### Question:
MeasurementUnitMatch extends AbstractMatcher<URI, URI> { @Override public boolean match(URI offer, URI requirement, List<MatchingResultMessage> errorLog) { return requirement == null || (requirement.toString().equals(StreamPipes.ANYTHING) && offer != null) || (offer != null && requirement.toString().equals(offer.toString())); } MeasurementUnitMatch(); @Override boolean match(URI offer, URI requirement, List<MatchingResultMessage> errorLog);  }### Answer:
@Test public void testPositiveMeasurementUnitMatch() { URI offered = URI.create("http: URI required = URI.create("http: List<MatchingResultMessage> errorLog = new ArrayList<>(); boolean matches = new MeasurementUnitMatch().match(offered, required, errorLog); assertTrue(matches); }
