In what situations and tasks do you choose to use Selenium for automation testing?

Selenium is chosen for automating web application testing when:

• Checking the functionality of the user interface in browsers
• Automating regression testing of websites
• Testing cross-browser compatibility and interaction with page elements

Selenium is well-suited if the application has a complex UI and requires emulation of user actions (clicks, text input, navigation). It supports various programming languages and browsers.

Example of using Selenium in Python to open a page and check the title:

from selenium import webdriver

browser = webdriver.Chrome()
browser.get('https://example.com')
assert 'Example Domain' in browser.title
browser.quit()
