• Add support for data mining of information.
• Add logic to provide this information to the Feature detail page.
• Add logic managing the feature coverage matrix by testing.
  • Without test headers, it shows no coverage information.
• Add logic to detect tests in the repository. - Expect strong customization to be available.
• Define the necessary configuration controls that are available to the user.

Note: Make Epic from this issue if needed and provide a solution in smaller parts.
