A browser developer mode

Firefox-->firebug front-end tools, and for Chrome browser-right-click ' Review elements ' or ' F12 ', you can see some code developed for writing, which is useful for getting some properties of test objects (test controls).

b Browser Basic operation

Maximize browser window and size settings, as well as forward, rewind
Here are a few notes:
Xxxx.get (URL) go to URL address
Time.sleep (NS) Wait time
Xxxx.back () return to previous browser
Xxxx.forward () forward to the next browser
Xxxx.set_window_size (width,height) Width,height we can set ourselves as needed.
Xxxx.maximize () window maximization
Xxxx.title get the title of the browser
Xxxx.quit () Browser exit
Xxxx.close () Browser off

Import time-> to ensure the stability of script operation
Browser=webdriver. Chrome (), calling Chrome browser
Use the print () statement to see if the script is running correctly
