1) Initialize the browser object

When initializing the driver object, selenium4 has an additional Service class to manage the start and stop of the driver.

service =

Service(r"E:\python39\chromedriver.exe")
driver = webdriver.Chrome(service=service)

2) Element positioning strategy

Selenium4 added relative positioning strategy

3) Find element method

Selenium4 is simplified, only the two methods of find_element and find_elements are retained.
In selenium3, in addition to the above two, there are find_element_by_XXX, find_elements_by_XXXX.

In fact, in the code of selenium3, the methods of find_element/elements_by_XXX are directly called find_elment and find_elements methods.

4) expected_condition module

In the expected_condition module of explicit waiting, selenium4 implements each condition in the form of a function.

In selenium 3, each condition is implemented through a class. There are 2 magic functions in the class, one is __init__, the other is __call__, of course, some other conditional methods have been added.

5) ActionChains class

-- Both selenium4 and appium2 use the ActionChains class to complete mouse operations, touch screen operations, and multi-touch operations.

In appium1, the touch screen operation TouchAction and MultiAction are implemented, and in appium2, the ActionChains class is changed to complete.

The implementation of ActionChains has also changed, please refer to the related article: Freshly released: appium2.0+ single-touch and multi-touch new solutions.
