OpenAPI Test Matrix Generator
Generate cases for one operation or a complete specification, with every case linked back to a contract path and exportable as CSV, Markdown, or JSON.
How this tool works
A contract is a useful test-design input because it declares required values, JSON types, enum domains, numeric and string boundaries, array sizes, security requirements, and documented responses.
The generator produces positive and negative ideas only where a documented constraint exists. It avoids inventing response codes or business outcomes that the description does not specify.
Examples
- Omit a required request property.
- Exercise minimum and just-below-minimum values.
- Generate present and absent authentication scenarios where security is declared.
Common use cases
From schema keyword to test idea
- required becomes a missing-field case
- enum becomes one case per declared value plus an outside value
- minimum and maximum produce boundary and adjacent invalid cases
- minLength, maxLength, minItems, and maxItems produce size tests
Coverage boundary
Generated rows require expected behavior to be refined against API documentation. A schema can describe admissible shapes, but it cannot guarantee persistence, authorization, ordering, side effects, or implementation conformance.
Failure case: OpenAPI Tests
Invalid/failure example
Generate present and absent authentication scenarios where security is declared.
Expected: The generator produces positive and negative ideas only where a documented constraint exists. It avoids inventing response codes or business outcomes that the description does not specify.

FAQ
Does this tool send the pasted data or execute an API request?
No. Analysis runs in this browser tab. The tool does not call pasted URLs, resolve remote references, or submit the input to a DevPouch processing endpoint.
Is this complete API test coverage?
No. Output is labeled contract-derived test ideas. OpenAPI rarely captures authorization ownership, state transitions, concurrency, rate limits, data dependencies, or every business rule.
Does the tool execute tests?
No. It creates reviewable test ideas and never sends a request to an API.
