Pact Contract Testing is one of 8 APIs that [Test Specifications](https://apis.io/providers/test-specifications/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Consumer-Driven Contracts, Contract Testing, and Specification. The published artifact set on APIs.io includes API documentation.

Pact is a consumer-driven contract testing tool where consumers write test specifications (pacts) that define what responses they expect from provider APIs. Providers then verify their implementation satisfies all consumer-authored specifications via the Pact Broker.
