如何使用WebDriver和Java使用TestNg框架和Apache poi在Excel中編寫數據

Question

我想在Excel中存儲用戶名和密碼，無論我將在使用WebDriver的任何應用程序中輸入什麼內容。我使用TestNg框架和Apache poi將數據寫入Excel。但我得到Null pointer exception。請告訴我如何在Excel中使用WebDriver。

public class Test { 

    private static WebDriver driver; 
    static String username="abc"; 
    static String password="abf123"; 

    public static void main(String args[]) { 
     try { 
      driver.get("any url"); 

      driver.findElement(By.xpath("//*[@id='txtUserName']")).sendKeys(username); 

      driver.findElement(By.xpath("//*[@id='txtPwd']")).sendKeys(password); 

      FileOutputStream fos = new FileOutputStream("Userpass.xls"); 

      HSSFWorkbook workbook = new HSSFWorkbook(); 

      HSSFSheet worksheet = workbook.createSheet("POI WorkSheet"); 

      HSSFRow row1 = worksheet.createRow((short) 0); 

      HSSFCell cell1 = row1.createCell((short) 0); 

      cell1.setCellValue(username); 

      HSSFCell cell2 = row1.createCell((short) 1); 

      cell2.setCellValue(password); 

      workbook.write(fos); 

      fos.close(); 

     } catch (FileNotFoundException e) { 

      e.printStackTrace(); 

     } catch (IOException e) { 

      e.printStackTrace(); 
     } 
    } 
    @Test 
    public void f() { 
    } 
}

在你的代碼

HSSFRow row1 = worksheet.createRow((short) 0); 
HSSFCell cell1 = row1.createCell((short) 0); 
cell1.setCellValue(username); 
HSSFCell cell2 = row1.createCell((short) 1); 
cell2.setCellValue(password); 

更換以下幾行

HSSFRow row1 = worksheet.createRow(0); 
row1.createCell(0).setCellValue(new HSSFRichTextString("username")); 
row1.createCell(1).setCellValue(new HSSFRichTextString("password")); 

你會得到所需的輸出。
