读取和写入Excel文件时出现意外错误使用Selenium Webdriver

时间：2013-10-29 13:05:22

标签： excel junit selenium-webdriver

我正在使用此方法阅读

FileInputStream fi = new FileInputStream("C:\\Users\\GChaitanya.CHAINGANG\\Desktop\\2012_October_3PL_Unified_Template.xls");
Workbook w = Workbook.getWorkbook(fi);
s = w.getSheet(0);

这就是写

WritableWorkbook wb = Workbook.createWorkbook(new File("D:\\output_2.xls"));
WritableSheet ws = wb.createSheet("customsheet", 1);

我收到此错误

并在调试模式下显示

代码工作正常，但突然停止工作，几乎没有读取10条记录和崩溃。我能够阅读至少300到400条记录

这不是与读取或写入Excel文件相关的错误。您在以下行使用Selenium单击Web元素时收到错误（StaleElementReferenceException）

在gmailTest.TestLink.RealTime（TestLink.java:100）

在点击webelement之前，请确保该元素具有有效的最新引用。

查看StaleElementReferenceException http://docs.seleniumhq.org/exceptions/stale_element_reference.jsp
