Feature: Upload and process a book picture

The service receives a picture file for a book, which is processed and stored in the database.
The system validates whether the book exists before adding or updating the picture.

Scenario: Upload picture for an existing book

Given a valid picture file for an existing book is sent to the upload endpoint
When the picture file is uploaded to the service
Then the service should extract metadata to identify the book
And check if the book exists in the database
And if the book exists, the service updates the book's picture with the new file

Scenario: Upload picture for a new book

Given a valid picture file for a new book is sent to the upload endpoint
When the picture file is uploaded to the service
Then the service should extract metadata to identify the book
And if the book does not exist in the database, it should be added
And the new picture should be associated with the new book in the database

Scenario: Upload picture for a non-existent book

Given a picture file for a non-existent or invalid book is sent to the upload endpoint
When the picture file is uploaded to the service
Then the service should return an error response indicating the book was not found in the system

Scenario: Upload invalid or corrupted picture file

Given an invalid or corrupted picture file is sent to the upload endpoint
When the file is uploaded to the service
Then the service should return an error response indicating the picture file could not be processed
