Set up testing with mocha for this project

[ezkemboi]

• In simple, we do set tests for the functions created. You can make use of mocha and running using nyc.
• If possible, we can do checks on files intended to be created when the app is created (Might need more discussion).
• Also, we can add travis and coveralls (CI/CD)
