API Contract Testing

Test Every Endpoint Automatically

Point QuantumVerifi at your OpenAPI or Swagger spec — it generates and executes contract tests for every endpoint, verifying responses match your schema.

What It Does

QuantumVerifi reads your API specification and generates comprehensive contract tests that verify:

  • Status codes — Correct responses for valid and invalid requests
  • Response schemas — Response bodies match your documented structure
  • Error handling — Proper error responses for edge cases
  • Authentication — Protected endpoints require valid credentials
  • CRUD flows — Create, read, update, and delete operations work end-to-end

How to Use It

Provide your OpenAPI/Swagger specification URL and optionally a base URL for live execution:

Spec: https://api.example.com/docs/openapi.json
Base URL: https://api.example.com/v1

QuantumVerifi analyses every endpoint, generates test suites grouped by resource, and optionally executes them against your live API.

What You Get

  • Test files — Ready-to-run Jest or Pytest test suites
  • Coverage report — Percentage of endpoints with test coverage
  • Execution results — Pass/fail for each endpoint (when live execution is enabled)
  • Quality grade — A through F based on test quality and coverage
  • Self-healing — Failed tests are automatically analysed and regenerated

Supported Formats

  • OpenAPI 3.x (JSON and YAML)
  • Swagger 2.0
  • Any publicly accessible or authenticated spec URL

Live Execution

When you provide a base URL, QuantumVerifi executes the generated tests against your live API in an isolated sandbox. Each test uses unique identifiers to avoid data conflicts, and cleanup is handled automatically.

Tests that fail against the live API trigger self-healing — the system analyses the failure, adjusts the test, and retries up to 3 times.
