Executable Agreements: Code, Collaborate, and Deploy with Confidence
This talk introduces contract testing with Pact as a scalable alternative to end-to-end tests, addressing integration failures in distributed systems. It explores executable agreements—validated automatically in CI—to catch mismatches early, fitting into modern workflows and enhancing collaboration while complementing unit and integration tests.

In a world of distributed systems, microservices, and fast-paced deployments, integration failures are still a leading cause of production issues. End-to-end tests are often too slow, flaky, and expensive to be your safety net.
This talk introduces contract testing with Pact as a practical, scalable alternative that lets teams define and verify API expectations early, independently, and reliably. We’ll walk through the concept of executable agreements—living contracts between services that are validated automatically in CI, catching mismatches before they reach production. We’ll see how contract testing fits into modern development workflows, how it complements unit and integration tests, and why it fosters better collaboration between teams.
