Are you familiar with the Page Object Model pattern?

Yes, the Page Object Model (POM) pattern is widely used in UI test automation. Its essence is to create an abstraction for each page or component of the application in the form of a separate class or object.

This allows:

• Centralized storage of element locators and interaction methods.
• Improved readability and maintainability of tests.
• Avoidance of code duplication.

Example in Python with Selenium:

class LoginPage:
    def __init__(self, driver):
        self.driver = driver
        self.username_input = driver.find_element(By.ID, 'username')
        self.password_input = driver.find_element(By.ID, 'password')
        self.login_button = driver.find_element(By.ID, 'login')

    def login(self, username, password):
        self.username_input.send_keys(username)
        self.password_input.send_keys(password)
        self.login_button.click()

Tests use this class to interact with the login form without worrying about locator details.
