Interview: what are the positioning methods in selenium? Which one do you use most?

Hello, everyone , I'm Daejeon .

 

Selenium There are eight positioning methods in ：id、name、class_name、tag_name、link_text、partitial_link_text、XPath、CSS.

 

There are three kinds of commonly used ：

The first is id：  There is id, Use id It is easy to locate , The positioning speed is the fastest ;

The second is XPath： Most of the time, the label attributes of the front end are not standardized , The element cannot be uniquely determined , Use XPath Relative position positioning ;

The third is CSS positioner , Locating in the browser is faster than XPath fast .

 

It should be noted that ： When positioning elements , Try to choose stable 、 Element attributes that are not easy to change , stay XPath Use indexes as little as possible in , To some extent, it can reduce the maintenance of automated test scripts .
