Test Cases

The candidate needs to implement the test cases as well. However, he/she can skip testing views, instead can only concentrate on main logic testing. For eg: Testing if the appointment is booked and not yet paid, the get_timeslots_for_day(day, duration) function should return the all the time slots if the time of 15 minutes has been passed, else all but the current timeslot.


The candidate needs to create the REST API using Django REST Framework to expose all the functions specified in the requirements.
