嘗試使用watir-webdriver雙擊元素的Native Events錯誤

Question

我正在爲GWT應用程序寫入自動測試。我嘗試雙擊表格元素。我使用此代碼FO點擊：

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 

當執行此命令，我得到錯誤，如：

test_search(TC_article_example):Selenium::WebDriver::Error::InvalidElementStateError: Cannot perform native interaction: Could not load native events component.

我加入這個代碼給我的腳本，但是這並沒有幫助：

profile = Selenium::WebDriver::Firefox::Profile.new 
profile.native_events = false 
browser = Watir::Browser.new :firefox, :profile => profile 

請給我點建議。我用硒2.31,watir 4.0和firefox 19.0.2。 PS：對不起，我的英文不好。

這個錯誤聽起來像是想要本地事件，而你卻在禁止它們。嘗試將本機事件的配置文件設置更改爲true

也溝醜，脆，不可能讀取xpath。 Watir有更多的可讀性，不太脆弱的方法來識別您嘗試點擊的div。

開始一個新的問題，包括該div所在的表的HTML的一些HTML，你如何選擇它的邏輯（當然，它涉及表的內容？不僅僅是第二行的第二行第三個表體），我們可以給你一些建議，關於如何更好地選擇會導致代碼有意義並且可讀的代碼的元素，如果表內容稍微改變，則不會中斷，並且不會在最輕微的情況下中斷 - 設計的頁面。
