Tackle the issue of lacking unit tests in PorQua, making PorQua more reliable for financial optimization.

In the existing test file test/tests_quadratic_program.py, the parameters universe, params, and solver are lacking for the TestLeastSquare function, this needs further implementation.

Hi @pingluuu ,

I have implemented comprehensive unit test framework in #29. It addresses the need for improved test coverage and reliability by introducing:

• A structured pytest framework for automated testing.
• GitHub Actions integration for continuous testing.
• Unit tests for optimization algorithms, data handling, and backtesting functions.
• Performance and edge case tests to ensure numerical stability.
• Improved code coverage enforcement using pytest-cov and documentation for testing workflows.

It's my small contribution to PorQua’s and I am hoping this helps and looking forward to any feedback!

Additionally, I’m planning to submit another proposal for GSoC 2025, and I hope this work demonstrates my commitment to contributing meaningfully to the project.
