### Question:
UniqueColumnCombination implements Result { @Override @XmlTransient public void sendResultTo(OmniscientResultReceiver resultReceiver) throws CouldNotReceiveResultException, ColumnNameMismatchException { resultReceiver.receiveResult(this); } protected  UniqueColumnCombination();  UniqueColumnCombination(ColumnIdentifier... columnIdentifier);  UniqueColumnCombination(ColumnCombination columnCombination); ColumnCombination getColumnCombination(); void setColumnCombination(ColumnCombination columnCombination); @Override @XmlTransient void sendResultTo(OmniscientResultReceiver resultReceiver); @Override String toString(); String toString(Map<String, String> tableMapping, Map<String, String> columnMapping); static UniqueColumnCombination fromString(Map<String, String> tableMapping, Map<String, String> columnMapping, String str); @Override int hashCode(); @Override boolean equals(Object obj);  }### Answer:
@Test public void testSendResultTo() throws CouldNotReceiveResultException, ColumnNameMismatchException { OmniscientResultReceiver resultReceiver = mock(OmniscientResultReceiver.class); UniqueColumnCombination ucc = new UniqueColumnCombination(); ucc.sendResultTo(resultReceiver); verify(resultReceiver).receiveResult(ucc); }
