How to run npm test

I had created a new language(React Js) code snippet. But I am unable to run the npm test command
I am getting this error
Error: Cannot find module './newmanResponses.json’
Require stack:

    }
    I had tried to find this error but unable to find anything. Can anyone help me understand what must be included in /newmanResponses.json in order to run the npm test command?
