Spring cloud contract - integrating with non - spring endpoint

Question

I have a spring webapp that communicates with external service over kafka. IS it possible to somehow test contract between those services?

Answer 1

Yes you can. Spring Cloud Contract supports CDC with messaging. If you're using Spring Cloud Stream - the work to be done is trivial. If not then you'll have to implement your own as presented in this issue - Spring Cloud Contract and plain Spring AMQP . Summing it up it's enough for both consumer and producer to implement a custom org.springframework.cloud.contract.verifier.messaging.MessageVerifier bean that will be responsible for receiving and sending of messages via Kafka
