My application uses Kafka and Hibernate. For Kafka a running docker image is required. If I run a Quarkus test for Hibernate, the test fails if Kafka is not running. In my IDE this is not a problem, but in Jenkins there is no Kafka server available and the test fails because it cannot resolve the Kafka server.
Is it possible to disable Kafka in Quarkus tests?
You could make use of Microprofile's Emitter for sending messages to Kafka channel:
@Inject
@Channel("hello")
Emitter<String> emitter;
By default, in case when there is no Kafka behind that emitter, it will create an in-memory message bus. So the docker image for Kafka would not be required.
Another solution would be to use KafkaContainer from TestContainers to create a throwaway Kafka container for each test run.
You could check both examples in Alex Soto's repository.
Look at CheckoutProcess class and corresponding component test and integration test.
