PR Summary

• Enhancements to GitHub Actions Workflow
  The workflow now includes a new step to run tests with an additional feature to measure and understand which parts of the code are being tested. This helps to identify any code that is not being covered by tests. This information will be uploaded, creating a summary badge that can be seen on GitHub for a quick understanding of test coverage. It also now features a step to add a comment in the pull request with the results of this operation.

• New Files Added for Test Coverage Data

  Two new files have been included:

  1. .coverage: This stores data related to test coverage.
  2. coverage.xml: This is a detailed report in XML format providing information about the extent of code that our tests are covering.

• Updated Project Configuration

  The pyproject.toml file, which contains project configuration details, has been modified to include a specific tool for test coverage. This new tool is essential for the enhanced testing and coverage operations introduced in this pull request.
