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
Consumers point of view.
Pact is a testing tool that guarantees those
Contracts are satisfied.
|Confidence||Faster||Less Error Prone|
|Continuously evolve your codebase knowing that Pact will guarantee Contracts are met.||No need to setup end-to-end environments. No need for manual testing.||Generation and verification of Contracts are automatically managed by Pact.|
I still need convincing.
