- YES kafka streams should work such that the inputs and outputs generated by your "Kafka testing module" would be identical to what is expected by the next service. But looking at those interfaces (putting the pipes together) and making sure they work too is literally one of the most important parts of your job.
- Feb 05, 2019 · To stress-test our system in general and the Kafka clusters specifically, we developed an application which constantly generates message batches of random bytes to a cluster’s front-end. This application spins 100 threads to send 1,000 messages of 1 KB random data to each topic, in 5 ms intervals.
- This report describes the test configuration, scenarios, and results in rows-per-second throughput for replicating data from a Db2 for z/OS database into a Kafka landing zone. The source engine is running CDC for z/OS on z/OS and the target is running CDC for Kafka on x8_64 RHEL.
- Dec 19, 2019 · Kafka producers write to topics. Kafka consumers read from topics. A topic is associated with a log, which is a data structure on disk. Kafka appends records from a producer(s) to the end of a topic log. A topic log consists of many partitions that are spread over multiple files. These files are, in turn, spread across multiple Kafka cluster nodes.
- Test Harness in Software Testing. Test Harness in Software Testing is a collection of stubs, drivers and other supporting tools required to automate test execution. Test harness executes tests by using a test library and generates test reports.

The most basic test is just to test the integration. Therefore you need to use Kafka to publish a message and afterward you could read the message from the topic. You need to annotate your test class with at least the following annotations: @RunWith(SpringRunner.class) @SpringBootTest @EmbeddedKafka public class SimpleKafkaTest { }
