How to use

  1. 1

    Start by replacing [YOUR_PROJECT] with the actual name of your project to ensure the loop is tailored to your specific context in the test coverage improvement process.

  2. 2

    Run [YOUR_COVERAGE_COMMAND] with a command that matches your project's setup to accurately gather and parse the coverage data needed for the loop.

  3. 3

    After identifying files with low coverage, focus on generating targeted unit tests that align with your coding standards by customizing [YOUR_TEST_FRAMEWORK] to suit your project's requirements.
