### Question:
FunctionalDependencyResult implements RankingResult { public boolean equals(Object obj) { if (this == obj) { return true; } if (obj == null) { return false; } if (getClass() != obj.getClass()) { return false; } FunctionalDependencyResult other = (FunctionalDependencyResult) obj; return this.result.equals(other.getResult()); } FunctionalDependencyResult();  FunctionalDependencyResult(FunctionalDependency result); FunctionalDependency getResult(); void setResult(FunctionalDependency result); ColumnCombination getDeterminant(); ColumnIdentifier getDependant(); String getDeterminantTableName(); void setDeterminantTableName(String determinantTableName); String getDependantTableName(); void setDependantTableName(String dependantTableName); ColumnCombination getExtendedDependant(); void setExtendedDependant(ColumnCombination extendedDependant); float getDependantColumnRatio(); void setDependantColumnRatio(float dependantColumnRatio); float getDeterminantColumnRatio(); void setDeterminantColumnRatio(float determinantColumnRatio); float getGeneralCoverage(); void setGeneralCoverage(float generalCoverage); float getDeterminantOccurrenceRatio(); void setDeterminantOccurrenceRatio(float determinantOccurrenceRatio); float getDependantOccurrenceRatio(); void setDependantOccurrenceRatio(float dependantOccurrenceRatio); float getDependantUniquenessRatio(); void setDependantUniquenessRatio(float dependantUniquenessRatio); float getDeterminantUniquenessRatio(); void setDeterminantUniquenessRatio(float determinantUniquenessRatio); float getPollution(); void setPollution(float pollution); String getPollutionColumn(); void setPollutionColumn(String pollutionColumn); float getInformationGainBytes(); void setInformationGainBytes(float informationGainBytes); float getInformationGainCells(); void setInformationGainCells(float informationGainCells); @JsonIgnore BitSet getDeterminantAsBitSet(); @JsonIgnore void setDeterminantAsBitSet(BitSet determinantAsBitSet); @JsonIgnore BitSet getDependantAsBitSet(); @JsonIgnore void setDependantAsBitSet(BitSet dependantAsBitSet); @JsonIgnore BitSet getExtendedDependantAsBitSet(); @JsonIgnore void setExtendedDependantAsBitSet(BitSet extendedDependantAsBitSet); boolean equals(Object obj); @Override int hashCode();  }### Answer:
@Test public void testEquals() throws InputGenerationException, InputIterationException { ColumnCombination determinant1 = new ColumnCombination(new ColumnIdentifier("table1", "column5")); ColumnIdentifier dependant1 = new ColumnIdentifier("table1", "column2"); ColumnCombination determinant2 = new ColumnCombination(new ColumnIdentifier("table2", "column3")); ColumnIdentifier dependant2 = new ColumnIdentifier("table1", "column7"); FunctionalDependency result1 = new FunctionalDependency( determinant1, dependant1 ); FunctionalDependency result2 = new FunctionalDependency( determinant2, dependant2 ); FunctionalDependencyResult rankingResult1 = new FunctionalDependencyResult(result1); FunctionalDependencyResult rankingResult2 = new FunctionalDependencyResult(result2); assertEquals(rankingResult1, rankingResult1); assertNotEquals(rankingResult1, rankingResult2); }
