• Test edge cases, such as:
  • Trying to book a full class
  • Attempting to create more than 5 schedules per day
  • Booking conflicting time slots
  • Accessing routes without proper authorization

For a more comprehensive testing experience, consider using API testing tools like Postman or Insomnia. These tools allow you to save and organize your API requests, making it easier to test your application thoroughly.
