Selenium：切换到下一个文档以读取 excel 时出现“StaleElementReferenceException”

如何解决Selenium：切换到下一个文档以读取 excel 时出现“StaleElementReferenceException”

必须处理多个文档，以验证文本框中的所有输入是否正确。为此，我从 Excel 工作表中获取数据，并且必须将数据与文本框中的数据进行比较。 当我切换到下一个文档时能够将它与第一个文档进行比较我得到 org.openqa.selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document. 它不是从第二个文档文本框中读取数据。

@Test(priority=4,dataProvider="getTestData")
public void excelUpload(String relatie,String date,String amount,String reknum,String BTW,String btwled,String totaldiff,String btwdiffamt,String bankaccnum) throws Exception {
    
    ocrupload.nextInvoice();
    
    Thread.sleep(5000);
    
    SoftAssert softAssert = new SoftAssert();
    
    String text = ocrupload.relatie();
    
    softAssert.assertEquals(text,relatie);
    
    String dat = ocrupload.datum();
    
    softAssert.assertEquals(dat,date);
    
    String totamt = ocrupload.txttotal();
    
    softAssert.assertEquals(totamt,amount);

    String reknumber = ocrupload.bankaccnumber();
    
    softAssert.assertEquals(reknumber,reknum);
    
    String btwNum = ocrupload.btwNumber();
    
    softAssert.assertEquals(btwNum,BTW);
    
    String btwledger = ocrupload.btwledger();
    
    softAssert.assertEquals(btwledger,btwled);
    
    String btwtotamount = ocrupload.btwtotal();
    
    softAssert.assertEquals(btwtotamount,totaldiff);
    
    String totaldifferance = ocrupload.btwDiffamt();
    
    softAssert.assertEquals(totaldifferance,btwdiffamt);

     softAssert.assertAll();








@DataProvider
public Object[][] getTestData(String sheetName) throws InvalidFormatException {
    FileInputStream file = null;
    try {
        file = new FileInputStream(TESTDATA_SHEET_PATH);
    } catch (FileNotFoundException e) {
        e.printstacktrace();
    }
    try {
        book = WorkbookFactory.create(file);
    } catch (IOException e) {
        e.printstacktrace();
    }
    sheet = book.getSheet(sheetName);
    Object[][] data = new Object[sheet.getLastRowNum()][sheet.getRow(0).getLastCellNum()];
    // System.out.println(sheet.getLastRowNum() + "--------" +
    // sheet.getRow(0).getLastCellNum());
    for (int i = 0; i < sheet.getLastRowNum(); i++) {
    for (int k = 0; k < sheet.getRow(0).getLastCellNum(); k++) {
        
            data[i][k] = sheet.getRow(i + 1).getCell(k).toString();
            
            
        }
    
    
    
    }
    return data;
}
