WHAT WE DO

API validation that prevents integration failures before they cascade

We test APIs at every layer — functional correctness, contract compliance, error handling, performance and security — ensuring your services integrate seamlessly, scale reliably and never break the consumer experience.

CAPABILITIES

What we deliver

End-to-end API testing capabilities that validate functionality, contracts, performance and security across every endpoint and integration.

Functional API Testing

Validation of request/response correctness, status codes, payload structures, business logic and error handling for every endpoint.

Contract & Schema Validation

Automated verification of OpenAPI, Swagger, GraphQL schema and JSON schema compliance — preventing breaking changes.

Integration & End-to-End Testing

Cross-service validation that ensures APIs work together correctly — covering authentication, data flow, state management and callbacks.

API Performance Testing

Load, stress and spike testing of API endpoints — validating latency, throughput and stability under concurrent user volumes.

API Security Testing

Authentication, authorisation, input validation, injection testing and rate limiting validation — securing every endpoint against abuse.

API Monitoring & Mocking

Continuous health checks, synthetic monitoring and service mocking — enabling parallel development and production reliability.

HOW WE TEST

A structured path to release confidence

A quality engineering process where every endpoint is validated for correctness, contract compliance and resilience — before integration failures reach production.

Why it works
  • Contract validation prevents breaking changes
  • Automated coverage across REST, GraphQL and gRPC
  • Performance validation at the API layer
Typical engagement start 1 week
01

Requirement & Risk Assessment

We review API documentation, service architecture, integration points and identify high-risk endpoints and consumer dependencies.

02

API Test Strategy & Planning

We define coverage targets, contract validation rules, performance benchmarks and security checks tailored to your API landscape.

03

Test Design & Automation Build

We design test cases, build automation suites, configure contract validation and set up mocking for dependent services.

04

Execution & Defect Analysis

We run functional, contract and integration tests — validating responses, catching schema drift and logging defects with reproduction steps.

05

Performance & Security Validation

We validate API latency under load, test authentication flows, check rate limiting and probe for injection vulnerabilities.

06

Release Validation & Monitoring

We confirm release readiness with API coverage reports, then set up continuous monitoring and synthetic health checks.

Why Prismberry
