# Test + lint tooling — NEVER in the prod image. Installed only by backend/Dockerfile.test (the # throwaway test image), which the prod build (root Dockerfile) never references. Pinned so the # suite is reproducible: pytest for the pure-logic tests, and ruff at the SAME version the gate's # backend lint lane runs on the host (the gate fails when the host's ruff is not this one). httpx2: # Starlette 1.x's TestClient is built on it (`import httpx2 as httpx`) and only falls back to the # app's own httpx with a deprecation warning on every run. pytest==8.4.2 ruff==0.15.21 httpx2==2.13.0
