Selenium Webdriver高亮元素，然后单击 [英] Selenium webdriver highlight element before clicking
问题描述
我正在研究一组用Python编写的硒UI测试.在以前的项目中，我使用的是WatiN和C#.
I'm working on a set of selenium UI tests that are written in Python. On a previous project I was using WatiN and C#.
您可以启用WatiN框架的功能，以突出显示"您单击，选择或键入的元素.在执行操作时，该元素周围会出现黄色边框.我发现这在对损坏的测试进行故障排除时非常有用，通常可以从测试运行中查看是否单击了错误的元素.
The WatiN framework had a feature you could enable that would 'highlight' the element you were clicking, selecting or typing into. The element would get a yellow border around it while the action was performed. I found this extremely helpful while troubleshooting broken tests, I could often see from the test run if the wrong element was being clicked.
我想知道Selenium Webdriver是否具有可以打开的类似功能.基本上，我想以某种视觉方式指示正在与哪些元素进行交互.
I was wondering if Selenium webdriver has a similar feature that I can turn on. Basically I would like some sort of visual indication of what element is being interacted with.
谢谢！
推荐答案
Selenium RC可以做到这一点，但是WebDriver中没有直接的API方法可以做到这一点.您的选择是:
Selenium RC could do this but there is no direct API method to do this in WebDriver. Your options are:
1)在您的语言绑定中使用WebDriverBackedSelenium实现来访问Highlight方法.
1) Use the WebDriverBackedSelenium implementation in your language bindings to access the Highlight method.
2)只需使用JavascriptExecutor(或您的语言绑定中的类似实现)调用一些javascript，即可为您完成工作.这将模仿 Selenium RC/option 1 (硒RC/选项1)将实现的效果.
2) Simply call some javascript using the JavascriptExecutor (or similar implementation in your language bindings) to do the job for you. This will mimic what Selenium RC/option 1 would achieve.
要调用的Javascript存在于此处:
The Javascript to call exists here:
http://code. google.com/p/selenium/source/browse/javascript/selenium-core/scripts/htmlutils.js
要注意的功能是highlight功能.只需使用JavascriptExecutor加载此脚本(搜索以使用您的编程语言进行搜索即可).
The function to note is the highlight function. Just load this script using the JavascriptExecutor (search to find out how to do this in your programming language).
然后可以对此进行比较，以查看Java API中的WebDriverBackedSelenium实现如何使用它:
You can then compare this to see how the WebDriverBackedSelenium implementation in the Java API's are using it:
Use this, to do this same in your own code.
作为旁注，用于Firefox的Selenium IDE也可以突出显示方法.
As a side note, the Selenium IDE for Firefox can highlight methods as well.
