Overview

What this engagement covers.

We build automated API test suites covering schema validation, authentication flows, error handling, and boundary conditions. For microservice architectures, consumer-driven contract testing with Pact ensures integration contracts are verified independently.

Schema validation

Request/response shapes validated against OpenAPI/Swagger specs.

Auth flow testing

OAuth, JWT, API key, and session-based auth flows covered.

Contract testing (Pact)

Consumer-driven contracts verified independently of service deployment.

Error and boundary coverage

4xx/5xx handling, rate limiting, and edge-case inputs all exercised.

CI integration

API tests run in pipeline as a blocking gate on every service deploy.
