### Question:
MatchupGenerator extends BasicTool { static Matchup createMatchup(long matchupPattern, ReferenceObservation r) { final Matchup matchup = new Matchup(); matchup.setId(r.getId()); matchup.setRefObs(r); matchup.setPattern(matchupPattern); return matchup; } MatchupGenerator(); static void main(String[] args); @Override void initialize();  }### Answer:
@SuppressWarnings("deprecation") @Test public void testCreateMatchup() { final ReferenceObservation referenceObservation = new ReferenceObservation(); referenceObservation.setId(45); final Matchup matchup = MatchupGenerator.createMatchup(7765L, referenceObservation); assertNotNull(matchup); assertEquals(45, matchup.getId()); assertSame(referenceObservation, matchup.getRefObs()); assertEquals(7765L, matchup.getPattern()); }
