 These tests will **not** work if run in the same phase as `@QuarkusTest` as Quarkus has not yet created the final artifact.

+[NOTE]
+====
+As is the case with `@QuarkusTest`, logging statements can be added to the test method of a `@QuarkusIntegrationTest` as well. However, the logging configuration for the application is currently not taken into account in this case. Please open an issue if this feature is important.
