我正在为GWT应用程序编写自动测试。我试着双击表格元素。我使用此代码点击：
browser.element(:xpath, '/html/body/div[5]/div[2]/div/div/div/div[2]/div/div/div/div/div/div/div/div[2]/div/div[2]/div/div/table/tbody[2]/tr[1]/td[1]/div').double_click
执行此命令时，我收到如下错误：
test_search(TC_article_example):Selenium::WebDriver::Error::InvalidElementStateError: Cannot perform native interaction: Could not load native events component.

我已将此代码添加到我的脚本中，但这没有帮助：
profile = Selenium::WebDriver::Firefox::Profile.new
profile.native_events = false
browser = Watir::Browser.new :firefox, :profile => profile
请给我一些提示。我使用 selenium 2.31 ， watir 4.0 和 firefox 19.0.2 。 PS：抱歉我的英文。
答案 0 :(得分：0)
错误听起来像是想要原生事件，而你却不允许这样做。尝试将原生事件的配置文件设置更改为true
也放弃丑陋，脆弱，不可能读取xpath。 Watir具有更易读，更脆弱的方法来识别您想要点击的div。
开始一个新问题，包括该div存在的表格的一些HTML，以及如何选择它的逻辑（当然它与表格的内容有关？不仅仅是第二行的第二个单元格第三个表格）我们可以给你一些关于如何更好地选择元素的建议，这些元素将导致代码有意义且可读，如果表内容稍有变化则不会破坏，并且不会在最轻微的情况下中断页面设计。
