Collaborating with Contracts

on YouTube ↗22m

" summary

Shows that consumer-driven contracts catch real breaks (removing a name field that still powers two consumers) and enable parallel work across many services by making expectations explicit and executable. Demonstrates the pact gem workflow: consumer tests run a mock server, emit a JSON pact, then pact verify fires real HTTP at the provider and runs full-stack checks. Describes provider states for setup (example: inserting 10,000 friends) and warns about how much to assert and integration with CI.
