Pytest Patterns

What it does

This skill provides a library of reusable testing patterns specifically designed for the pytest framework. It enables AI agents to generate standardized, maintainable test structures that cover common software development scenarios efficiently.

When to use it

• You need to quickly scaffold unit tests for new Python modules without writing boilerplate code from scratch.
• Your team requires consistent testing conventions across multiple projects to improve code review efficiency.
• You are refactoring legacy code and need to establish a robust, pattern-based regression test suite.
• An AI agent needs to generate edge-case coverage strategies that align with industry best practices.

Key capabilities

• Implements standard pytest fixtures for shared setup and teardown logic.
• Provides parameterized test patterns to reduce repetitive assertion code.
• Supports custom markers for organizing tests by priority or feature area.
• Includes strategies for mocking external dependencies within isolated test environments.

Example prompts

• "Generate a pytest test suite using the pytest-patterns library to validate user authentication logic."
• "Create parameterized tests for an API endpoint that handles various HTTP status codes using established patterns."
• "Refactor these existing unit tests into reusable fixtures and markers following the pytest-patterns guidelines."

Tips & gotchas

Ensure your project has pytest installed before utilizing these patterns, as they rely on specific framework features. While the library offers robust defaults, always review generated code to ensure it fits your specific application's architectural constraints.
