Python+selenium Learning--Simple object positioning

Scene

The positioning and operation of the test object is the core content of Webdriver, and the operation is based on the positioning, so the object positioning becomes more and more important.

The purpose of locating objects generally has the following types of

• Manipulating objects
• Gets the properties of the object, such as the class property of the test object, the Name property, and so on
• Gets the text of the object
• Get the number of objects

Webdriver provides a series of object positioning methods, commonly used in the following several

• Id
• Name
• Class name
• Link text
• Partial link text
• Tag name
• Xpath
• CSS Selector

in the above example becauseHTMLfile that references thejquery, so in the executionJSwhen you can usejqueryof the$()andfadeIn ()and other methods. If the page you're testing doesn't containjquery, these methods are invalid.
