This epic is the list of issues identified through testing and [feedback](https://gitlab.com/gitlab-org/gitlab/-/issues/222706) from Engineering Optimization that will let us use the [Fail Fast Testing template](https://docs.gitlab.com/ee/user/project/merge_requests/fail_fast_testing.html) and/or the [TestFileFinder gem](https://gitlab.com/gitlab-org/ci-cd/test_file_finder/) in the main gitlab project. To accomplish this the following outcomes will need to be accomplished: 1. Learn if the gem can be integrated directly into the rspec job of the test stage for a project to get the logic working and better evaluate wall clock and runner time savings. 1. [Make the test file mapping configurable](https://gitlab.com/gitlab-org/ci-cd/test_file_finder/-/issues/8) so the template can be usable in the respec foss-impact job and reduce runner minutes and pipeline wall clock time (when there is a failing test). 1. [Incorporate coverage detection for Ruby](https://gitlab.com/gitlab-org/ci-cd/test_file_finder/-/issues/9) to improve detection of minimal relevant rspec tests to run for MR pipelines in the gitlab project to reduce wall clock and runner minutes for pipelines. 1. [Incorporate coverage detection for additional languages](https://gitlab.com/gitlab-org/ci-cd/test_file_finder/-/issues/10) to extend that functionality to additional gitlab projects through the template.
