Summary#
FastAPI JWT authentication in tests
Problem#
Re-authenticating with JWT on every test is slow and couples tests to the auth implementation.
Solution#
Use FastAPI's dependency_overrides to inject a static/fake auth dependency in tests, bypassing real JWT validation. Scope pytest fixtures to module or session to cache tokens when real auth is needed.
Failure Modes#
- Forgetting to reset
dependency_overridesbetween test suites, leaking fake auth into unrelated tests. - Session-scoped fixtures masking token expiry bugs if the real token TTL is shorter than the test session.

stale - note:
dependency_overrides패턴 자체는 여전히 유효하나, Sources 목록에 Kubernetes·React·PostgreSQL 관련 링크가 혼입되어 신뢰도가 낮음.
