SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill eliminates the need for brittle, slow, and flaky end-to-end integration environments by enabling consumer-driven contract testing that catches integration breakages during the CI process.

Core Features & Use Cases

  • Consumer-Driven Contracts: Allows consumers to define their requirements, ensuring providers only break builds when they violate actual usage.
  • Deployment Gating: Uses can-i-deploy to prevent shipping code that would break existing service dependencies in production.
  • Use Case: When a frontend team needs to ensure their API calls remain compatible with a backend service, this skill automates the verification of request/response schemas without requiring both services to be deployed in a shared staging environment.

Quick Start

Use the contract-testing skill to generate a new Pact file for the current service interaction and verify it against the provider's latest contract.

FAQPage Schema
How does consumer-driven contract testing validate microservices integration?

Consumer-driven contract testing validates microservices integration by allowing consumers to define their API expectations, ensuring providers only break builds when they violate actual usage without requiring full end-to-end environments.

How do I prevent deploying API changes that break existing service dependencies in CI/CD?

You can prevent deploying breaking API changes by using the can-i-deploy deployment gating mechanism to verify compatibility matrices against consumer expectations before shipping code to production.

Can I verify API request and response schemas without deploying services to a shared staging environment?

Yes, you can verify API request and response schemas without a shared staging environment by generating and verifying Pact files against the provider's latest contract at unit-test speed during the CI process.

Does this contract-testing approach work with Spring Cloud Contract or only Pact?

This approach works with both Pact and Spring Cloud Contract to facilitate consumer-driven contracts and gate deployments based on verified compatibility matrices between independently deployed services.

Why should I replace end-to-end integration tests with contract testing for microservices?

You should replace end-to-end integration tests with contract testing to eliminate brittle, slow, and flaky staging environments while catching integration breakages early during the CI process at unit-test speed.

How do I generate a new Pact file for a service interaction and verify it against the provider?

To generate a new Pact file for a service interaction, use the contract-testing skill to define consumer expectations and then verify the generated contract against the provider's latest contract to ensure compatibility.
