Browser a developer Mode

FireFox --> Firebug front-end tool, and for Chrome browser --> right-click 'review element' or the shortcut key F12, you can see some code written by the developer, which gets the test object (Test Control) some attributes.

Basic operations of browser B

Maximize and set the size of the browser window, and move forward and backward
Note the following points:
XXXX. get (URL) to URL
Time. sleep (ns) wait time
XXXX. back () returns to the previous Browser
XXXX. forward () move forward to the next Browser
XXXX. set_window_size (width, height) width and height can be set as needed.
XXXX. maximize () window Maximization
XXXX. title to get the browser title
XXXX. quit () browser exited
XXXX. close () close the browser

Import time-> ensure the stability of script operation
Browser = webdriver. Chrome ()-> call the Chrome browser
Use the print () statement to check whether the script runs correctly.
