Example 1 with KafkaProducer

use of io.vertx.kafka.client.producer.KafkaProducer in project hono by eclipse.

the class CachingKafkaProducerFactoryTest method setUp.

@BeforeEach
void setUp() {
    final VertxInternal vertxMock = mock(VertxInternal.class);
    final ContextInternal context = VertxMockSupport.mockContextInternal(vertxMock);
    final PromiseInternal<Void> promiseInternal = VertxMockSupport.promiseInternal();
    when(promiseInternal.future()).thenReturn(Future.succeededFuture());
    doAnswer(invocation -> {
        return promiseInternal;
    }).when(context).promise();
    when(vertxMock.getOrCreateContext()).thenReturn(context);
    doAnswer(invocation -> {
        final Promise<Object> result = Promise.promise();
        final Handler<Future<Object>> blockingCode = invocation.getArgument(0);
        final Handler<AsyncResult<Object>> resultHandler = invocation.getArgument(1);
        result.future().onComplete(resultHandler);
        blockingCode.handle(result.future());
        return null;
    }).when(context).executeBlocking(VertxMockSupport.anyHandler(), VertxMockSupport.anyHandler());
    final BiFunction<String, Map<String, String>, KafkaProducer<String, Buffer>> instanceSupplier = (n, c) -> {
        final MockProducer<String, Buffer> mockProducer = new MockProducer<>(true, new StringSerializer(), new BufferSerializer());
        return KafkaProducer.create(vertxMock, mockProducer);
    };
    factory = CachingKafkaProducerFactory.testFactory(vertxMock, instanceSupplier);
    configProperties.setProducerConfig(Map.of("bootstrap.servers", "localhost:9092"));
