CircleCI has an impressive range of tools supported for uploading test results, but Karate is not in that list. The options provided(Maven, or artifact upload), do not provide a tab where the user can navigate to and immediately see test results. As Karate generates an HTML report by default, adding better HTML integration would be a great way to go, an integration that does not require sifting through all the files used to generate the report, but simply consumes those files, and generates the report directly.
