• insertBookingRandom.py: This script is likely used to insert random booking data into a database or a system. It could be used for testing the functionality of a booking system by populating it with sample data to ensure that bookings are being recorded and processed correctly.
• test.py: This script is typically used to run a series of unit tests on your application. It might include a suite of tests that validate the correctness of your application's logic, functions, and classes to ensure that recent changes haven't broken existing functionality.
