Thanks for creating and maintaining the pytest operator, it makes integration tests much easier! This is a fairly broad feature request (or potentially a bug report). Recently I have been testing a charm on kubernetes that depends on another charm that can only run on lxd. The first thing I tried was to have a controller running on lxd and use add-k8s to also get the lxd controller to manage the kubernetes charm. Then I used the --cloud and --controller parameters to request pytest operator to use the lxd controller and kubernetes cloud. This resulted in the following error (I also tried this on GitHub actions with the same result, it looks like some weird unauthorized error):

ERROR:   integration: commands failed

I was able to deploy charms to the kubernetes controlled from lxd fine using normal juju commands.

What I got working was to have the integration tests run on a separate microk8s controller and use cross-model and cross-controller relations. However, this required the use of ops_test.juju because I could not find a way to create the relations natively e.g. using ops_test.model.relate if the relation is on another model (and in this case the model is on another controller).
