I looked for examples of how to extend the unit tests to cover setting up the HTTP Connection with TLS Config but was unable to find any example.

I am more than happy to add tests, I would just need a pointer in the right direction.

The only way to cover it is using e2e tests because unit tests doesn't tests http configurations yet, so no worries
