[Feature]: Add code coverage into project

[aiakide]

✏️ Problem Description

That's not a problem. It would be a nice addition to the project.

💡 Feature Request

It would be nice to get a coverage badge in the README. To improve code quality, a test coverage report in a pull request would be nice.

Example: https://github.com/marketplace/actions/pytest-coverage-comment

🌍 Context

A coverage report within a pull request could motivate developers to write more tests.
