Talk from Oct 11th 2016 at LondonCD (https://www.meetup.com/London-Continuous-Delivery)
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 life-cycles 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 cover how Newsweaver (https://www.newsweaver.com/email-overview) has made CDCs part of its pipeline with Pact and how it improved collaboration and confidence between teams when designing APIs.
