数据驱动框架——如何使用 Selenium WebDriver 和 java 在 excel 表中读写

Question

在这里，我正在使用此代码进行阅读，并且我想在同一张纸上写出来.......我想根据将输出放在相关字段如何阅读和写现有的excel表？ 1

如何使用 Selenium WebDriver 将数据写入 Excel 文件？

@Test(priority=1)
public void Shift() throws Exception {
String dupshiftname=Skadmin.getData(62, 1);
String validshiftname=Skadmin.getData(63, 1);    

driver.findElement(By.linkText("ADMIN")).click();
driver.findElement(By.id("sessionname")).sendKeys(dupshiftname);
if (actualTitle19.contentEquals(expectedTitle19)){
System.out.println("2.Test Passed!-Submitting without shift name alert      displayed as[Shift name is required]");

//这里我希望将上面的输出写在特定单元格的 excel 表上 }

public static String getData(int r, int c) throws EncryptedDocumentException,   InvalidFormatException, IOException
{    
FileInputStream FIS=new FileInputStream("G://workspace//sample pro//src//testData//excel.xlsx");
  Workbook WB=WorkbookFactory.create(FIS);

DataFormatter formatter = new DataFormatter(); //creating formatter using the default locale
Cell cell = WB.getSheet("Sheet1").getRow(r).getCell(c);
String str = formatter.formatCellValue(cell); //Returns the formatted value  of a cell as a String regardless of the cell type.

return str;
}

使用java读取和写入excel文件，你需要api（Apache POI）

读取excel文件的代码：

public class ReadExcel 
{
    public static void main(String[] args) 
    {
        try
        {
            FileInputStream file = new FileInputStream(new File("path\\to\\excel\\file.xlsx"));

            //Create Workbook instance holding reference to .xlsx file
            XSSFWorkbook workbook = new XSSFWorkbook(file);

            //Get first/desired sheet from the workbook
            XSSFSheet sheet = workbook.getSheetAt(0);

            //Iterate through each rows one by one
            Iterator<Row> rowIterator = sheet.iterator();
            while (rowIterator.hasNext()) 
            {
                Row row = rowIterator.next();
                //For each row, iterate through all the columns
                Iterator<Cell> cellIterator = row.cellIterator();

                while (cellIterator.hasNext()) 
                {
                    Cell cell = cellIterator.next();
                    //Check the cell type and format accordingly
                    switch (cell.getCellType()) 
                    {
                        case Cell.CELL_TYPE_NUMERIC:
                            System.out.print(cell.getNumericCellValue() + "t");
                            break;
                        case Cell.CELL_TYPE_STRING:
                            System.out.print(cell.getStringCellValue() + "t");
                            break;
                    }
                }
                System.out.println("");
            }
            file.close();
        } 
        catch (Exception e) 
        {
            e.printStackTrace();
        }
    }
}

希望对你有帮助

在 Excel 表格中编写的代码。

代码：

public class WriteExcelDemo 
{
    public static void main(String[] args) 
    {
        //Blank workbook
        XSSFWorkbook workbook = new XSSFWorkbook(); 

        //Create a blank sheet
        XSSFSheet sheet = workbook.createSheet("Employee Data");

        //This data needs to be written (Object[])
        Map<String, Object[]> data = new TreeMap<String, Object[]>();
        data.put("1", new Object[] {"ID", "NAME", "LASTNAME"});
        data.put("2", new Object[] {1, "Amit", "Shukla"});
        data.put("3", new Object[] {2, "Lokesh", "Gupta"});
        data.put("4", new Object[] {3, "John", "Adwards"});
        data.put("5", new Object[] {4, "Brian", "Schultz"});

        //Iterate over data and write to sheet
        Set<String> keyset = data.keySet();
        int rownum = 0;
        for (String key : keyset)
        {
            Row row = sheet.createRow(rownum++);
            Object [] objArr = data.get(key);
            int cellnum = 0;
            for (Object obj : objArr)
            {
               Cell cell = row.createCell(cellnum++);
               if(obj instanceof String)
                    cell.setCellValue((String)obj);
                else if(obj instanceof Integer)
                    cell.setCellValue((Integer)obj);
            }
        }
        try
        {
            //Write the workbook in file system
            FileOutputStream out = new FileOutputStream(new File("howtodoinjava_demo.xlsx"));
            workbook.write(out);
            out.close();
            System.out.println("howtodoinjava_demo.xlsx written successfully on disk.");
        } 
        catch (Exception e) 
        {
            e.printStackTrace();
        }
    }
}

给你。
