### Question:
ConceptsByPatient extends ConceptAction { @Override Concepts get() throws ObservationController.LoadObservationException { return controller.getConceptWithObservations(patientUuid); } ConceptsByPatient(ConceptController conceptController, ObservationController controller, String patientUuid); @Override String toString();  }### Answer:
@Test public void shouldGetObservationsByPatientUUID() throws ObservationController.LoadObservationException { ObservationController controller = mock(ObservationController.class); ConceptController conceptController = mock(ConceptController.class); ConceptsByPatient byPatient = new ConceptsByPatient(conceptController,controller, "uuid"); byPatient.get(); verify(controller).getConceptWithObservations("uuid"); }
