### Question:
ParseEnum implements IsParser<Enum> { @Override public void setCell(Enum o, Cell cell, Field field) { if (o != null) { cell.setCellValue(o.name()); } }  @Override Enum parse(Object o, Field field); @Override void setCell(Enum o, Cell cell, Field field);  }### Answer:
@Test public void setCell() throws Exception { Cell cell = CellGenerateUtil.create(); parseEnum.setCell(null, cell, null); assertEquals("", cell.getStringCellValue()); parseEnum.setCell(SAMPLE_ENUM.SECOND, cell, null); assertEquals(SAMPLE_ENUM.SECOND.name(), cell.getStringCellValue()); }
