SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Implementer teams suffer from brittle integrations due to missing or evolving API contracts; contract testing with Pact ensures providers meet consumer expectations without end-to-end tests.

Core Features & Use Cases

Pact-based contract testing: Create and verify consumer-provider contracts locally and in CI.
Broker-driven verification: Publish and verify contracts via a Pact Broker to coordinate across teams.
Independent evolution: Allow services to evolve independently while guarding against breaking changes.

Quick Start

Run the consumer Pact tests to generate contracts.

FAQPage Schema

What is consumer-driven contract testing and how does it enforce API reliability?▼

Consumer-driven contract testing verifies that API providers meet consumer expectations by defining and agreeing on API contracts. It uses Pact to create and verify these contracts locally and in CI, guarding against breaking changes without requiring end-to-end tests.

How do I set up Pact tests to generate and verify API contracts?▼

To set up Pact contract testing, write consumer tests to generate contract files, then configure provider verification tests to validate those contracts against the provider API. This requires Pact libraries and test scaffolding for both consumers and providers.

Can I use a Pact Broker to coordinate contract verification across microservices teams?▼

Yes, you can use a Pact Broker to publish and verify contracts, enabling broker-driven collaboration across microservices teams. It coordinates contract sharing and verification results, allowing services to evolve independently while preventing integration failures.

Do I need end-to-end tests if I implement contract testing with Pact?▼

Contract testing with Pact eliminates the need for brittle end-to-end integration tests. By verifying consumer-provider contracts directly, it ensures reliable API evolution and guards against breaking changes in microservices ecosystems.

What is the best way to prevent breaking API changes in a microservices architecture?▼

The best way to prevent breaking API changes is implementing consumer-driven contract testing with Pact. It allows services to evolve independently by defining strict API contracts and verifying them in CI, avoiding the heavy overhead of end-to-end tests.

Why should I use consumer-driven contract testing instead of end-to-end integration tests?▼

Consumer-driven contract testing replaces end-to-end integration tests to solve brittle integrations caused by evolving API contracts. It verifies individual consumer expectations against the provider locally, enabling independent service evolution without slow, fragile end-to-end test suites.
