Trigger: User opens the Prediction Polls app and selects the login/registration page.

Scenario:

    1. The app displays the registration form.
    2. The user fills out the registration form, including name, email address, and password.
    3. The user submits the registration form.
    4. The app verifies the email address is not already registered.
    5. If the email address is not already registered, the app creates a new account for the user and logs them in automatically.

    2. The user selects the "Login" button.
