    title 'Valid Create or Update Coverage Information cards or system actions received'
    id :crd_create_or_update_coverage_info_response_validation
    description %(
      This test validates the Create or Update Coverage Information cards or system actions received from the
      CRD service, as per the specifications outlined in the [Da Vinci CRD Implementation Guide](https://hl7.org/fhir/us/davinci-crd/STU2/cards.html#create-or-update-coverage-information).

      - **Checking for Presence:**
        The test first checks if any Create or Update Coverage Information cards or system actions are present in
        the returned valid cards or valid system actions.
        - **For cards**: it ensures there are cards with a `suggestions` array containing a single suggestion,
        and the `actions` array of that suggestion has one `create` or `update` action for the `Coverage` resource.
        - **For system actions**: it checks for the presence of `create` or `update` actions for the `Coverage`
        resource.

      - **Validating:**
      If any Create or Update Coverage Information cards or system actions are found, each `Coverage` resource is
      validated against the base FHIR Coverage resource.

      If no Create or Update Coverage Information cards or system actions are received, the test is skipped.
