資料驅動部分，是自動化測試常用部分，也是引數化設計的重要環節，前面分享了，mysql、yaml做資料來源，那麼再來分享下excel做資料驅動

思路：

先用POI讀取excel。解析讀取資料，返回list,返回Object[][]即可

工具類檔案：

讀取excel，返回map物件list集合

                        cellData = (String) getCellFormatValue(row.getCell(j));
                        map.put(columns[j], cellData);
                    }
                } else {
                    break;
                }
                list.add(map);
            }
        }
        return list;
    }


    /**

        String extString = filePath.substring(filePath.lastIndexOf("."));
        InputStream is = null;
        try {
            is = new FileInputStream(filePath);
            if (".xls".equals(extString)) {
                return wb = new HSSFWorkbook(is);
            } else if (".xlsx".equals(extString)) {
                return wb = new XSSFWorkbook(is);
            } else {
                return wb = null;
            }
        } catch (FileNotFoundException e) {

        } catch (IOException e) {
            e.printStackTrace();
        }
        return wb;
    }

    public static Object getCellFormatValue(Cell cell) {
        Object cellValue = null;
        if (cell != null) {
            //判斷cell型別
            switch (cell.getCellType()) {
                case Cell.CELL_TYPE_NUMERIC: {
                    cellValue = String.valueOf(cell.getNumericCellValue());
                    break;
                }
                case Cell.CELL_TYPE_FORMULA: {
                    //判斷cell是否為日期格式
                    if (DateUtil.isCellDateFormatted(cell)) {
                        //轉換為日期格式YYYY-mm-dd
                        cellValue = cell.getDateCellValue();
                    } else {
                        //數字
                        cellValue = String.valueOf(cell.getNumericCellValue());
                    }
                    break;
                }
                case Cell.CELL_TYPE_STRING: {
                    cellValue = cell.getRichStringCellValue().getString();
                    break;
                }
                default:
                    cellValue = "";
            }
        } else {
            cellValue = "";
        }
        return cellValue;
    }

}

然後把解析出來的list轉換成Object[][]型別的資料，且結合在@DataProvider中。

import org.testng.annotations.DataProvider;

import java.util.List;
import java.util.Map;

public class ExcelDataHeleper {
    

    @DataProvider
    public Object[][] dataMethod(){
        List<Map<String, String>> result = ReadExcelUtil.getExcuteList("D:\\data.xls");
        Object[][] files = new Object[result.size()][];
        for(int i=0; i<result.size(); i++){
            files[i] = new Object[]{result.get(i)};
        }        
        return files;
    }
    

}

再通過測試檔案來測試一下：

import org.testng.annotations.Test;

import java.util.Map;

public class TestDataUtil extends ExcelDataHeleper {


    @Test(dataProvider="dataMethod")
    public void testmethod1(Map<?, ?> param){
        System.out.println(param.get("name")+"\t"+param.get("method")+"\t"+param.get("value"));
    }


}

執行結果：
