Can I use this for mocking external REST APIs?

Absolutely. The skill provides detailed patterns for using unittest.mock to simulate API responses, patch requests, and handle HTTP error states.

Does this skill support testing asynchronous Python code?

Yes, it includes specific patterns for testing async functions and concurrent operations using pytest-asyncio and async fixtures.

Is this skill compatible with existing pytest setups?

Yes, it follows standard pytest conventions and industry best practices, making it ideal for enhancing or refactoring existing project test suites.

How does it help with Test-Driven Development (TDD)?

It provides structured boilerplate and logic for writing tests before code, focusing on the Arrange-Act-Assert structure to validate requirements from the start.

Security & Testing

Implements comprehensive testing strategies using pytest, fixtures, and mocking to ensure robust Python code quality.

About

This skill provides a technical foundation for Python developers to implement professional-grade testing suites. It covers essential patterns including the Arrange-Act-Assert (AAA) structure, pytest fixtures for efficient setup/teardown, parameterization for high edge-case coverage, and complex mocking scenarios using unittest.mock. Whether you are building unit tests for isolated functions or integration tests for asynchronous APIs, this skill ensures your test infrastructure is maintainable, isolated, and scalable within any Python-based project.
