Auto-Generate API Tests From Your OpenAPI Spec
Upload your OpenAPI spec and get a complete test suite with 100% endpoint coverage, contract validation, and fuzz testing, all in under 2 minutes.
Overview
What is AI API testing?
Manually writing API tests for every endpoint, status code, and edge case is tedious and error-prone. AI API testing reads your OpenAPI specification and generates a comprehensive test suite automatically, covering happy paths, error cases, boundary values, and schema validation for every endpoint. Contract tests ensure your API never drifts from its documented specification.
What's included
OpenAPI spec import
Import OpenAPI 3.x or Swagger 2.x specifications. Tests are generated for every path, method, and response schema automatically.
Contract testing
Validate that every API response matches its documented schema. Schema drift is caught before it breaks downstream consumers.
Fuzz testing
Automatically generate malformed, boundary, and unexpected inputs to uncover crashes, leaks, and validation gaps in your API.
Auth scenario coverage
Test authenticated and unauthenticated scenarios, permission boundaries, and token expiry handling across all endpoints.
Dependency mocking
Automatic mocking of downstream services means tests run fast and deterministically without external dependencies.
Diff on spec change
When your OpenAPI spec changes, the test suite updates automatically and highlights new coverage requirements introduced by the change.
How it works
From setup to production
Import
Connect your repository or upload your OpenAPI spec. AI parses the full specification including schemas, security definitions, and examples.
Generate
AI generates tests for every endpoint: happy paths, error codes, boundary values, and fuzz payloads, in your chosen test framework.
Run
Tests run in CI on every PR against a live or mocked API environment. Results are available in under 2 minutes.
Update
When the spec changes, affected tests update automatically. New endpoints generate new tests without any manual intervention.
