This commit updates code that previously used getAnnotationAttributes()
in AnnotatedElementUtils to use findAnnotationAttributes(), where
appropriate.
Issue: SPR-12738
This commit introduces support in the spring-test module for obtaining a
reference to the underlying target object hidden behind one or more
proxies.
Specifically this commit introduces AopTestUtils with two methods:
- getTargetObject(Object)
- getUltimateTargetObject(Object)
Issue: SPR-13005
Prior to this commit it was possible for two @BootstrapWith annotations
to be 'present' on a test class -- for example, via competing custom
composed annotations. However, only one of the annotations will ever be
used to bootstrap the TestContext Framework. Thus, in such scenarios
one of the annotations will be silently ignored.
This commit introduces a check for such scenarios. BootstrapUtils'
resolveTestContextBootstrapper() method now throws an
IllegalStateException if more than one @BootstrapWith annotation is
'present' on a given test class.
Issue: SPR-12602
Previously MockHttpServletRequestBuilder merge method would append the
parent's (default) RequestPostProcessor implementations to the end. This
means that the default RequestPostProcessor implementations would override
values set by previous RequestPostProcessor implementations.
This commit ensures that the default RequestPostProcessor are preformed
first so that additional RequestPostProcessor implementations override
the defaults.
Issue: SPR-12945
This commit introduces support for finding annotations on abstract,
bridge, and interface methods in AnnotatedElementUtils.
- Introduced dedicated findAnnotationAttributes() methods in
AnnotatedElementUtils that provide first-class support for
processing methods, class hierarchies, interfaces, bridge methods,
etc.
- Introduced find/get search algorithm dichotomy in
AnnotatedElementUtils which is visible in the public API as well as
in the internal implementation. This was necessary in order to
maintain backwards compatibility with the existing API (even though
it was undocumented).
- Reverted all recent changes made to the "get semantics" search
algorithm in AnnotatedElementUtils in order to ensure backwards
compatibility, and reverted recent changes to
JtaTransactionAnnotationParser and SpringTransactionAnnotationParser
accordingly.
- Documented internal AnnotatedElementUtils.Processor<T> interface.
- Enabled failing tests and introduced
findAnnotationAttributesFromBridgeMethod() test in
AnnotatedElementUtilsTests.
- Refactored ApplicationListenerMethodAdapter.getCondition() and
enabled failing test in TransactionalEventListenerTests.
- AnnotationUtils.isInterfaceWithAnnotatedMethods() is now package
private.
Issue: SPR-12738, SPR-11514, SPR-11598
Prior to this commit, AnnotationAttributes retrieved from
MetaAnnotationUtils's AnnotationDescriptor could contain attributes
from the wrong annotation if an inherited annotation shadowed a locally
declared composed annotation.
This commit addresses this issue by invoking the new
getAnnotationAttributes() method in AnnotatedElementUtils that provides
a flag to control whether superclasses should be searched -- which
coincidentally processes local annotations before searching the class
hierarchy.

Since the ContextCache is now a published SPI, it and its collaborators
have been moved to a dedicated 'org.sfw.test.context.cache' subpackage.
Issue: SPR-12683
This commit adds an assertion to DefaultTestContext's
getApplicationContext() method to ensure that a context loaded by the
Spring TestContext Framework (TCF) or retrieved from the ContextCache
is still active. This extra check helps to avoid situations where
developers manually close a cached context instead of relying on the
@DirtiesContext support.
Issue: SPR-12932
The changes made in 0cb22fc8f3 would
result in contexts not being properly closed if evicted from the
ConcurrentReferenceHashMap by the Garbage Collector.
This commit reverts those changes and returns to using standard
ConcurrentHashMaps for the time being.
Issue: SPR-7687
- DefaultBootstrapContext and DefaultCacheAwareContextLoaderDelegate
are now public classes in the 'support' subpackage.
- Introduced getCacheAwareContextLoaderDelegate() in
AbstractTestContextBootstrapper as an extension point for configuring
custom ContextCache support.
- Introduced reflection-based createBootstrapContext() utility method
in BootstrapUtils; TestContextManager now delegates to BootstrapUtils
in order to avoid package cycles.
- Introduced logStatistics() method in the ContextCache API and defined
statistics logging category as a constant.
- DefaultCacheAwareContextLoaderDelegate now delegates to
ContextCache.logStatistics().
Issue: SPR-12683
This commit moves the responsibility of building a TestContext from the
TestContextManager to a TestContextBootstrapper.
In addition, DefaultTestContext is now a public class residing in the
"support" subpackage.
Issue: SPR-12683
Prior to this commit, the ContextCache in the Spring TestContext
Framework (TCF) cached ApplicationContexts in a ConcurrentHashMap using
strong references. This practice can occasionally lead to
OutOfMemoryErrors when running a large number of tests in a test suite
with varying context configuration since the context cache becomes
overpopulated over time.
This commit addresses this issue by using Spring's
ConcurrentReferenceHashMap which uses SoftReferences for both the keys
(i.e., MergedContextConfiguration instances) and values (i.e.,
ApplicationContexts) stored in the map that backs the ContextCache.
Issue: SPR-7687
This commit increases the extensibility of
AbstractTestContextBootstrapper by making the resolveContextLoader()
and resolveExplicitContextLoaderClass() methods protected instead of
private.
Furthermore, resolveContextLoader() now throws an IllegalStateException
if getDefaultContextLoaderClass() returns null.
Issue: SPR-12682
Prior to this commit it was possible to set or get a static field using
ReflectionTestUtils but only if an instance of the target class was
available.
This commit introduces dedicated support for setting and getting static
fields in ReflectionTestUtils when only the target class is available.
Furthermore, this commit increases the robustness of
ReflectionTestUtilsTests regarding expected exceptions and simplifies
the Javadoc for ReflectionTestUtils.
Issue: SPR-6792
Prior to this commit, @DirtiesContext could only be used to close a
test ApplicationContext after an entire test class or after a test
method; however, there are some use cases for which it would be
beneficial to close a test ApplicationContext before a given test class
or test method -- for example, if some rogue (i.e., yet to be
determined) test within a large test suite has corrupted the original
configuration for the ApplicationContext.
This commit provides a solution to such testing challenges by
introducing the following modes for @DirtiesContext.
- MethodMode.BEFORE_METHOD: configured via the new methodMode attribute
- ClassMode.BEFORE_CLASS and ClassMode.BEFORE_EACH_TEST_METHOD: both
configured via the existing classMode attribute
Issue: SPR-12429
This commit simplifies the implementations of loadBeanDefinitions() in
GenericGroovyXmlContextLoader and GenericGroovyXmlWebContextLoader.
Due to the recent bug fix for GroovyBeanDefinitionReader regarding full
support for XML config files, these Groovy context loaders can now
simply use a GroovyBeanDefinitionReader instead of a
GroovyBeanDefinitionReader plus an XmlBeanDefinitionReader.
Issue: SPR-12769
Prior to this commit, it was impossible to use all features of XML
configuration (e.g., the <qualifier> tag) in web-based integration
tests (loaded using @WebAppConfiguration, @ContextConfiguration, etc.)
if the Groovy library was on the classpath. The reason is that the
GroovyBeanDefinitionReader used internally by
GenericGroovyXmlWebContextLoader disables XML validation for its
internal XmlBeanDefinitionReader, and this prevents some XML
configuration features from working properly. For example, the default
value for the 'type' attribute (defined in the spring-beans XSD) of the
<qualifier> tag gets ignored, resulting in an exception when the
application context is loaded.
This commit addresses this issue by refactoring the implementation of
loadBeanDefinitions() in GenericGroovyXmlWebContextLoader to use an
XmlBeanDefinitionReader or GroovyBeanDefinitionReader depending on the
file extension of the resource location from which bean definitions
should be loaded. This aligns the functionality of
GenericGroovyXmlWebContextLoader with the existing functionality of
GenericGroovyXmlContextLoader.
Issue: SPR-12768
- Added assertions for pre-conditions on method arguments for all
public utility methods.
- Introduced additional tests in TestPropertySourceUtilsTests to verify
the new pre-conditions.
- Introduced INLINED_PROPERTIES_PROPERTY_SOURCE_NAME constant for the
name of the MapPropertySource created from inlined properties; the
name therefore no longer contains the inlined properties, but the
original values of the inlined properties can now be logged at debug
level.
- Simplified tests in InlinedPropertiesTestPropertySourceTests.
Issue: SPR-12721
Spring Framework 4.1 introduced support for @TestPropertySource;
however, the utilities used to parse inlined properties and add test
property sources to the environment are currently private which
prevents reuse by third-party frameworks like Spring Boot.
This commit addresses this issue by making such utilities public.
- TestPropertySourceUtils is now a public class.
- Various utility methods in TestPropertySourceUtils have been made
public.
- addResourcePropertySourcesToEnvironment() has been renamed to
addPropertiesFilesToEnvironment().
- extractEnvironmentProperties() has been renamed to
convertInlinedPropertiesToMap().
- All public methods in TestPropertySourceUtils are now fully
documented.
Issue: SPR-12721
The initial implementation for adding inlined properties configured via
@TestPropertySource to the context's environment did not preserve the
order in which the properties were physically declared. This makes
@TestPropertySource a poor testing facility for mimicking the
production environment's configuration if the property source mechanism
used in production preserves ordering of property names -- which is the
case for YAML-based property sources used in Spring Boot, Spring Yarn,
etc.
This commit addresses this issue by ensuring that the ordering of
inlined properties declared via @TestPropertySource is preserved.
Specifically, the original functionality has been refactored. extracted
from AbstractContextLoader, and moved to TestPropertySourceUtils where
it may later be made public for general purpose use in other frameworks.
Issue: SPR-12710
Add support for annotation-based event listeners. Enabled automatically
when using Java configuration or can be enabled explicitly via the
regular <context:annotation-driven/> XML element. Detect methods of
managed beans annotated with @EventListener, either directly or through
a meta-annotation.
Annotated methods must define the event type they listen to as a single
parameter argument. Events are automatically filtered out according to
the method signature. When additional runtime filtering is required, one
can specify the `condition` attribute of the annotation that defines a
SpEL expression that should match to actually invoke the method for a
particular event. The root context exposes the actual `event`
(`#root.event`) and method arguments (`#root.args`). Individual method
arguments are also exposed via either the `a` or `p` alias (`#a0` refers
to the first method argument). Finally, methods arguments are exposed via
their names if that information can be discovered.
Events can be either an ApplicationEvent or any arbitrary payload. Such
payload is wrapped automatically in a PayloadApplicationEvent and managed
explicitly internally. As a result, users can now publish and listen
for arbitrary objects.
If an annotated method has a return value, an non null result is actually
published as a new event, something like:
@EventListener
public FooEvent handle(BarEvent event) { ... }
Events can be handled in an aynchronous manner by adding `@Async` to the
event method declaration and enabling such infrastructure. Events can
also be ordered by adding an `@Order` annotation to the event method.
Issue: SPR-11622
Spring Framework 4.0 introduced support for using test-related
annotations as meta-annotations in the Spring TestContext Framework
(TCF) in order to create custom composed annotations within a test
suite; however, the detection of default @Configuration classes in test
classes was not updated to search for @Configuration declared as a
meta-annotation. Specifically, AnnotationConfigContextLoaderUtils
invokes Class.isAnnotated() which only searches for annotations
declared directly on the class in question.
This commit addresses this issue by refactoring the
isDefaultConfigurationClassCandidate() method in
AnnotationConfigContextLoaderUtils so that it uses
AnnotationUtils.findAnnotation() instead of Class.isAnnotated() for
detecting the presence of the @Configuration annotation, either
directly or as a meta-annotation.
Issue: SPR-12659
Various parts of the reference manual as well as the Javadoc for
AnnotationConfigContextLoaderUtils improperly refer to "static inner
classes" even though this terminology does not exist in Java. The Java
Language Specification explicitly refers to such classes as "static
nested classes." An "inner class" must be non-static by definition.
In order to allow DefaultActiveProfilesResolver to be reused (e.g., via
extension or delegation), the check which asserts that the 'resolver'
attribute of @ActiveProfiles is not set to a customer resolver class
has been removed.
Issue: SPR-12611
JUnit 4.9 introduced a regression in BlockJUnit4ClassRunner.runChild()
such that exceptions thrown from methodBlock() cause the current test
execution to abort immediately. As a result, the failing test method is
unrooted, and subsequent test methods are never invoked. Furthermore,
RunListeners registered with JUnit are not properly notified.
In conjunction with SPR-11908, SpringJUnit4ClassRunner was updated to
use the aforementioned changes to BlockJUnit4ClassRunner.runChild().
Consequently, SpringJUnit4ClassRunner now suffers from the same
regression.
This commit addresses this issue by ensuring that any exceptions thrown
during the invocation of methodBlock() are properly wrapped in a JUnit
Fail Statement.
