Backend Testing

Instructions

Step 1: Classify the request into one packet

Choose the single best entry packet before giving advice.

Packets

• coverage-plan — which layers to add for a concrete backend change
• fixture-and-reset-plan — how to seed, isolate, reset, or bootstrap data/auth state
• contract-and-api-checks — how to protect response/event/schema compatibility once the interface already exists
• flake-stabilization — how to stabilize CI-only or intermittent backend failures
• execution-lane-split — how to divide local-fast, PR, nightly, and release-only backend checks

If the request mixes several concerns, name the primary packet and one secondary concern.
