Session Storage Service

Name: tessl/pypi-pytest-redis
Author: tessl

Build a simple session storage service that uses Redis to store and retrieve user session data.

Requirements

Implement a SessionStore class that manages user sessions in Redis. The class should:

Accept a Redis client in its constructor
Store session data as JSON strings with user IDs as keys
Provide methods to create, retrieve, delete, and check session existence

Test Cases

Write tests using pytest fixtures to verify the SessionStore class behavior:

Storing a session with user ID "user123" and data {"name": "Alice", "role": "admin"} and then retrieving it returns the same data @test
Retrieving a non-existent session for user ID "user999" returns None @test
After deleting a session for user ID "user123", retrieving it returns None @test
After creating a session for user ID "user123", checking its existence returns True @test
