This can also be addressed iteratively, module by module, and can therefore be assigned to multiple people. In that case, open a separate issue for the module that you want to write tests for and link to this issue.

Hi @uniqueg ,
I would love to work on this issue. I have prior experience using Pytest and am willing to learn new techniques as needed.
Thank you

Thanks @SohamRatnaparkhi. Given that there's a lot of code that needs to be tested, I would suggest that you pick one module and open an issue for that and link it here. We can then assign you to that issue.
