What is the main benefit of using this skill?

It helps you design and implement contract testing to catch breaking API changes early, reducing reliance on slow, expensive, and flaky end-to-end tests.

Does this skill support specific programming languages?

While the principles apply broadly to any language, the skill includes specific implementation guidance and references for .NET using PactNet.

How does this help with CI/CD integration?

It provides established patterns for integrating Pact Broker and verification gates into your automated pipelines to block incompatible deployments.

Can I use this for asynchronous or event-driven architectures?

Yes, the skill provides specific guidance on using Pact Message for testing asynchronous message and event-driven contract scenarios.

Security & Testing

Architects consumer-driven contract testing strategies using Pact to ensure API stability and prevent breaking changes.

About

This skill empowers developers to implement robust Consumer-Driven Contract (CDC) testing workflows, specifically focusing on the Pact ecosystem. It provides comprehensive guidance on designing contract testing strategies, writing consumer tests, verifying provider contracts, and managing API evolution through contract-first approaches. By establishing clear agreements between services, it helps teams reduce deployment risks, eliminate flaky end-to-end tests, and maintain high confidence in distributed microservices architectures.

Key Features

Implementation guidance for .NET and asynchronous message contracts
Breaking change detection and API evolution management
Comparative analysis of E2E, integration, and contract testing scopes
Consumer-driven contract (CDC) strategy design and service mapping
Pact Broker integration and CI/CD pipeline automation patterns
12 GitHub stars

Use Cases

Establishing a contract-first design approach for new microservices
Integrating Pact verification gates into GitHub Actions or CI/CD pipelines
Refactoring internal APIs without impacting downstream consumers
