api-testing SKILL.md skillA
api-testing from event4u-app/agent-config is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add event4u-app/agent-config/api-testing@git:20261002.a3c8393Pins git:20261002.a3c8393 in mdr.lock. Pin the fingerprint instead.

Use when writing API endpoint tests — integration tests, contract validation, response assertions, mocked external services — even when the user says 'test this route' without naming API testing.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# api-testing
## When to use
Use this skill when writing or reviewing API endpoint tests — integration tests,
contract validation, response structure checks, or external service mocking.
## Procedure: Write API tests
1. **Understand the endpoint** — Read the controller, form request, and existing tests. Understand expected behavior, edge cases, and auth requirements before writing anything.
2. **Set up test data** — Use seeders (preferred) or factories. Mock external services with `Http::fake()`.
3. **Enumerate test cases** — Run the [`test-case-discovery`](../test-case-discovery/SKILL.md) funnel first; cover success, validation errors, authorization failures, and edge cases — floor per behavior: 1 happy + 1 boundary + 1 error (+1 abuse case; on data-returning endpoints the three `broken-access-control` negative tests are mandatory).
4. **Assert response** — Check status code, JSON structure, data values. Use `assertJsonStructure()`.
5. **Verify** — Run the test. Must pass. Check no flaky assertions (no time-dependent, no random ordering).
### Example
```php
describe('GET /api/v1/projects', function () {

How to install
mdr add event4u-app/agent-config/api-testing@sha256:21456e909ee1628bThe line at the top of this page pins the label git:20261002.a3c8393, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
