# Python Testing Patterns

Write Python tests you will trust when they fail

## What this does

You need tests for Python code and are not sure how to structure them, or an existing suite has become hard to work in. This covers writing tests with pytest, sharing setup, standing in for things you cannot really call, and letting tests lead the code. Reach for it when starting a suite or straightening one out.

### Top 3 things it does for you

- Set up a test suite from scratch
- Write fixtures that cut the repetition
- Mock out the parts you cannot call for real

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Python Testing Patterns

A test suite is easy to start and easy to make unpleasant. This skill covers testing strategies with pytest, fixtures, mocking, and test-driven development.

Use it when writing Python tests, setting up a test suite, or working out the testing practices a project should follow.

## Questions

### Is Python Testing Patterns safe to install?

AIR scanned this exact version of Python Testing Patterns and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit be57c0b2e3c0, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/python-testing-patterns.

### How do I install Python Testing Patterns?

Open https://airmarket.ai/app/python-testing-patterns on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/wshobson/agents/tree/be57c0b2e3c05c528ca6132b87410b385718775f/plugins/python-development/skills/python-testing-patterns. Install from that link, not the branch.
