Testing and coverage for chat app

Please can you tell how to setup testing and coverage for the Chat Application Project?

@sourabhkhs23 you can read about mocha, chai and nyc through the documentation provided on the official site, all you have to do is to place the checks i.e. perform unit testing (testing the unit feature in the chat app like sending and receiving message) and code coverage

I deployed chat app on heroku. Though the app was working fine in localhost it’s not working on heroku. Probably the script.js file is not executing as the stuffs which were supposed to be hidden are not hidden.

@sourabhkhs23 what is the error that you are getting in your heroku logs. Check that and send the same here too.
