Architecture Overview: The Testing Pyramid in Action

Our testing setup follows a strategic pyramid approach:

Unit Tests (Foundation): Fast, isolated tests using pytest fixtures that verify individual components work correctly. These run in milliseconds and catch logic errors early.

Integration Tests (Middle): Tests that verify your application works with real databases and external services. We'll use test-specific PostgreSQL databases and Redis instances to ensure data integrity.

End-to-End Tests (Peak): Full workflow tests using React Testing Library that simulate real user interactions from frontend to backend.
