Implement comprehensive testing strategies with pytest, fixtures, mocking, and test-driven development. Use when writing Python tests, setting up test suites, or implementing testing best practices.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Python Testing Patterns Comprehensive guide to implementing robust testing strategies in Python using pytest, fixtures, mocking, parameterization, and test-driven development practices. ## When to Use This Skill - Writing unit tests for Python code - Setting up test suites and test infrastructure - Implementing test-driven development (TDD) - Creating integration tests for APIs and services - Mocking external dependencies and services - Testing async code and concurrent operations - Setting up continuous testing in CI/CD - Implementing property-based testing - Testing database operations - Debugging failing tests ## Core Concepts ### 1. Test Types - **Unit Tests**: Test individual functions/classes in isolation - **Integration Tests**: Test interaction between components - **Functional Tests**: Test complete features end-to-end - **Performance Tests**: Measure speed and resource usage ### 2. Test Structure (AAA Pattern) - **Arrange**: Set up test data and preconditions - **Act**: Execute the code under test - **Assert**: Verify the results ### 3. Test Coverage - Measure what code is exercised by tests - Identify untested code paths …

How to install
mdr add hermeticormus/libreuiux-claude-code/python-testing-patterns@sha256:3b6b5b1d9fbd34ebThe line at the top of this page pins the label git:20251120.288a379, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
