Prior to this commit, the Spring TestContext Framework (TCF) supported
the use of test-related annotations as meta-annotations for composing
custom test stereotype annotations; however, attributes in custom
stereotypes could not be used to override meta-annotation attributes.
This commit addresses this by allowing attributes from the following
annotations (when used as meta-annotations) to be overridden in custom
stereotypes.
- @ContextConfiguration
- @ActiveProfiles
- @DirtiesContext
- @TransactionConfiguration
- @Timed
- @TestExecutionListeners
This support depends on functionality provided by
AnnotatedElementUtils. See the 'Notes' below for further details and
ramifications.
Notes:
- AnnotatedElementUtils does not support overrides for the 'value'
attribute of an annotation. It is therefore not possible or not
feasible to support meta-annotation attribute overrides for some
test-related annotations.
- @ContextHierarchy, @WebAppConfiguration, @Rollback, @Repeat, and
@ProfileValueSourceConfiguration define single 'value' attributes
which cannot be overridden via Spring's meta-annotation attribute
support.
- Although @IfProfileValue has 'values' and 'name' attributes, the
typical usage scenario involves the 'value' attribute which is not
supported for meta-annotation attribute overrides. Furthermore,
'name' and 'values' are so generic that it is deemed unfeasible to
provide meta-annotation attribute override support for these.
- @BeforeTransaction and @AfterTransaction do not define any attributes
that can be overridden.
- Support for meta-annotation attribute overrides for @Transactional is
provided indirectly via SpringTransactionAnnotationParser.
Implementation Details:
- MetaAnnotationUtils.AnnotationDescriptor now provides access to the
AnnotationAttributes for the described annotation.
- MetaAnnotationUtils.AnnotationDescriptor now provides access to the
root declaring class as well as the declaring class.
- ContextLoaderUtils now retrieves AnnotationAttributes from
AnnotationDescriptor to look up annotation attributes for
@ContextConfiguration and @ActiveProfiles.
- ContextConfigurationAttributes now provides a constructor to have its
attributes sourced from an instance of AnnotationAttributes.
- ContextLoaderUtils.resolveContextHierarchyAttributes() now throws an
IllegalStateException if no class in the class hierarchy declares
@ContextHierarchy.
- TransactionalTestExecutionListener now uses AnnotatedElementUtils to
look up annotation attributes for @TransactionConfiguration.
- Implemented missing unit tests for @Rollback resolution in
TransactionalTestExecutionListener.
- SpringJUnit4ClassRunner now uses AnnotatedElementUtils to look up
annotation attributes for @Timed.
- TestContextManager now retrieves AnnotationAttributes from
AnnotationDescriptor to look up annotation attributes for
@TestExecutionListeners.
- DirtiesContextTestExecutionListener now uses AnnotatedElementUtils to
look up annotation attributes for @DirtiesContext.
