Pact JVM
JVM implementation of Pact for consumer-driven contract testing, providing mock services and verification tools.
What is Pact JVM?
Pact-JVM is a JVM-based implementation of the Pact consumer-driven contract testing framework. It allows service consumers to define expected interactions with providers through a mock service and DSL, then verifies those contracts against the actual provider implementation. This approach enables teams to test both sides of an integration point using fast unit tests rather than slow, brittle end-to-end tests.
JVM developers and teams building microservices or distributed systems who need reliable integration testing between services, particularly those using Java, Kotlin, Scala, or Groovy.
Pact-JVM provides a standardized, language-agnostic way to implement consumer-driven contract testing on the JVM, with extensive framework support and tooling integration. It enables teams to catch integration issues early, reduce testing complexity, and improve deployment confidence without requiring full staging environments.
Overview
