(Talk given at London Continuous Delivery meetup group, October 2016 – Continuous Delivery: Monoliths and Microservices)

Autonomy and isolation are some of the core values of microservices, allowing for independent changes and independent deployments. As loosely coupled services interact on interfaces managed under different lifecycles and even different teams, making sure that a simple change did not break the application can turn into an integration nightmare.

Consumer-Driven Contracts testing brings an alternative integration testing approach for distributed systems, relying less on live-like integration environments and more on making interactions explicit and quickly verifiable.
This talk will cover how Newsweaver has made CDCs part of its pipeline with Pact and how it improved collaboration and confidence between teams when designing APIs.
