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

01

Import

Connect your repository or upload your OpenAPI spec. AI parses the full specification including schemas, security definitions, and examples.

02

Generate

AI generates tests for every endpoint: happy paths, error codes, boundary values, and fuzz payloads, in your chosen test framework.

03

Run

Tests run in CI on every PR against a live or mocked API environment. Results are available in under 2 minutes.

04

Update

When the spec changes, affected tests update automatically. New endpoints generate new tests without any manual intervention.
