Datasource acceptance tests


I have created a very simple provider with no resources, just one datasource.
The idea is to pull data from the deployed environment, therefore I’d like an acceptance test to prove to me I can pull that data from the real environment.

With debug statements I can see my provider running and the data being pulled from the API, but I cannot write any Check that works in my Test.
All tests seem to be predicated on a resource, can’t find a way to access the data source and check the presence and content of fields.

Am I missing something, or is this just not catered for?
