推荐答案

在我看来，最准确的方法是XPath，你可以使用XPath来描述确切的位置

In my opinion, the most accurate way is XPath as you can use XPath's to describe the exact position of an element within the DOM, however there are some instances where CSS locators work better than XPaths.

使用selenium的ID定位器是最简单的，但除非你的元素

Using selenium's ID locator is the most simple, but unless the element you are looking for has an ID not always useful.

使用XPath时最大的负面影响是Selenium RC和带有不良JavaScript渲染引擎的浏览器的性能（Think IE6 / IE7）。相当多的工作已经穹顶，尝试和纠正这，所以如果你使用良好形成的XPath的，只搜索DOM的特定部分，这个问题应该是最小的。 Selenium webdriver的实现速度要快得多。

The biggest negative when using XPath's is the performance with Selenium RC and browsers with bad JavaScript rendering engines (Think IE6/IE7). Quite a bit of work has been dome to try and rectify this so if you use well formed XPath's that only search specific parts of the DOM this problem should be minimal. The Selenium webdriver implementation is much faster.

总结是没有一个答案，它取决于你想要的定位器，以及你正在测试哪些浏览器。我个人在99％的实例中使用XPath。

The summary is really there is no one answer it depends what you want out of a locator, and which browsers you are testing. I personally use XPath in 99% of instances.

我个人使用XPath几乎只使用偶尔的CSS定位器。

I personally use XPath almost exclusively with the occasional CSS locator.
