Unit Testing

The repository comes preconfigured with the following test dependencies to allow the quick authoring of unit tests:

• JUnit5 framework for writing unit tests.
• Mockito for quickly mocking types and verifying invocations.
• Hamcrest for more descriptive assertions.
• Guava TestLib which contains many useful testing utilities.
• Log4J 2.x with SLF4J bindings, to allow test code to log.

In addition, each microservice added to the repository comes with a bare-bones TopologyBuilderTest class, which can be enhanced to test the service’s Kafka Streams topology, making use of:

• Kafka Streams test utils
• Creek Kafka Streams test util
