Why use AsyncClient instead of TestClient?

AsyncClient provides native async support and avoids the sync-to-async bridge overhead, resulting in approximately 20% faster test execution.

How does this skill handle database isolation?

It implements a transaction rollback pattern in conftest.py, which allows tests to run in isolation without the massive overhead of recreating the database schema for every test.

Does it support the latest versions of FastAPI and Pytest?

Yes, this skill is specifically optimized for FastAPI v0.100+ and Pytest v8.0+, ensuring compatibility with modern async features and Pydantic v2.

Can I run tests in parallel with this setup?

Absolutely. The skill includes configuration blueprints for pytest-xdist to enable efficient parallel execution of your test suite.

安全与测试

Streamlines Test-Driven Development for FastAPI projects using high-performance Pytest patterns and async fixtures.

关于

This skill acts as a Senior Backend Architect and Principal QA Engineer to facilitate high-performance testing in FastAPI applications. It prioritizes execution speed and memory efficiency by implementing the Red-Green-Refactor TDD cycle, transaction-based test isolation for faster runs, and native async testing with httpx.AsyncClient. It is ideal for developers looking to set up robust test suites with async database sessions, Pydantic response validation, and optimized parallel execution patterns.
