Test Patient Compartment - resource aggregation (TestID12)

[nir-r]

Test12If a patient compartment is declared (CapabilityStatement.rest.compartment) - check it aggregates resources correctly

[nir-r]

This is based on the below from HL7.
This can only be tested on resource types that are included based on more than a single element, I.e, Procedure where a patient can be both the "patient" and \ or the "performer".

Do we need to actively find such an example to test that the patient compartment behaves exactly as the discreet calls below?

However, there is a key difference in functionality between compartment based searches and direct searches with parameters. Consider this search:

GET [base]/Patient/[id]/Communication
Because the definition of the patient compartment for Communication says that a Communication resource is in the patient compartment if the subject, sender, or recipient is the patient, the compartment search is actually the same as the union of these 3 searches:

GET [base]/Communication?subject=[id]
GET [base]/Communication?sender=[id]
GET [base]/Communication?recipient=[id]
There is no way to do this as a single search, except by using the _filter:
