 ## Overview
 This tool is part of a broader suite of utilities designed to automate the creation of unit tests for software projects. Utilizing advanced Generative AI models, it aims to simplify and expedite the testing process, ensuring high-quality software development. The system comprises several components:
 1. **Test Runner:** Executes the command or scripts to run the test suite and generate code coverage reports.
-2. **Coverage Parser:** Validates that code coverage is increasing as tests are added, ensuring that new tests are contributing to the overall test effectiveness.
