Spring Consumer Driven Contract Development Workbench

This workbench demonstrates how to do consumer driven contract development (CDC) by using the Spring Cloud Contract Verifier.

It is inspired by a talk from Josh Long given on October, 3rd 2018 on YouTube for the v JUG.

You can find Joshs example using reactive paradigms at GitHub: bootiful-testing

This workbench contains an application offering a REST api (producer) and another application that implements a client to access this service (consumer).

Building and Testing the Producer and its Stubs

The contract stubs are build and tested by a regular gradle build.

If you want to perform the generation of contract tests as a separate task, you can use the following command:

$ ./gradlew :contract-producer:generateContractTests :contract-producer:test

The following command will then publish the generated (and tested) stubs to the local maven repository:

$ ./gradlew :contract-producer:publishToMavenLocal

Build and Test the Consumer

To build and test the consumer use ./gradlew :contract-consumer:check. This will pull the test stubs generated by the producer from the local maven repository and use them for running the tests.
