Watir-webdriver在詢問元素是否存在時超時？

紅寶石1.9.3p327
的Watir-的webdriver 0.6.1

在新的Ruby安裝，用新鮮的webdriver的安裝，我無法使用等待或禮物？與不存在的元素不會導致非Watir超時錯誤。Watir-webdriver在詢問元素是否存在時超時？

在下面的例子中，ID「gb_32」是網頁，而是隱藏在。 Id'gb_50000'不存在。在這兩種情況下「存在」？應該返回false，但第二個在60秒後給我一個超時錯誤。任何想法爲什麼會發生這種情況？

irb(main):014:0> b.link(:id,'gb_32').present? 
    => false 
    irb(main):015:0> b.link(:id,'gb_50000').present?

我現在通過在「現在？」中使用顯式超時設法組裝了一個kludge。和「直到」方法。像這樣： 'Timeout :: timeout（input_timeout = 1）do; ＃默認webdriver命令在這裏; 結束; 救援超時::錯誤; raise TimeoutError; 結束' – Virtuoso

你能分享鏈接到頁面或相關的HTML嗎？ –

我認爲這取決於網絡驅動程序。我在看的頁面是「www.google.com」。當我嘗試尋找存在時，故障仍然出現在「about：blank」上？或存在？對於不存在的元素。 – Virtuoso

我會將此添加爲評論，但顯然我還不能。你使用Firefox 17嗎？ Watir-webdriver尚未與17兼容，因此如果您嘗試恢復到Firefox 16並查看您的代碼是否正常工作。我瞭解到，解決此兼容性問題的watir-webdriver更新將於下週發佈。

感謝您的回覆。我已經完全重新安裝了Windows，似乎已經解決了這個問題。我相信這是筆記本電腦以前用戶的某種間諜軟件/惡意軟件的副作用。 – Virtuoso

是的，那個特定的錯誤文本，並沒有說什麼，當它超時它試圖做什麼（就像等待一個元素），似乎是webdriver本身試圖與瀏覽器交談時的超時指示..問題是回到那裏。不是在你的代碼或網頁上..這是webdriver和瀏覽器之間的通信正在超時 –
