[Feature] Script for Coverage Check

[vaguecoder]

Is your feature request related to a problem? Please describe.

Currently, we only check coverage in local run with manual validation. Need to automate for CI/CD.

Describe the solution you'd like

Need a script that will fail if the expected threshold is not met. This can then be run from GitHub actions on every push or PR.

Describe alternatives you've considered

Make target would also do the trick. But as the commands grow in size, it gets a hassle to overload makefile.

Additional context

1. GitHub actions already have the unit test run workflow(s). Just need to add a separate workflow of coverage check.
2. If using a script, it should run on bash (zsh user myself, I still think bash is the standard). Syntax differences of different shells or WSL is a headache of the future developers.

Ownership of Contribution

If the triage is approved,

• I wish to submit the PR myself.
• I wish to submit the PR. But if someone is willing to do it, go ahead.
• I don't know how to fix this or make these changes. I wish others to pick this up for me.

@vaguecoder what is the minimum (%) for test coverage in that task?

[vaguecoder]

@tanryberdi Let's mark the current code coverage as the minimum. Because the ultimate aim is to maintain & keep it improving.
