Schema-Aware AI Test Generation

Generate a structured test suite from OpenAPI, Swagger, WSDL, GraphQL or Postman with one click, with or without an AI key.

What It Does

Schema-Aware Test Generation reads your API specification to understand every endpoint, parameter and data model, then plans the tests that should exist and fills each one with a concrete request and assertions, without you writing a single test by hand. Because the plan comes from a declared matrix of scenario classes rather than free-form prompting, every test traces to a scenario and a coverage dimension, and teams that cannot send specs to an AI provider still get the whole suite. With an AI key configured, two bounded calls per endpoint polish the tests and propose up to eight further edge cases, each grounded in a declared constraint. Requirements you have extracted add business-rule tests, and an uploaded Excel test-data sheet spreads real rows across the positive tests. The platform tracks two levels of coverage, Overall and Production-Grade, and "Generate tests for gaps" fills whatever your project settings allow.

An OpenAPI spec for an Orders API is read by AI, which generates a happy path, an edge case, a negative and an auth test, each passing, while endpoint coverage fills to 100%

Overview

The platform reads every endpoint, parameter and constraint in your OpenAPI, Swagger, WSDL, GraphQL or Postman definition and plans the tests that should exist: 79 scenario classes across 12 dimensions, from valid requests and boundaries to 13 authentication-bypass checks. AI (optional, with your key) then polishes names and realistic values and adds up to eight extra edge cases per endpoint; it can never delete or weaken a planned test. Security probes are opt-in per project. Each generated test carries a severity rating, a descriptive name and assertions tailored to the schema, and regenerating updates tests in place, so run history is kept and duplicates do not pile up.

Key Capabilities

Imports OpenAPI 3.x (3.1 included), Swagger 2.0, WSDL, GraphQL SDL or introspection, Postman collections and pasted cURL
Works with no AI key: the full structured suite is planned deterministically
79 scenario classes across 12 dimensions, including 13 authentication-bypass checks
Covers happy paths, negative tests, boundary values and error codes
Severity ratings (Critical, High, Medium, Low) and per-project technique and severity filters
Regeneration updates tests in place by intent, keeping run history

How It Works

  1. 1

    Import your specification from a URL, a file, pasted cURL or text

  2. 2

    The platform reads endpoints, request schemas, response models and constraints

  3. 3

    Click "Generate tests" for one endpoint, or "Generate Tests for All" for a whole feature

  4. 4

    Review the summary and coverage; use "Generate tests for gaps" to close what is missing

  5. 5

    Edit any test, or add manual tests alongside the generated ones
