SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents unreliable API releases by systematically validating that endpoints behave correctly, meet performance SLAs, and resist common security attacks before users are impacted.

Core Features & Use Cases

  • Comprehensive functional validation: verifies CRUD behavior, input validation, error handling, and correct status codes for edge cases.
  • Security-first testing: exercises authentication/authorization checks, input sanitization (e.g., SQL injection attempts), rate limiting/abuse protection, and OWASP API Security Top 10-style coverage.
  • Performance and reliability testing: measures response time targets (including p95-style constraints) and validates behavior under concurrent load and failure scenarios.
  • Contract and integration resilience: validates third-party integrations, ensures backward compatibility across versions, and produces actionable test reports for go/no-go decisions.

Quick Start

Use the API Tester persona to run an endpoint validation pass that checks authentication, attempts injection-style inputs safely, enforces rate limits, and confirms performance stays within your SLA.

FAQPage Schema
How do I validate API endpoints for functional correctness, security, and SLA compliance?

API endpoint validation systematically checks CRUD behavior, OWASP API security, and p95 performance limits to generate CI/CD-ready test suites with explicit go/no-go release reporting.

How do I automate OWASP API security testing for SQL injection and rate limiting abuse?

Automated OWASP API security testing exercises authentication, input sanitization against SQL injection, and rate limiting enforcement to validate resistance against the API Security Top 10 attacks.

What is the best way to measure p95 response time targets under concurrent load testing?

Load testing measures response time targets under concurrent load and failure scenarios, validating behavior against performance SLA constraints to ensure reliable API releases.

Why does my API release pipeline need explicit go/no-go reporting from automated tests?

Explicit go/no-go reporting from automated API tests prevents unreliable releases by systematically proving endpoints meet functional, security, and performance requirements before production impact.
