### Question:
ClassificationServiceImpl implements ClassificationService { @Override public ClassificationQuery createClassificationQuery() { return new ClassificationQueryImpl(taskanaEngine); } ClassificationServiceImpl(
      InternalTaskanaEngine taskanaEngine,
      ClassificationMapper classificationMapper,
      TaskMapper taskMapper); @Override Classification getClassification(String key, String domain); @Override Classification getClassification(String id); @Override void deleteClassification(String classificationId); @Override void deleteClassification(String classificationKey, String domain); @Override Classification createClassification(Classification classification); @Override Classification updateClassification(Classification classification); @Override ClassificationQuery createClassificationQuery(); @Override Classification newClassification(String key, String domain, String type);  }### Answer:
@Test void testCreateClassificationQuery() { cutSpy.createClassificationQuery(); verify(internalTaskanaEngineMock, times(1)).getHistoryEventManager(); verifyNoMoreInteractions( classificationMapperMock, internalTaskanaEngineMock, taskanaEngineMock, classificationQueryImplMock); }
