### Question:
DetectorServiceImpl implements DetectorService { @Override public void toggleDetector(String uuid, Boolean enabled) { Detector detector = repository.findByUuid(uuid); detector.setEnabled(enabled); repository.save(detector); }  @Override UUID createDetector(Detector detector); @Override Detector findByUuid(String uuid); @Override List<Detector> findByCreatedBy(String user); @Override void toggleDetector(String uuid, Boolean enabled); @Override void trustDetector(String uuid, Boolean trusted); @Override List<Detector> getLastUpdatedDetectors(long interval); @Override List<Detector> getLastUsedDetectors(int noOfDays); @Override List<Detector> getDetectorsToBeTrained(long timestampMs); @Override void updateDetector(String uuid, Detector detector); @Override void updateDetectorLastUsed(String uuid); @Override void updateDetectorTrainingTime(String uuid, long nextRun); @Override void deleteDetector(String uuid);  }### Answer:
@Test public void testToggleDetector() { serviceUnderTest.toggleDetector(someUuid.toString(), true); verify(repository, times(1)).findByUuid(someUuid.toString()); verify(repository, times(1)).save(legalParamsDetector); }
