### Question:
OrderDependencyResult implements RankingResult { public boolean equals(Object obj) { if (this == obj) { return true; } if (obj == null) { return false; } if (getClass() != obj.getClass()) { return false; } OrderDependencyResult other = (OrderDependencyResult) obj; return this.result.equals(other.getResult()); } OrderDependencyResult();  OrderDependencyResult(OrderDependency result); OrderDependency getResult(); void setResult(OrderDependency result); OrderDependency.ComparisonOperator getComparisonOperator(); ColumnPermutation getLhs(); OrderDependency.OrderType getOrderType(); ColumnPermutation getRhs(); String getLhsTableName(); void setLhsTableName(String lhsTableName); String getRhsTableName(); void setRhsTableName(String rhsTableName); float getLhsColumnRatio(); void setLhsColumnRatio(float lhsColumnRatio); float getRhsColumnRatio(); void setRhsColumnRatio(float rhsColumnRatio); float getGeneralCoverage(); void setGeneralCoverage(float generalCoverage); float getLhsOccurrenceRatio(); void setLhsOccurrenceRatio(float lhsOccurrenceRatio); float getRhsOccurrenceRatio(); void setRhsOccurrenceRatio(float rhsOccurrenceRatio); float getLhsUniquenessRatio(); void setLhsUniquenessRatio(float lhsUniquenessRatio); float getRhsUniquenessRatio(); void setRhsUniquenessRatio(float rhsUniquenessRatio); boolean equals(Object obj); @Override int hashCode();  }### Answer:
@Test public void testEquals() throws InputGenerationException, InputIterationException { ColumnIdentifier column1 = new ColumnIdentifier("table2", "column1"); ColumnIdentifier column2 = new ColumnIdentifier("table2", "column2"); ColumnIdentifier column3 = new ColumnIdentifier("table1", "column3"); ColumnPermutation lhs1 = new ColumnPermutation(column1, column2); ColumnPermutation lhs2 = new ColumnPermutation(column1); ColumnPermutation rhs1 = new ColumnPermutation(column3); ColumnPermutation rhs2 = new ColumnPermutation(column2, column3); OrderDependency.OrderType orderType = OrderDependency.OrderType.LEXICOGRAPHICAL; OrderDependency.ComparisonOperator comparisonOperator = OrderDependency.ComparisonOperator.SMALLER_EQUAL; OrderDependency result1 = new OrderDependency(lhs1, rhs1, orderType, comparisonOperator); OrderDependency result2 = new OrderDependency(lhs2, rhs2, orderType, comparisonOperator); OrderDependencyResult rankingResult1 = new OrderDependencyResult(result1); OrderDependencyResult rankingResult2 = new OrderDependencyResult(result2); assertEquals(rankingResult1, rankingResult1); assertNotEquals(rankingResult1, rankingResult2); }
