FAQPage Schema

How do I prevent API contract drift between microservices?▼

You prevent API contract drift by validating consumer expectations against providers using consumer-driven contract testing. This verifies service boundaries and ensures providers meet consumer requirements before deployment.

What is consumer-driven contract testing and how does it work with Pact?▼

Consumer-driven contract testing validates API interactions by having consumers define expected responses, then verifying providers against those expectations. It uses Pact to coordinate contracts across microservices architectures.

How do I integrate contract testing into a CI/CD pipeline?▼

Contract testing integrates into CI/CD pipelines by automating provider verification and blocking deployments that introduce breaking changes. This validates consumer expectations automatically during the build process.

Can I use OpenAPI schema validation for contract testing?▼

Yes, OpenAPI schema validation is supported for contract testing alongside Pact. You can validate consumer expectations against providers and perform backward compatibility checks using OpenAPI definitions.

Does contract testing support semantic versioning and backward compatibility checks?▼

Yes, contract testing supports semantic versioning and backward compatibility checks. It validates that API changes maintain compatibility with existing consumer expectations across service boundaries.

What is the best way to coordinate API contracts across multiple teams?▼

The best way to coordinate API contracts across teams is using consumer-driven contract validation with automated verification. This prevents drift by ensuring providers meet consumer expectations through multi-agent orchestration in CI/CD pipelines.
