### Question:
ParseBool implements IsParser<Boolean> { @Override public void setCell(Boolean o, Cell cell, Field field) { if (o != null) { cell.setCellValue(o); } }  @Override Boolean parse(Object o, Field field); @Override void setCell(Boolean o, Cell cell, Field field);  }### Answer:
@Test public void setCell() throws Exception { Cell cell = CellGenerateUtil.create(); parseBool.setCell(null, cell, null); assertEquals("", cell.getStringCellValue()); parseBool.setCell(true, cell, null); assertEquals(true, cell.getBooleanCellValue()); }
