### Question:
ResultCache extends ResultReceiver { @Override public void receiveResult(BasicStatistic statistic) throws ColumnNameMismatchException { if (this.acceptedResult(statistic)) { results.add(statistic); } else { throw new ColumnNameMismatchException("The column name of the result does not match with the column names in the input!"); } } ResultCache(String algorithmExecutionIdentifier, List<ColumnIdentifier> acceptedColumns); protected  ResultCache(String algorithmExecutionIdentifier, List<ColumnIdentifier> acceptedColumns, Boolean test); @Override void receiveResult(BasicStatistic statistic); @Override void receiveResult(FunctionalDependency functionalDependency); @Override void receiveResult(MatchingDependency matchingDependency); @Override void receiveResult(ConditionalFunctionalDependency conditionalFunctionalDependency); @Override void receiveResult(MultivaluedDependency multivaluedDependency); @Override void receiveResult(InclusionDependency inclusionDependency); @Override void receiveResult(UniqueColumnCombination uniqueColumnCombination); void receiveResult(ConditionalUniqueColumnCombination conditionalUniqueColumnCombination); @Override void receiveResult(OrderDependency orderDependency); @Override void receiveResult(DenialConstraint denialConstraint); @Override void receiveResult(ConditionalInclusionDependency conditionalDependency); List<Result> fetchNewResults(); @Override void close();  }### Answer:
@Test(expected = ColumnNameMismatchException.class) public void testAcceptedResult() throws IOException, CouldNotReceiveResultException, ColumnNameMismatchException { FunctionalDependency expectedFd = new FunctionalDependency( new ColumnCombination( new ColumnIdentifier("table1", "column2")), new ColumnIdentifier("table1", "column23") ); List<ColumnIdentifier> acceptableColumnNames = new ArrayList<>(); acceptableColumnNames.add(new ColumnIdentifier("table2", "column2")); acceptableColumnNames.add(new ColumnIdentifier("table2", "column23")); ResultCache resultCache = new ResultCache("identifier", acceptableColumnNames); resultCache.setResultTestDir(); resultCache.receiveResult(expectedFd); FileUtils.deleteDirectory(new File(ResultPrinter.RESULT_TEST_DIR).getParentFile()); }
