How does this skill handle external API or database dependencies?

It provides standardized implementation patterns for mocking, patching, and monkeypatching to ensure tests run in isolation without side effects.

What testing frameworks does this skill support?

It primarily focuses on pytest, the industry-standard framework for Python, while also utilizing built-in libraries like unittest.mock for isolation.

Does it support Test-Driven Development (TDD)?

Absolutely. The skill is designed to facilitate TDD workflows by providing clear structures for writing failing tests before implementation code.

Can it help with testing asynchronous Python code?

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

Can it help with setting up test data?

Yes, it features patterns for creating reusable pytest fixtures that handle the 'Arrange' and 'Teardown' phases of testing efficiently.
