refactor(test): make sure cli tests are not internal unless they need to be (#1878)

As part of this change searchConfig needed to be exported,
as it was passed as a parameter to exported functions

At this moment most of the tests remaining internal depend on the mock service.
The interface it implements has unexported methods.
