- Added new modules, Improved code organization and Testing infrastructure                           

• Added unit tests in tests/ folder for configuration, database, and logging
• Reconfigured logging system to store logs in tests/logs/ directory
• Added tests/README.md with documentation on the test suite
• Added .gitignore file to exclude temporary and generated files
• Fixed test failures due to mocking issues with logging

UNIT TESTING LOGS::

TDD Passing Logs also dumped into the folder under /tests/logs/*.log

⎿ /Users/akram_personal/AKRAM_CODE_FOLDER/ANS/testvenv/lib/python3.12/site-packages/pytest_asyncio/plugin.py:217: PytestDeprecationWarning: The
configuration option "asyncio_default_fixture_loop_scope" is unset.
The event loop scope for asynchronous fixtures will default to the fixture caching scope. Future versions of pytest-asyncio will default the loop scope
for asynchronous fixtures to function scope. Set the default fixture loop scope explicitly in order to avoid unexpected behavior in the future. Valid
fixture loop scopes are: "function", "class", "module", "package", "session"
