Example 1 with SQS

use of org.testcontainers.containers.localstack.LocalStackContainer.Service.SQS in project beam by apache.

the class SnsIOIT method testWriteThenRead.

@Test

    ITOptions opts = env.options();
    int rows = opts.getNumberOfRows();
    // Write test dataset to SNS
    pipelineWrite.apply("Generate Sequence", GenerateSequence.from(0).to(rows)).apply("Prepare TestRows", ParDo.of(new DeterministicallyConstructTestRowFn())).apply("Write to SNS", SnsIO.<TestRow>write().withTopicArn(resources.snsTopic).withPublishRequestBuilder(r -> PublishRequest.builder().message(r.name())));
    // Read test dataset from SQS.
    PCollection<String> output = pipelineRead.apply("Read from SQS", SqsIO.read().withQueueUrl(resources.sqsQueue).withMaxNumRecords(rows)).apply("Extract message", MapElements.into(strings()).via(SnsIOIT::extractMessage));
    PAssert.thatSingleton(output.apply("Count All", Count.globally())).isEqualTo((long) rows);
    PAssert.that(output.apply(Combine.globally(new HashingFn()).withoutDefaults())).containsInAnyOrder(getExpectedHashForRowCount(rows));
    pipelineWrite.run();
    pipelineRead.run();
