pytest - Professional Python Testing

What problem does it solve?

This Skill provides a comprehensive guide to pytest, the industry-standard Python testing framework, enabling developers to write robust, efficient, and maintainable tests for their Python applications.

Core Features & Use Cases

• Fixture System: Manage test dependencies and setup/teardown logic.
• Parametrization: Run tests with multiple data sets efficiently.
• Markers: Organize and selectively run tests (e.g., unit, integration, smoke).
• Framework Integration: Seamlessly test FastAPI, Django, and Flask applications.
• Use Case: A developer needs to ensure their FastAPI endpoints are functioning correctly under various conditions. They can use pytest with fixtures and parametrization to test different request payloads and assert expected responses, including error handling.

Quick Start

Use the pytest skill to write a basic test function for a Python function named add that returns the sum of two numbers.
