Given the Test Description: "The system under test MUST support booking appointments by schedule reference."

Given the Preconditions: A Slot resource must have been created manually with the following properties:

• Status: free
• Name:
• Start time: 31.1.2027 11:05 (or set your own value in the configuration variable 'appointment-book-by-schedule-datetime-start' - must be in the future)
• End time: 31.1.2027 11:55 (or set your own value in the configuration variable 'appointment-book-by-schedule-datetime-end' - must be in the future)
• Treatment type: same as from the Schedule-Read test case

Given TGR set default header "Content-Type" to "application/fhir+json"

And TGR send POST request to "http://fhirserver/Appointment/$book" with body "!{file('src/test/resources/features/Stufe5/Terminplanung/fixtures/Appointment-Appointment-Book-By-Schedule-Parameters-Fixture.json')}"

Then TGR find the last request

And TGR current response with attribute "$.responseCode" matches "20\d"

And FHIR current response body evaluates the FHIRPath '($this is Appointment) or ($this is Parameters)' with error message 'The response contains neither an Appointment nor an OperationOutcome resource nor a Parameters resource'

And FHIR current response body evaluates the FHIRPath '($this is Appointment) implies id.exists()' with error message 'Response variant Appointment: no ID was assigned to the appointment'

And FHIR current response body evaluates the FHIRPath "($this is Appointment) implies status.toString().matches('^booked|pending$')" with error message 'Response variant Appointment: no ID was assigned to the appointment'

And FHIR current response body evaluates the FHIRPath "($this is Appointment) implies slot.exists()" with error message 'Response variant Appointment: no slot assigned'

And FHIR current response body evaluates the FHIRPath "($this is Parameters) implies parameter.where(name = 'return' and resource is Appointment).resource.id.exists()" with error message 'Response variant Parameters: no ID was assigned to the appointment'

And FHIR current response body evaluates the FHIRPath "($this is Parameters) implies parameter.where(name = 'return' and resource is Appointment).resource.status.toString().matches('^booked|pending$')" with error message 'Response variant Parameters: the appointment status is neither booked nor pending'

And FHIR current response body evaluates the FHIRPath "($this is Parameters) implies parameter.where(name = 'return' and resource is Appointment).resource.slot.exists()" with error message 'Response variant Parameters: no slot assigned'
