What is Pact?
The Pact family of frameworks provide support for Consumer Driven Contracts testing.
Consumer Driven Contracts
Contract is a collection of agreements between a client (
Consumer) and an API (
Provider) that describes the interactions that can take place between them.
Consumer Driven Contracts is a pattern that drives the development of the
Provider from its
Consumer's point of view. It is TDD for services.
Pact is a testing tool that helps you write
Contracts, and guarantees those
Contracts are satisfied.

I still need convincing.
