Why does my test not work when splitting mocking and stubbing?

Question

I struggle with Spock/Groovy testing. Don't know why but in WHEN section, I cannot check number of calls and checking the value at once.. If I check one of them separatly all works fine!

This test passed:

def "should throw AppointmentNotFoundException when appointment do not exist" () {
  given:
  long nonExistingAppointmentId = 69L

  when:
  appointmentRepository.findById(nonExistingAppointmentId) >> { throw new AppointmentNotFoundException("Appointment with id " + nonExistingAppointmentId + " not found") }
  findAppointmentQueryHandler.handle(nonExistingAppointmentId)

  then:
  thrown(AppointmentNotFoundException)
}

Also this one passed without any problem:

def "should throw AppointmentNotFoundException when appointment do not exist" () {
  given:
  long nonExistingAppointmentId = 69L

  when:
  appointmentRepository.findById(nonExistingAppointmentId) >> { throw new AppointmentNotFoundException("Appointment with id " + nonExistingAppointmentId + " not found") }
  findAppointmentQueryHandler.handle(nonExistingAppointmentId)

  then:
  1 * appointmentRepository.findById(69L)
}

But if I try to make 1 test to check all of it then I have error

def "should throw AppointmentNotFoundException when appointment do not exist" () {
  given:
  long nonExistingAppointmentId = 69L

  when:
  appointmentRepository.findById(nonExistingAppointmentId) >> { throw new AppointmentNotFoundException("Appointment with id " + nonExistingAppointmentId + " not found") }
  findAppointmentQueryHandler.handle(nonExistingAppointmentId)

  then:
  1 * appointmentRepository.findById(69L)
  thrown(AppointmentNotFoundException)
}

Error:

Expected exception of type 'com.bbc.anotherhospital.exceptions.AppointmentNotFoundException', but no exception was thrown
    at org.spockframework.lang.SpecInternals.checkExceptionThrown(SpecInternals.java:84)
    at org.spockframework.lang.SpecInternals.thrownImpl(SpecInternals.java:71)
    at com.bbc.anotherhospital.appointment.handlers.FindAppointmentQueryHandlerSpec.should throw AppointmentNotFoundException when appointment do not exist

First I think that I have problem in my code or smth.. But application works fine, tested in Postman.

Anybody have idea why is it behaving this way?

My pom:

I had to add things so I could run your examples, but does:

class TestSpec extends Specification {

    def "should throw AppointmentNotFoundException when appointment do not exist" () {
        given:
        AppointmentRepository appointmentRepository = Mock()
        FindAppointmentQueryHandler findAppointmentQueryHandler = new FindAppointmentQueryHandler(appRepository: appointmentRepository)
        long nonExistingAppointmentId = 69L

        when:
        findAppointmentQueryHandler.handle(nonExistingAppointmentId)

        then:
        def ex = thrown(AppointmentNotFoundException)
        ex.message == "Appointment with id $nonExistingAppointmentId not found"

        1 * appointmentRepository.findById(69L) >> {
            throw new AppointmentNotFoundException("Appointment with id " + nonExistingAppointmentId + " not found")
        }
    }

    static class FindAppointmentQueryHandler {

        AppointmentRepository appRepository

        String handle(long id) {
            appRepository.findById(id)
        }
    }

    static class AppointmentRepository {

        String findById(long id) {
            "called $id"
        }
    }

    static class AppointmentNotFoundException extends RuntimeException {

        AppointmentNotFoundException(String message) {
            super(message)
        }
    }
}

work?
