Example 6 with TEST_VALUE

use of brave.kafka.streams.KafkaStreamsTracingTest.TEST_VALUE in project brave by openzipkin.

the class ITKafkaStreamsTracing method should_create_spans_from_stream_with_tracing_mark_as_not_filtered_predicate_true.

@Test
public void should_create_spans_from_stream_with_tracing_mark_as_not_filtered_predicate_true() {
    String inputTopic = testName.getMethodName() + "-input";
    String outputTopic = testName.getMethodName() + "-output";
    StreamsBuilder builder = new StreamsBuilder();
    builder.stream(inputTopic, Consumed.with(Serdes.String(), Serdes.String())).transformValues(kafkaStreamsTracing.markAsNotFiltered("filterNot-1", (key, value) -> true)).filterNot((k, v) -> Objects.isNull(v)).to(outputTopic, Produced.with(Serdes.String(), Serdes.String()));
    Topology topology = builder.build();
    KafkaStreams streams = buildKafkaStreams(topology);
    send(new ProducerRecord<>(inputTopic, TEST_KEY, TEST_VALUE));
    waitForStreamToRun(streams);
    MutableSpan spanInput = testSpanHandler.takeRemoteSpan(CONSUMER);

    assertThat(spanProcessor.tags()).containsEntry(KAFKA_STREAMS_FILTERED_TAG, "true");
    // the filterNot transformer returns true so record is dropped
    streams.close();
