### Question:
Fun implements FunctionalDependencyAlgorithm, RelationalInputParameterAlgorithm { @Override public void execute() throws InputGenerationException, InputIterationException, CouldNotReceiveResultException, AlgorithmConfigurationException, ColumnNameMismatchException { RelationalInput input = inputGenerator.generateNewCopy(); PLIBuilder pliBuilder = new PLIBuilder(input); List<PositionListIndex> pliList = pliBuilder.getPLIList(); this.fun = new FunAlgorithm(input.relationName(), input.columnNames(), this.resultReceiver); this.fun.run(pliList); }  @Override ArrayList<ConfigurationRequirement<?>> getConfigurationRequirements(); @Override void setRelationalInputConfigurationValue(String identifier, RelationalInputGenerator... values); @Override void execute(); @Override void setResultReceiver(FunctionalDependencyResultReceiver resultReceiver); @Override String getAuthors(); @Override String getDescription();  }### Answer:
@Test public void testExecute() throws InputGenerationException, InputIterationException, CouldNotReceiveResultException, AlgorithmConfigurationException, ColumnNameMismatchException { AlgorithmTestFixture fixture = new AlgorithmTestFixture(); algorithm.setRelationalInputConfigurationValue(Fun.INPUT_FILE_TAG, fixture.getInputGenerator()); algorithm.setResultReceiver(fixture.getFunctionalDependencyResultReceiver()); algorithm.execute(); fixture.verifyFunctionalDependencyResultReceiver(); }
