SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pytest, pytest-cov, pytest-mock, pytest-asyncio, hypothesis, faker, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill streamlines the process of creating robust and reliable tests for Python applications, ensuring code quality and maintainability.

Core Features & Use Cases

  • Comprehensive Testing: Implement unit, integration, and end-to-end tests.
  • Pytest Configuration: Set up pytest, fixtures, mocking, and coverage reporting.
  • TDD & Property-Based Testing: Adopt Test-Driven Development and advanced techniques like Hypothesis for thorough validation.
  • Use Case: You need to ensure your new API endpoint is thoroughly tested before deployment. This Skill will guide you in setting up pytest, writing tests for various scenarios (success, failure, edge cases), and configuring coverage to guarantee all code paths are exercised.

Quick Start

Create a basic unit test for the add function in src/calculator.py using pytest.
