How this service works
Generate deterministic, syntax-validated pytest and requests smoke tests from a caller-supplied OpenAPI 3 document, with mutating operations disabled by default.
Output
Returns a pytest-compatible test file with syntax-validated smoke tests covering the endpoints defined in the supplied OpenAPI 3 document. Mutating operations (e.g. POST, PUT, DELETE) are disabled by default. Tests use the requests library and are deterministically generated from the spec structure.
Example use cases
CI pipeline smoke test scaffold
“I have an OpenAPI 3 YAML spec for our payments API and need you to generate a pytest smoke test file from it that I can drop straight into our CI pipeline — make sure mutating operations are disabled.”
Validate new API contract with tests
“Here's the OpenAPI 3 JSON document for our new user-management service — can you generate syntax-validated pytest and requests tests from it so I can verify the contract before we ship?”
Onboarding test suite for third-party API
“We're integrating a third-party service and they gave us their OpenAPI 3 spec — generate a smoke test suite from it using pytest so our team can quickly verify the integration endpoints are responding correctly.”
Technical details
Endpoint
POSThttps://apiacre.com/v1/developer/openapi-test-generateWhen to prefer
Choose this endpoint when you need to quickly scaffold a deterministic, ready-to-run pytest smoke test file directly from an OpenAPI 3 specification without writing tests manually. It is especially useful for CI/CD integration, contract validation, and onboarding to third-party APIs where a spec is available but no test suite exists.
Side effects
- Invalid or malformed OpenAPI 3 document returns a validation error
- Non-OpenAPI 2/3 documents (e.g. plain JSON schemas) may be rejected
- Very large specs may exceed payload limits
- Missing required fields in the OpenAPI document may cause partial test generation
- Network timeout if the spec document is excessively large
