场景：需要找到Table中的某一行，然后找到这行的铅笔图标，点这个铅笔图标会出来下拉菜单，然后在下拉菜单中点击Open

刚开始写脚本的时候，按照以往的方式会报这样的错误："Element is not currently visible and so may not be interacted with"

这个元素在界面上是可见的，也通过正则表达式唯一匹配到了，可是在Click的时候就是不行。

后来查阅资料，发现这个元素的父元素是hidden的。

原文如下：

Selenium determines an element is visible or not by the following criteria (use a DOM inspector to determine what css applies to your element, make sure you look at computed style):

• visibility != hidden
• display != none (is also checked against every parent element)
• opacity != 0 (this is not checked for clicking an element)
• height and width are both > 0
• for an input, the attribute type != hidden

Your element is matching one of those criteria. If you do not have the ability to change the styling of the element, here is how you can forcefully do it by using Actions in the code.

后来我是这样解决的，可以成功运行了。

Actions action =new Actions(driver);
WebElement pencilIcon = page.getPencilIcon(templateName);
action.moveToElement(pencilIcon).click();

WebElement menu = page.getMenu();
action.moveToElement(menu).build().perform();
Assert.assertTrue(menu.isDisplayed(),"Cannot find the menu");

WebElement open = page.getOpenMenu();
open.click();
