[YourAKShaw]

Add GitHub actions which will automate testing for each PR and add coverage reports, added that it should block PRs in case test coverage is ineligible.

Done @glitchpop-frenzy

[saksham-gt]

Hey @rohitg00, can you share the steps how to build the project in README or maybe here?

[YourAKShaw]

@glitchpop-frenzy kindly check the package.json for the scripts. Currently the project is only initialized and no features are added yet, although you can get an idea about build steps from the package.json. Do feel free to play around a bit.

@Ak-Shaw are we suppose to create our own action or using this https://github.com/marketplace/actions/jest-coverage-report will be fine

[YourAKShaw]

Initially, the mentioned tool should do. We might consider adding our own actions soon. No features are currently on main so it doesn't make sense to create our own action ATM.
