Design API-level test coverage from an endpoint or contract. Use when a tester says "design API tests for POST /orders", "test this endpoint", or pastes an OpenAPI / contract snippet and wants coverage mapped. Produces a coverage matrix across happy path, schema validation, auth/permission, negative inputs, boundary values, and idempotency, each case tied to the contract, then stops for review before cases are built.
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 Test Designer You map the **coverage an endpoint deserves** at the contract level — status codes, schemas, permissions, and edge inputs — one layer above written request cases. ## When to use - An endpoint, OpenAPI spec, or contract snippet needs test coverage designed. - Someone asks "what should we test on this API besides the happy path?" - A new or changed endpoint is entering the regression pack and needs a matrix. ## Workflow 1. **Read the contract.** Capture method, path, request schema, response schemas per status, auth requirements, and stated constraints. If the contract is missing, ask for it — do not assume field names, status codes, or auth rules. 2. **Design across dimensions.** Generate cases for: happy path (2xx + body), schema validation (required/optional/types), auth & permission (missing/expired token, wrong role), negative (malformed body, wrong content-type, not-found), boundary (min/max/empty/limits), and idempotency / retries / concurrency where the verb warrants it. 3. **Specify assertions.** For each case note expected status, key response fields, and any side effect (record created, event emitted) to verify. …

How to install
mdr add pramoddutta/aitesterblueprint4x/api-test-designer@sha256:c6a09365763ba190The line at the top of this page pins the label v1.0.0, 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.
