# Api Platform Tests (Symfony)

## Use when
- Writing functional tests for API Platform endpoints: collection, item, create, update, delete.
- Asserting validation errors (422) and access control (401, 403).
- Checking filters, pagination, or the JSON schema of responses.
- Setting up a clean database and test data for API tests.

## Default workflow
1. Extend `ApiTestCase` and seed data with Foundry factories (`createOne`, `createMany`).
2. Reset state with `#[ResetDatabase]` and the `Factories` trait, with DAMA rolling back each test.
3. Call `static::createClient()->request()` and assert the status code, content type, and `assertJsonContains()`.
4. Authenticate with `auth_bearer` and cover the anonymous, owner, and other-user cases.
5. Assert `member` and `totalItems` for filters and pagination (`hydra:`-prefixed only with `hydra_prefix: true`).
6. Assert the shape with `assertMatchesResourceItemJsonSchema()` and `assertMatchesResourceCollectionJsonSchema()`.

## Guardrails
- Send `PATCH` with the `application/merge-patch+json` content type.
- `#[ResetDatabase]` needs PHPUnit 10+ and Foundry 2.9: use the `ResetDatabase` trait on PHPUnit 9.
- Cover the failure paths too: 404, 422, 401, 403. A type error on a constrained property is 422 in 5.0 but 400 in 4.4 and earlier.
- Read the configured items per page rather than hardcoding a page size in assertions.

## Progressive disclosure
- Use this file for execution posture and risk controls.
- Open references when deep implementation details are needed.

## Output contract
- The test classes added and the endpoints they cover.
- Factories and reset strategy used.
- Test run output, including the failure paths.
