| <div class="block">This class makes it easier to write tests to verify the behavior of topologies created with <a href="../../../../org/apache/kafka/streams/Topology.html" title="class in org.apache.kafka.streams"><code>Topology</code></a> or |
| <a href="../../../../org/apache/kafka/streams/StreamsBuilder.html" title="class in org.apache.kafka.streams"><code>StreamsBuilder</code></a>. |
| You can test simple topologies that have a single processor, or very complex topologies that have multiple sources, |
| processors, sinks, or sub-topologies. |
| Best of all, the class works without a real Kafka broker, so the tests execute very quickly with very little overhead. |
| <p> |
| Using the <code>TopologyTestDriver</code> in tests is easy: simply instantiate the driver and provide a <a href="../../../../org/apache/kafka/streams/Topology.html" title="class in org.apache.kafka.streams"><code>Topology</code></a> |
| (cf. <a href="../../../../org/apache/kafka/streams/StreamsBuilder.html#build--"><code>StreamsBuilder.build()</code></a>) and <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Properties.html?is-external=true" title="class or interface in java.util"><code>configs</code></a>, <a href="../../../../org/apache/kafka/streams/TopologyTestDriver.html#createInputTopic-java.lang.String-org.apache.kafka.common.serialization.Serializer-org.apache.kafka.common.serialization.Serializer-"><code>create</code></a> |
| and use a <a href="../../../../org/apache/kafka/streams/TestInputTopic.html" title="class in org.apache.kafka.streams"><code>TestInputTopic</code></a> to supply an input records to the topology, |
| and then <a href="../../../../org/apache/kafka/streams/TopologyTestDriver.html#createOutputTopic-java.lang.String-org.apache.kafka.common.serialization.Deserializer-org.apache.kafka.common.serialization.Deserializer-"><code>create</code></a> and use a <a href="../../../../org/apache/kafka/streams/TestOutputTopic.html" title="class in org.apache.kafka.streams"><code>TestOutputTopic</code></a> to read and |
| verify any output records by the topology. |
| <p> |
| Although the driver doesn't use a real Kafka broker, it does simulate Kafka <a href="../../../../org/apache/kafka/clients/consumer/Consumer.html" title="interface in org.apache.kafka.clients.consumer"><code>consumers</code></a> and |
| <a href="../../../../org/apache/kafka/clients/producer/Producer.html" title="interface in org.apache.kafka.clients.producer"><code>producers</code></a> that read and write raw <code>byte[]</code> messages. |
| You can let <a href="../../../../org/apache/kafka/streams/TestInputTopic.html" title="class in org.apache.kafka.streams"><code>TestInputTopic</code></a> and <a href="../../../../org/apache/kafka/streams/TestOutputTopic.html" title="class in org.apache.kafka.streams"><code>TestOutputTopic</code></a> to handle conversion |
| form regular Java objects to raw bytes. |
| |
| <h2>Driver setup</h2> |
| In order to create a <code>TopologyTestDriver</code> instance, you need a <a href="../../../../org/apache/kafka/streams/Topology.html" title="class in org.apache.kafka.streams"><code>Topology</code></a> and a <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Properties.html?is-external=true" title="class or interface in java.util"><code>config</code></a>. |
| The configuration needs to be representative of what you'd supply to the real topology, so that means including |
| several key properties (cf. <a href="../../../../org/apache/kafka/streams/StreamsConfig.html" title="class in org.apache.kafka.streams"><code>StreamsConfig</code></a>). |
| For example, the following code fragment creates a configuration that specifies a local Kafka broker list (which is |
| needed but not used), a timestamp extractor, and default serializers and deserializers for string keys and values: |
| |
| <pre class="line-numbers"><code> |
| Properties props = new Properties(); |
| props.setProperty(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9091"); |
| props.setProperty(StreamsConfig.DEFAULT_TIMESTAMP_EXTRACTOR_CLASS_CONFIG, CustomTimestampExtractor.class.getName()); |
| props.setProperty(StreamsConfig.DEFAULT_KEY_SERDE_CLASS_CONFIG, Serdes.String().getClass().getName()); |
| props.setProperty(StreamsConfig.DEFAULT_VALUE_SERDE_CLASS_CONFIG, Serdes.String().getClass().getName()); |
| Topology topology = ... |
| TopologyTestDriver driver = new TopologyTestDriver(topology, props); |
| </code></pre> |
| |
| <h2>Processing messages</h2> |
| <p> |
| Your test can supply new input records on any of the topics that the topology's sources consume. |
| This test driver simulates single-partitioned input topics. |
| Here's an example of an input message on the topic named <code>input-topic</code>: |
| |
| <pre class="line-numbers"><code> |
| TestInputTopic<String, String> inputTopic = driver.createInputTopic("input-topic", stringSerdeSerializer, stringSerializer); |
| inputTopic.pipeInput("key1", "value1"); |
| </code></pre> |
| |
| When <a href="../../../../org/apache/kafka/streams/TestInputTopic.html#pipeInput-K-V-"><code>TestInputTopic.pipeInput(Object, Object)</code></a> is called, the driver passes the input message through to the appropriate source that |
| consumes the named topic, and will invoke the processor(s) downstream of the source. |
| If your topology's processors forward messages to sinks, your test can then consume these output messages to verify |
| they match the expected outcome. |
| For example, if our topology should have generated 2 messages on <code>output-topic-1</code> and 1 message on |
| <code>output-topic-2</code>, then our test can obtain these messages using the |
| <a href="../../../../org/apache/kafka/streams/TestOutputTopic.html#readKeyValue--"><code>TestOutputTopic.readKeyValue()</code></a> method: |
| |
| <pre class="line-numbers"><code> |
| TestOutputTopic<String, String> outputTopic1 = driver.createOutputTopic("output-topic-1", stringDeserializer, stringDeserializer); |
| TestOutputTopic<String, String> outputTopic2 = driver.createOutputTopic("output-topic-2", stringDeserializer, stringDeserializer); |
| |
| KeyValue<String, String> record1 = outputTopic1.readKeyValue(); |
| KeyValue<String, String> record2 = outputTopic2.readKeyValue(); |
| KeyValue<String, String> record3 = outputTopic1.readKeyValue(); |
| </code></pre> |
| |
| Again, our example topology generates messages with string keys and values, so we supply our string deserializer |
| instance for use on both the keys and values. Your test logic can then verify whether these output records are |
| correct. |
| <p> |
| Note, that calling <code>pipeInput()</code> will also trigger <a href="../../../../org/apache/kafka/streams/processor/PunctuationType.html#STREAM_TIME"><code>event-time</code></a> base |
| <a href="../../../../org/apache/kafka/streams/processor/ProcessorContext.html#schedule-java.time.Duration-org.apache.kafka.streams.processor.PunctuationType-org.apache.kafka.streams.processor.Punctuator-"><code>punctuation</code></a> callbacks. |
| However, you won't trigger <a href="../../../../org/apache/kafka/streams/processor/PunctuationType.html#WALL_CLOCK_TIME"><code>wall-clock</code></a> type punctuations that you must |
| trigger manually via <a href="../../../../org/apache/kafka/streams/TopologyTestDriver.html#advanceWallClockTime-long-"><code>advanceWallClockTime(long)</code></a>. |
| <p> |
| Finally, when completed, make sure your tests <a href="../../../../org/apache/kafka/streams/TopologyTestDriver.html#close--"><code>close()</code></a> the driver to release all resources and |
| <a href="../../../../org/apache/kafka/streams/processor/Processor.html" title="interface in org.apache.kafka.streams.processor"><code>processors</code></a>. |
| |
| <h2>Processor state</h2> |
| <p> |
| Some processors use Kafka <a href="../../../../org/apache/kafka/streams/processor/StateStore.html" title="interface in org.apache.kafka.streams.processor"><code>state storage</code></a>, so this driver class provides the generic |
| <a href="../../../../org/apache/kafka/streams/TopologyTestDriver.html#getStateStore-java.lang.String-"><code>getStateStore(String)</code></a> as well as store-type specific methods so that your tests can check the underlying |
| state store(s) used by your topology's processors. |
| In our previous example, after we supplied a single input message and checked the three output messages, our test |
| could also check the key value store to verify the processor correctly added, removed, or updated internal state. |
| Or, our test might have pre-populated some state <em>before</em> submitting the input message, and verified afterward |
| that the processor(s) correctly updated the state.</div> |
