Increase Code Coverage for Existing Plugin Functionality

[zacdezgeo]

Improving the test coverage of the plugin's existing functionality is essential to ensure stability and reliability. This issue focuses on identifying areas of the codebase with low or no test coverage and implementing unit and integration tests where needed.

Task Requirements

1. Analyze Current Test Coverage (Add code coverage reporting to CI #186):

   • Use a tool such as pytest-cov to generate a coverage report.
   • Identify untested or under-tested areas of the codebase.

2. Prioritize Critical Code Paths:

   • Focus on core functionalities such as plugin initialization, configuration, and any user-facing features.

3. Write Unit Tests:

   • Add tests for standalone functions, modules, and classes that currently lack coverage.

4. Add Integration Tests:

   • Test workflows that simulate real-world plugin usage, ensuring key functionalities work together seamlessly.

5. Integrate Coverage Metrics:

   • Update the CI pipeline to include coverage metrics and enforce a minimum coverage threshold (e.g., 80%).

6. Update Documentation:

   • Document how to run tests locally and how contributors can check and improve coverage.
