Support test annotations on interfaces [SPR-14184]

[spring-projects-issues]

Sam Brannen opened SPR-14184 and commented

Status Quo

Prior to Java 8 it never really made much sense to author integration tests using interfaces. Consequently, the Spring TestContext Framework has never supported finding test-related annotations on interfaces in its search algorithms.

However, Java 8's support for interface default methods introduces new testing use cases for which it makes sense to declare test configuration (e.g., @ContextConfiguration, etc.) on an interface containing default methods instead of on an abstract base class.

Deliverables

For each of the following annotations, implement and test support for declaration on test interfaces.

1. @ActiveProfiles
   • see ActiveProfilesInterfaceTests
2. @BootstrapWith
   • see BootstrapWithInterfaceTests
3. @ContextConfiguration
   • see ContextConfigurationInterfaceTests
4. @ContextHierarchy
   • see ContextHierarchyInterfaceTests
5. @WebAppConfiguration
   • see WebAppConfigurationInterfaceTests
6. @DirtiesContext
   • see DirtiesContextInterfaceTests
7. @TestExecutionListeners
   • see customListenersDeclaredOnInterface() in TestExecutionListenersTests
8. @TestPropertySource
   • see TestPropertySourceInterfaceTests
9. @Sql and @SqlGroup
   • see Support @Sql annotations on test interfaces #18827
10. @SqlConfig
    • see SqlConfigInterfaceTests
11. @Commit
    • see TransactionalTestExecutionListenerTests
12. @Rollback
    • see TransactionalTestExecutionListenerTests
13. @IfProfileValue
    • see DisabledAnnotatedSingleValueOnTestInterface in ProfileValueUtilsTests
14. @ProfileValueSourceConfiguration
    • see EnabledWithCustomProfileValueSourceOnTestInterface in ProfileValueUtilsTests
