**Springfox**: upgrade 2.8.0 -> 2.9.0 **SpringBoot**: 1.5.12 **Spock**: 1.1-groovy-2.4-rc-4 **Issue**: when trying to run `@SpringBootTest` it fails with a message ``` Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test ``` I have my `Application` class annotated with `@SpringBootApplication` and placed in root package hierarchy, so it's not the cause. Also, of course, it worked before just fine - reverting back to 2.8.0 fixes the problem. Also, adding `classes = Application.class` to `@SpringBootTest` also fixes the problem. Seems like #2438 and #2388 may be related? Any hints? **Full stacktrace:** ``` 2018-05-24 12:00:53.023 INFO --- [ main] .b.t.c.SpringBootTestContextBootstrapper : Neither @ContextConfiguration nor @ContextHierarchy found for test class [pl.airly.dao.InstallationCalibrationDaoTest], using SpringBootContextLoader 2018-05-24 12:00:53.241 INFO --- [ main] o.s.t.c.support.AbstractContextLoader : Could not detect default resource locations for test class [pl.airly.dao.InstallationCalibrationDaoTest]: no resource found for suffixes {-context.xml, Context.groovy}. 2018-05-24 12:00:53.252 INFO --- [ main] t.c.s.AnnotationConfigContextLoaderUtils : Could not detect default configuration classes for test class [pl.airly.dao.InstallationCalibrationDaoTest]: InstallationCalibrationDaoTest does not declare any static, non-private, non-final, nested classes annotated with @Configuration. java.lang.IllegalStateException: Unable to find a @SpringBootConfiguration, you need to use @ContextConfiguration or @SpringBootTest(classes=...) with your test at org.springframework.util.Assert.state(Assert.java:70) at org.springframework.boot.test.context.SpringBootTestContextBootstrapper.getOrFindConfigurationClasses(SpringBootTestContextBootstrapper.java:202) at org.springframework.boot.test.context.SpringBootTestContextBootstrapper.processMergedContextConfiguration(SpringBootTestContextBootstrapper.java:137) at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildMergedContextConfiguration(AbstractTestContextBootstrapper.java:397) at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildDefaultMergedContextConfiguration(AbstractTestContextBootstrapper.java:311) at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildMergedContextConfiguration(AbstractTestContextBootstrapper.java:265) at org.springframework.test.context.support.AbstractTestContextBootstrapper.buildTestContext(AbstractTestContextBootstrapper.java:105) at org.springframework.boot.test.context.SpringBootTestContextBootstrapper.buildTestContext(SpringBootTestContextBootstrapper.java:82) at org.springframework.test.context.TestContextManager.<init>(TestContextManager.java:120) at org.springframework.test.context.TestContextManager.<init>(TestContextManager.java:105) at org.spockframework.spring.SpringTestContextManager.<init>(SpringTestContextManager.java:35) at org.spockframework.spring.SpringExtension.visitSpec(SpringExtension.java:65) at org.spockframework.runtime.ExtensionRunner.runGlobalExtensions(ExtensionRunner.java:46) at org.spockframework.runtime.ExtensionRunner.run(ExtensionRunner.java:40) at org.spockframework.runtime.Sputnik.runExtensionsIfNecessary(Sputnik.java:88) at org.spockframework.runtime.Sputnik.getDescription(Sputnik.java:55) at com.intellij.junit4.JUnit4IdeaTestRunner.getDescription(JUnit4IdeaTestRunner.java:78) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:50) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) Process finished with exit code -2 Empty test suite. ```
