SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires zod, and includes scripts (resource) components.

What problem does it solve?

Contract testing ensures API contracts between services are preserved across deployments, preventing integration failures when teams evolve microservices and APIs.

Core Features & Use Cases

  • Consumer-driven contracts using Pact and provider verification
  • Schema validation and OpenAPI contract checks
  • Schema evolution strategies and breaking-change detection
  • CI/CD integration and can-i-deploy style gates
  • Versioned contracts across API versions to support migrations

Quick Start

Integrate contract tests into your CI pipeline and begin validating consumer/provider contracts against your real services.

Frequently Asked Questions about contract-test

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate API contract testing to prevent breaking changes in microservices?▼

API contract testing prevents breaking changes by validating consumer-driven contracts and provider verification. You apply schema validation and OpenAPI checks to ensure compatibility across evolving services before deployment.

What is the best way to integrate Pact contract verification into a CI/CD pipeline?▼

Integrating Pact into CI/CD involves automating consumer-driven contracts and provider verification as pipeline gates. This applies can-i-deploy style checks to block deployments if API compatibility is broken.

Does contract testing work with OpenAPI schema validation for evolving APIs?▼

Contract testing works directly with OpenAPI schema validation to manage evolving APIs. It enforces schema evolution strategies and detects breaking changes to maintain compatibility across versioned contracts during migrations.

How do I validate consumer-driven contracts before a production deployment?▼

Validating consumer-driven contracts before production requires applying schema validation and provider verification. Integrating these contract tests into CI/CD pipelines ensures incompatible changes are caught prior to deployment.

Do I need zod to perform schema validation for contract testing?▼

You need zod to perform schema validation within this contract testing workflow. It supports the schema validation and OpenAPI contract checks required to ensure compatibility across your evolving services.

When should I use consumer-driven contracts instead of end-to-end integration tests?▼

Consumer-driven contracts should be used when teams evolve microservices independently and need to prevent integration failures. This approach validates API contracts across deployments without the overhead of end-to-end tests.
