Spring Cloud Stream Testing with Embedded Kafka Broker Sample
|
|
==============================================================
|
|
|
|
In this *Spring Cloud Stream* sample, an embedded kafka broker is used for testing.
|
|
|
|
## Requirements
|
|
|
|
To run this sample, you will need to have installed:
|
|
|
|
* Java 8 or Above
|
|
|
|
## Code Tour
|
|
|
|
This sample is a Spring Boot application that uses Spring Cloud Stream to receive a `String` message and forward an upper case version of that String; it uses the Kafka binder.
|
|
|
|
* EmbeddedKafkaApplication - the Spring Boot Main Application
|
|
* EmbeddedKafkaApplicationTests - the test case
|
|
|
|
The `spring-kafka-test` dependency added to the `pom.xml` puts the `KafkaEmbedded` JUnit `@Rule` on the class path.
|
|
Refer to the [Spring for Apache Kafka Reference Manual](http://docs.spring.io/spring-kafka/reference/htmlsingle/#testing) for more information about this.
|
|
Notice how the `@BeforeClass` method sets up the Boot and binder properties to locate the servers.
|
|
|
|
See the test method for the details on interacting with Embedded Kafka.
|
|
The test method starts by sending a message to the input destination.
|
|
It then creates a consumer to consume from the output destination; gets the output message and asserts that it's an upper case version of the sent message.
|
|
|
|
## Building with Maven
|
|
|
|
Build the sample and run the test by executing:
|
|
|
|
`./mvnw clean package`
|
|
|
|
or run the test in your favorite IDE.
