pytest

What problem does it solve?

Pytest provides a structured framework for Python testing, enabling reusable fixtures, powerful mocking patterns, and expressive test declarations to improve reliability and maintainability.

Core Features & Use Cases

• Fixtures: reuse setup code across tests for consistent environments.
• Parameterization and Markers: run multiple inputs and categorize tests for faster feedback.
• Mocking and assertions: simulate complex interactions and verify behavior without external dependencies.
• Use Case: large Python project with many modules can leverage pytest to standardize test structure and reporting.

Quick Start

Run pytest in your Python project to execute tests and start leveraging fixtures, mocks, and parameterization.
