The Pact family of frameworks provide support for Consumer Driven Contracts testing.
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.
|Confidence||Faster turnaround||Less Error Prone|
|Continuously evolve your codebase knowing that Pact will guarantee contracts are met.||Find out before you deploy whether or not your applications will work together - no need to wait for slow e2e tests.||Generation and verification of contracts are automatically managed by Pact.|
I still need convincing.
