thunk from 'redux-thunk'

const middlewares = [ thunk ]
const mockStore = configureMockStore(middlewares)

describe('Register component', () => {

    it('async action', function () {

        nock('http://www.google.com')
        .get('/list')
        .reply(200,'ok!' )

        const store = mockStore({ 
            myData: '' ,
        })
        const expected = [
            {type: "GOOD_DATA_START"},
            {type: "GOOD_DATA_SUCCESS", payload: 'ok!'}
        ]

        return store.dispatch(getGoodData())
            .then( () => { 
                expect(store.getActions()).to.equal(expected)
            })
    })
})

The problem is, nock does not block the request as we think it would. Therefore, action actually makes the request to remote server, therefore, the result of the request is not the same as expectedResult
