注册:安全证书上的WebDriver

Question

我在过去的6个月里一直在使用WebDriver。

我现在面临着几个问题，版本2.3.1

a)当我尝试通过webdriver findElement在IE的安全证书https页面上获取覆盖链接的元素时，它无法找到该元素，但selenium RC工作正常。

然后，我通过使用以下命令获得了tht的修复: webDriver.navigate().to(javascript:document.getElementById('overridelink').click())；

注意:我尝试使用下面的代码来获取安全证书页面上的元素，但是它返回了body元素

带有焦点的WebElement activeElement() WebElement，或者如果没有检测到带有焦点的元素，则为正文元素。为什么不能使用findelement来挑选元素？

b)我通过SSL连接远程网络以运行webdriver测试，无法单击安全证书https页面上的override链接？

c)实现webdriver的更好的方法是直接使用它而不是使用jbehave这样的框架吗？

请提供您的建议谢谢，Jayaraj A

Answer 1

感谢您的变通！

对于Java，您的解决方案看起来有点不同，这对我很有帮助：

//driver is initialised somewhere before, for example, as RemoteWebDriver     
driver.navigate().to("javascript:document.getElementById('overridelink').click()");

Answer 2

是啊，我也有过类似的问题。Webdriver似乎没有完整的信息

由于某种原因导致的证书错误页面。

我在Windows XP SP3上，使用Python/Webdriver运行IE7

我正在使用这个黑客来绕过证书错误页面：

(帮助，我仍然不能获得自由的Markdown来格式化代码块...)
