Use pytest with pytest-playwright against the staging site, following the page object model pattern with fixtures from conftest.py. The clean_session fixture logs in a test user, clears prior bookings, and yields ready-to-use page objects.

Each user can have at most 6 user-created events and 9 bookings. When the limit is reached, the oldest item is automatically deleted via FIFO replacement, and static seeded events do not count toward the event limit.

The booking reference follows the pattern [FIRST_LETTER]-[6_RANDOM_ALPHANUMERIC], where the first letter comes from the event title in uppercase. For example, booking 'Tech Summit' produces a reference like T-A3B2C1, with collision retry ensuring uniqueness.

Invalid login returns 401, duplicate email registration returns 409, cross-user booking access returns 403, and insufficient seats or past event dates return 400. Editing static seeded events also returns 403.

Key selectors include getByTestId('event-card') for event cards, getByTestId('book-now-btn') for booking links, #customer-email for the email field, and .confirm-booking-btn for submission. The full selector map covers login, events, booking, and admin pages.
