Quarkus: How to test a service that integrates with kafka?

Created on 6 Jan 2020  路  16Comments  路  Source: quarkusio/quarkus

I hope this is not extremely out of topic, but I'm trying to figure out the best way to consume a Kafka test message and compare it to an expected message.

A few thoughts (that might be wrong):

  • I think that it's possible to inject an already configured (from application.properties) KafkaConsumer (actually I'm not sure It is possible to Inject a consumer which is not with the reactive extension at all..)
  • I don't see how I use Reactive Messaging as part of a test - writing a method with @Incoming doesn't seem to fit this use case
  • Since the actual producer is a reactive method I don't know how to capture the sent data...
  • It is possible to create an external project just for IT but I wonder if there's a better way since I'll have to externally start the service and then run the tests. And I feel there's a better way

I'm stuck with these tests at the moment. I'd be happy for some help on how to do that...

@FreifeldRoyi did you look at https://github.com/quarkusio/quarkus-quickstarts/blob/master/kafka-quickstart/src/test/java/org/acme/quarkus/sample/PriceResourceTest.java?

Also in the upcoming version of SmallRye reactive messaging, we provide an in-memory connector that simplifies these tests (and about using kafka broker)

@cescoffier how to override Kafka connector with in-memory connector? I tried mp.messaging.incoming.some_topic.connector=smallrye-in-memory but I got

2020-01-28 08:20:16,107 ERROR [io.sma.rea.mes.imp.ConfiguredChannelFactory] (main) Unable to create the publisher or subscriber during initialization: java.lang.IllegalArgumentException: Unknown connector for some_topic.

It seems there is no io/smallrye/reactive/messaging/connector/InMemoryConnector.java class in in quarkus-smallrye-reactive-messaging*.

Yes, it's not released yet.

cescoffier picture cescoffier on 28 Jan 2020

Do you have a rough estimate when it will be released?

SmallRye reactive messaging 2.0.1 was release and I tried https://smallrye.io/smallrye-reactive-messaging/smallrye-reactive-messaging/2/testing/testing.html with quarkus 1.4.1. But I get the exception:

You are right, some recent change broke it. I will fix it before next release.

_For the record:_ It requires the in-memory connector to be indexed.

Now I get java.lang.IllegalArgumentException: Unknown channel computations when calling connector.sink("computations"); in the test.
I think the channels are configured and connected before the @BeforeAll is called and so the in-memory connector is not used.
Log output before @BeforeAll is called in a @QuarkusTest

You can see INFO: AMQP broker configured to localhost:5672 for channel computations that the channel "computations" uses the amqp connector.

Workaround:
Adding %test.mp.messaging.outgoing.computations.connector=smallrye-in-memory to the application.properties solve the problem.

It's still not integrated in Quarkus. I'm going to open the PR today.

cescoffier picture cescoffier on 3 May 2020

You also need to switch the channel as indicated on https://smallrye.io/smallrye-reactive-messaging/smallrye-reactive-messaging/2/testing/testing.html.

cescoffier picture cescoffier on 3 May 2020

I called InMemoryConnector.switchOutgoingChannelsToInMemory("computations"); here is the source code: https://github.com/VirtualProgrammingLab/viplab-websocket-api/blob/test-parameters/websocket-api-impl/src/test/java/de/uni_stuttgart/tik/viplab/websocket_api/ComputationWebSocketTest.java#L60

Legion2 picture Legion2 on 3 May 2020

Did you try from a Quarkus Test Resource, as @BeforeAll might be called after the application start?

@cescoffier I don't know what you mean by "Quarkus Test Resource", I have a test class annotated with @QuarkusTest and a method annotated with @BeforeAll which switch to in memory connector and a method annotated with @Test. I stepped through the test with the debugger and the @BeforeAll method is called but I think to late.

@Legion2 something like https://github.com/quarkusio/quarkus-quickstarts/blob/master/kafka-quickstart/src/test/java/org/acme/kafka/KafkaResource.java, but instead of starting a container, switch the channels.

@Legion2 something like:

/**
 * Use the in-memory connector to avoid having to use a broker.
 */
public class FakeKafkaResource implements QuarkusTestResourceLifecycleManager {

    @Override
    public Map<String, String> start() {
        Map<String, String> env = new HashMap<>();
        Map<String, String> props1 = InMemoryConnector.switchIncomingChannelsToInMemory("prices");
        Map<String, String> props2 = InMemoryConnector.switchOutgoingChannelsToInMemory("my-data-stream");
        env.putAll(props1);
        env.putAll(props2);
        return env;
    }

    @Override
    public void stop() {
         InMemoryConnector.clear();
    }
}
