How to test redux API with node

I am new to both nodejs and redux. I already have node v7.10 installed on my machine. When I read the redux doc, it claims I should be able to test the action, reducer and store API without UI.

So what I want to do is try to test them in a pure nodejs program.

Here are the step, I am trying to do:

1. create my testing directory for my testing project and run npm init to create a package.json file

2. run npm install --save redux to get redux module in my testing directory

3. create a file named reducer.js with the following content:

   import { combineReducers } from 'redux';
   console.log('testing.');
   
   

However, when I try to test my script: node reducer.js, I encountered SyntaxError: Unexpected token import

SyntaxError: Unexpected token import
