This is an example of a Java kafka consumer that uses Pact, PactFlow and GitHub Actions to ensure that it is compatible with the expectations its consumers have of it.
The project uses a Makefile to simulate a very simple build pipeline with two stages - test and deploy.
See the canonical consumer example here: https://github.com/pactflow/example-consumer See also the full PactFlow CI/CD Workshop for which this can be substituted in as the "consumer".
In the following diagram, we'll be testing the "Product API", a simple HTTP service that exposes product information as a REST API, which is fed events from an Event API on the product topic.
Software:

- Running the API and kafka listener locally:
make start - Producing test events into the
producttopic:make test-events - Retrieve latest products:
