Test cases are written in app/tests.py files for all the methods Post(create), Get(read), Put(update), Delete(delete)

If one wants to remove an item from the invoice, the quantity should be set zero for that item and it will automatically get deleted.

New item can also be added in the update request those will also be added corresponding to the 'pk' for the invoice, however the description field is mandatory while adding a new item with update(Put) method.

This is one json format format for testing the APIs manully {
