Api Platform Tests (Symfony)

Use when

• Designing or evolving API Platform contracts and operations.

• Aligning serialization, validation, and security behavior.

Default workflow

• Define operation-level contract and payload boundaries.

• Implement resource/DTO/provider/processor changes with explicit mapping.

• Apply operation-specific validation and security constraints.

• Validate functional behavior across happy and negative paths.

Guardrails

• Keep API contract explicit and version-aware.

• Avoid exposing internal entity fields implicitly.

• Prevent drift between docs and actual serialization.

Progressive disclosure

• Use this file for execution posture and risk controls.

• Open references when deep implementation details are needed.

Output contract

• API artifacts changed (resource/DTO/provider/processor).

• Contract/security decisions and rationale.

• Functional verification results.
