Fix testing issue

[DDibyajyot]

Closes issue #16

The changes address recent test failures and other areas for improvement identified in the CI pipeline logs (CI pipeline run).

Added testing guidelines and documentation in CONTRIBUTING.md for future testing purposes.

This PR aims to maintain a clean and reliable test suite that thoroughly validates core functionality and supports further development with confidence.

@iamDyeus Hey, have a look and let me know if it looks good. I have added testing guidelines in contributing.md and made it so pytest actually works.

@DDibyajyot Everything looks great! However, I think we’ll also need to update .github/workflows/ci.yml since the current command and the one in your commit have recently changed the implementation. Please ping me once this is fixed.

[DDibyajyot]

@iamDyeus I have updated it, thank you for pointing it out to me! It should work with the new implementation now.

Interesting, I see the checks are failing, let me fix that

Yeah, you'll probably need to update upload-artifact to v3, checkout to v3, and setup-python to v4 as earlier versions are likely deprecated in ci.yml.

[DDibyajyot]

Hopefully everything should be fine, I followed your advise and updated all 3 to newer versions

The checks are confusing, I agree with the command for debug, but why has the dependency error come up when it has been there since the beginning?

The dependency error arised because I bumped the Python version from 3.8 to 3.12 in ci.yml. I think the main issue is how the workflow is trying to locate the src path. I'll take a look when I have a bit more time, but if you could try to debug and fix it in the meantime, that would be great.
