### Question:
ConditionalUniqueColumnCombinationResult implements RankingResult { public boolean equals(Object obj) { if (this == obj) { return true; } if (obj == null) { return false; } if (getClass() != obj.getClass()) { return false; } ConditionalUniqueColumnCombinationResult other = (ConditionalUniqueColumnCombinationResult) obj; return this.result.equals(other.getResult()); } ConditionalUniqueColumnCombinationResult();  ConditionalUniqueColumnCombinationResult(ConditionalUniqueColumnCombination result); ConditionalUniqueColumnCombination getResult(); void setResult(ConditionalUniqueColumnCombination result); ColumnCombination getColumnCombination(); ColumnCondition getCondition(); String getTableName(); void setTableName(String tableName); float getColumnRatio(); void setColumnRatio(float columnRatio); float getOccurrenceRatio(); void setOccurrenceRatio(float occurrenceRatio); float getUniquenessRatio(); void setUniquenessRatio(float uniquenessRatio); boolean equals(Object obj); @Override int hashCode();  }### Answer:
@Test public void testEquals() throws InputGenerationException, InputIterationException { ColumnIdentifier column1 = new ColumnIdentifier("table1", "column3"); ColumnIdentifier column2 = new ColumnIdentifier("table1", "column4"); ColumnConditionOr orCondition = new ColumnConditionOr( new ColumnConditionAnd(new ColumnConditionValue(column1, "condition1"), new ColumnConditionValue(column2, "condition2"))); ConditionalUniqueColumnCombination result1 = new ConditionalUniqueColumnCombination( new ColumnCombination(column1), orCondition ); ConditionalUniqueColumnCombination result2 = new ConditionalUniqueColumnCombination( new ColumnCombination(column1, column2), orCondition ); ConditionalUniqueColumnCombinationResult rankingResult1 = new ConditionalUniqueColumnCombinationResult(result1); ConditionalUniqueColumnCombinationResult rankingResult2 = new ConditionalUniqueColumnCombinationResult(result2); assertEquals(rankingResult1, rankingResult1); assertNotEquals(rankingResult1, rankingResult2); }
