Pytest Patterns
Pytest Patterns teaches structured testing for Python backends using pytest, httpx, and factory_boy. Learn to organize tests across unit and integration layers, build reusable fixtures with proper scoping, seed test data with factories, and test async FastAPI endpoints. Covers mocking, parametrization, and conftest hierarchy—but skips frontend and E2E testing.
Pytest Patterns provides testing patterns and best practices for FastAPI applications using pytest and related tools.

Frequently asked questions
AI-generated answers based on this skill's SKILL.md and metadata
What pytest testing patterns does Pytest Patterns cover?
Pytest Patterns teaches structured testing for Python backends using pytest, httpx, and factory_boy. The skill covers organizing tests across unit and integration layers, building reusable fixtures with proper scoping, seeding test data with factories, and testing async FastAPI endpoints. You'll learn mocking, parametrization, and conftest hierarchy to write maintainable, scalable test suites.
How to write pytest tests with best practices?
Pytest Patterns demonstrates how to write pytest tests by teaching test organization, fixture design with correct scoping, and reusable test patterns. The skill emphasizes structuring tests across unit and integration layers, using factory_boy for test data seeding, and leveraging conftest hierarchy. You'll learn assertion patterns, error handling tests, and parametrization techniques to build robust, maintainable test code.
What pytest code examples and reusable patterns are included?
Pytest Patterns provides code examples covering fixtures, mocking patterns, parametrization, and assertion strategies. The skill includes reusable test patterns for unit and integration testing, async FastAPI endpoint testing with httpx, and factory_boy data seeding. Examples demonstrate proper fixture scoping, conftest organization, and common testing scenarios to help you apply patterns directly to your Python backend projects.
How does Pytest Patterns help structure and organize tests?
Pytest Patterns teaches test organization across unit and integration layers, conftest hierarchy for fixture management, and proper fixture scoping. The skill covers structuring test suites for Python backends, organizing reusable fixtures, and using factory_boy for consistent test data. You'll learn how to build scalable test architectures that separate concerns and make tests easier to maintain and extend.
What advanced pytest techniques and fixtures does this skill cover?
Pytest Patterns covers advanced techniques including fixture scoping strategies, mocking patterns, parametrization for data-driven tests, and conftest hierarchy. The skill teaches testing async FastAPI endpoints with httpx, error handling test patterns, and integration testing approaches. You'll discover how to build sophisticated, reusable fixtures and apply advanced pytest features to complex Python backend testing scenarios.
Does Pytest Patterns include frontend or E2E testing?
Pytest Patterns focuses exclusively on structured testing for Python backends and does not cover frontend or end-to-end (E2E) testing. The skill concentrates on pytest, httpx, and factory_boy for unit and integration testing of backend services, particularly async FastAPI applications. For frontend or E2E testing, you would need separate resources outside this skill.
