### Question:
Ducc implements UniqueColumnCombinationsAlgorithm, RelationalInputParameterAlgorithm,
                             BooleanParameterAlgorithm { @Override public void setResultReceiver(UniqueColumnCombinationResultReceiver receiver) { this.resultReceiver = receiver; } Ducc(); @Override ArrayList<ConfigurationRequirement<?>> getConfigurationRequirements(); @Override void setRelationalInputConfigurationValue(String identifier, RelationalInputGenerator... values); @Override void execute(); @Override void setResultReceiver(UniqueColumnCombinationResultReceiver receiver); @Override void setBooleanConfigurationValue(String identifier, Boolean... values); @Override String getAuthors(); @Override String getDescription();  }### Answer:
@Test public void testSetResultReceiverUniqueColumnCombinationResultReceiver() { UniqueColumnCombinationResultReceiver expectedResultReceiver = mock(UniqueColumnCombinationResultReceiver.class); ducc.setResultReceiver(expectedResultReceiver); assertSame(expectedResultReceiver, ducc.resultReceiver); }
