Can you describe how you would automate an authorization scenario in a mobile app? Test cases, structure, Page Object?

To automate the login scenario in a mobile application, the following approach can be used:

1. Test Cases:

   • Successful login with valid data.
   • Login attempt with incorrect password.
   • Login attempt with a non-existent user.
   • Check mandatory fields (e.g., empty username or password).
   • Check behavior when the network is lost.

2. Structure:

   • Use an automation framework (e.g., Appium).
   • Divide tests by functional blocks.
   • Use setup/teardown for preparing and cleaning up the state.

3. Page Object:

   • Create a class/object LoginPage that encapsulates elements and actions on the login page.

Example in Python using Page Object:

class LoginPage:
    def __init__(self, driver):
        self.driver = driver
        self.username_field = driver.find_element_by_id('username')
        self.password_field = driver.find_element_by_id('password')
        self.login_button = driver.find_element_by_id('login')

    def login(self, username, password):
        self.username_field.send_keys(username)
        self.password_field.send_keys(password)
        self.login_button.click()

# In the test
login_page = LoginPage(driver)
login_page.login('user', 'pass')
# Check for successful login

This approach makes it easier to maintain tests and makes them more readable and scalable.
