+== PulsarTestContainerSupport
+
+The `org.springframework.pulsar.test.support.PulsarTestContainerSupport` interface provides a static Pulsar Testcontainer.
+When using Junit Jupiter, the container is automatically started once per test class via `@BeforeAll` annotation.
+
+The following example shows how you can use the container support in a `@SpringBootTest` in conjunction with the previously mentioned `PulsarConsumerTestUtil`.

 WARNING: If you were previously catching or rethrowing `PulsarClientException` just to appease the compiler and were not actually handling the exception, you can simply remove your `catch` or `throws` clause.
 If you were actually handling the exception then you will need to replace `PulsarClientException` with `PulsarException` in your catch clause.
