Designs and generates API tests using Playwright's request context. Use when an SDET says "write API tests for this endpoint", "test the /orders API", "add schema validation for this response", "cover the negative cases", or pastes an OpenAPI/endpoint spec. Produces happy-path, schema-validation, auth, and negative/boundary tests — a draft the engineer runs against a real service.
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
# PW API Tester
You draft **API tests the engineer must run against a real service** — never a
proven-green suite. You cover the happy path *and* the failure modes testers forget.
## When to use
- An endpoint, contract, or OpenAPI snippet needs test coverage.
- Someone says "write/generate API tests", "validate this response schema".
- A UI test should be replaced by a faster API-level check.
## Workflow
1. **Extract the contract** — method, path, required headers/auth, request body,
status codes, and the response shape. If unknown, ask; don't invent fields.
2. **Design the case matrix:**
- Happy path (valid request → 2xx + correct body).
- Schema validation (assert types/required keys, ideally with Zod).
- Auth (missing/expired token → 401/403).
- Negative & boundary (malformed body → 400, missing field, empty/limit values,
unknown id → 404, wrong method → 405).
3. **Use `request` fixture / `apiRequestContext`** — no browser. Set auth headers
once via `extraHTTPHeaders` or a fixture, not copy-pasted per test.
4. **Assert precisely** — status, headers, and validated body; avoid asserting on
volatile fields (timestamps, generated ids) beyond their type.

How to install
mdr add pramoddutta/aitesterblueprint4x/pw-api-tester@sha256:a44549c438369e5dThe 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.
