Standalone stub server using Spring Cloud Contract WireMock

Creating a standalone stub server is important in order not to depend on an API that isn’t yet available, isn’t complete, or is expensive to access during the development phase. The front-end team can easily advance its functionality by simulating all the requests and responses that will be produced by the APIs later.
