WebDriver API——第1部分

The API definitions in this chapter shows the absolute location of classes. However the recommended import style is as given below:

from selenium import webdriver

Then, you can access the classes like this:

webdriver.Firefox
webdriver.FirefoxProfile
webdriver.Chrome
webdriver.ChromeOptions
webdriver.Ie
webdriver.Opera
webdriver.PhantomJS
webdriver.Remote
webdriver.DesiredCapabilities
webdriver.ActionChains
webdriver.TouchActions
webdriver.Proxy

The special keys class (Keys) can be imported like this:

from selenium.webdriver.common.keys import Keys

The exception classes can be imported like this (Replace the TheNameOfTheExceptionClass with actual class name given below):

from selenium.common.exceptions import [TheNameOfTheExceptionClass]

Conventions used in the API

Some attributes are callable (or methods) and others are non-callable (properties). All the callable attributes are ending with round brackets.

Here is an example for property:

• current_url

  URL of the current loaded page.

  Usage:

  driver.current_url
  

Here is an example for a method:

• close()

  Closes the current window.

  Usage:

  driver.close()
