Python Selenium Series (iii) common operation types and methods

a preface

The core idea of Web UI Automation is to find elements, and then manipulate the two elements. In the Python Selenium series (ii) Element positioning method article, which describes how to find an element, this article describes the second item, how to manipulate the elements that have already been found.

Classification of two operation methods

Overall, the operation can be broadly divided into four categories, namely browser operation, keyboard operation, mouse operation, JS script .

1. How to use the browser:

Method	Describe
Driver.maximize_window ()	window maximized
driver.back ()	page return
Driver.forward ()	Page forward

2. Keyboard Common operation method:

Send_keys () # keys analog Keyboard input, analog keyboard keys, key combinations, etc.

some of the keys are listed below:

alt= u ' \ue00a '

arrow_down= u ' \ue015 '

arrow_left= u ' \ue012 '

arrow_right= u ' \ue014 '

arrow_up= u ' \ue013 '

backspace= u ' \ue003 '

back_space= u ' \ue003 '

cancel= u ' \ue001 '

clear= u ' \ue005 '

command= u ' \ue03d '

control= u ' \ue009 '

3. Mouse Common operation method:

Click () # Actionchains Analog mouse operation, in addition to the most commonly used click, there are right click, double-click, etc.

Method	Describe
Click (on_element=none)	Click left mouse button
click_and_hold (on_element=none)	Click left mouse button, do not release
Context_click (on_element=none)	right mouse button
Double_click (on_element=none)	Double-click the left mouse button
Drag_and_drop (source,   target)	Drag to an element and release
Drag_and_drop_by_offset (source,xoffset,yoffset)	Drag to a coordinate and release
Key_down (value,   element=none)	Press the key on one of the keyboards
key_up (value,   element=none)	release a key
Move_by_offset (xoffset,   yoffset)	mouse moved from current position to a coordinate
move_to_element (to_element)	mouse moves to an element
Move_to_element_with_offset (to_element,   Xoffset, Yoffset)	move to the position of how far away from an element (upper-left corner coordinates)
perform ()	All actions in the execution chain
release (on_element=none)	release the left mouse button at an element location
Send_keys (*keys_to_send)	send a key to the current focus element
Send_keys_to_element (element, *keys_to_send)	Sends a key to the specified element

4. Call the JS script:

Execute_script   # Execute JS script to complete specific actions

three operation Practical Example

1. Browser Operation Example

2. Keyboard Operation Example

3. Mouse Operation Example

4. Script action Example

four Additional knowledge points supplement

actionchains (browser). Double_click (Click_button). Perform () # Mouse Double-click Operation Example

in the mouse operation, notice that the Actionchains (Driver). Whenthe method is called, the action is not executed immediately, but all operations are stored sequentially in a queue, and when the Perform () method is called , the time in the queue executes sequentially. So when you use the mouse, you need to call the Perform () method to complete the execution of the action.
