### Question:
ImportParseParameters extends Observable implements Cloneable { public SpecialColumn getSpecialColumn(ColumnType columnType) { SpecialColumn specialColumn = null; for (SpecialColumn column : mySpecialColumns) { if (column.getColumnType() == columnType) { specialColumn = column; break; } } return specialColumn; } ImportParseParameters(); List<? extends String> getColumnNames(); Set<SpecialColumn> getSpecialColumns(); void setColumnNames(List<? extends String> columnNames); List<Integer> getColumnsToIgnore(); void setColumnsToIgnore(List<Integer> columnsToIgnore); boolean hasCategory(final Category category); boolean hasType(final ColumnType type); boolean hasType(final ColumnType... types); boolean isColumnIncluded(SpecialColumn specialColumn, final ColumnType... types); SpecialColumn getSpecialColumn(ColumnType columnType); @Override boolean equals(Object obj); @Override int hashCode(); @Override String toString(); @Override ImportParseParameters clone();  }### Answer:
@Test public void testGetSpecialColumn() { SpecialColumn specialColumn = new SpecialColumn(0, ColumnType.DATE, DATE_FORMAT); myTestObject.getSpecialColumns().add(specialColumn); assertEquals(specialColumn, myTestObject.getSpecialColumn(ColumnType.DATE)); assertNull(myTestObject.getSpecialColumn(ColumnType.LAT)); }
