java.lang.IllegalStateException

Duplicate mock definition [MockDefinition@1b68b9a4 name = '', classToMock = IdentityProvider, extraInterfaces = set[[empty]], answer = RETURNS_DEFAULTS, serializable = false, reset = AFTER]

If you're using boot 1.4.x you need to modify the @springBootTest annotation to @SpringBootTest(classes = DataFlowServerConfiguration.class). 1.3.8 doesn't have this problem as well.

Spring Boot 1.4 changed their annotation system a little. Try using the @SpringBootApplication annotation for better results.
