Improve extensibility of TestContext bootstrapping & context caching
These commits include numerous refactorings and enhancements to the
bootstrapping and context caching mechanisms in the Spring TestContext
Framework.
Issue: SPR-12683
- 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().

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.

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 change adds support for broadcasting messages with unresolved
user destinations so that other servers can try to resolve it.
That enables sending messages to users who may be connected to a
different server.
Issue: SPR-11620
Prior to this commit, ClassLevelDirtiesContextTests existed for
verifying the expected behavior of @DirtiesContext declared at the
class level in conjunction with JUnit and SpringJUnit4ClassRunner.
This commit introduces analogous tests for TestNG in the new
ClassLevelDirtiesContextTestNGTests class.
Furthermore, ContextCacheTestUtils and TrackingTestNGTestListener have
been introduced to reduce code duplication across the test suite.
Issue: SPR-12918
The attributes of @JmsListener allows to specify the reference to a key
in the Environment but @SendTo did not.
This commit fixes this inconsistency so that response destinations are
now also externally configurable.
Issue: SPR-12899
Previously, the "pubSubDomain" drove the resolution of both the
destination of the listener and the default response destination.
A new "replyPubSubDomain" attribute has been added on the base listener
and can be used to listen on a topic and reply to a queue (or vice
versa). The attribute is exposed via the "response-destination-type" XML
attribute on the listener container element. It is also available on the
JmsListenerContainerFactory for use with the @JmsListener infrastructure.
Issue: SPR-12911
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
This commit improves the documentation for ScriptUtils by explicitly
mentioning that a JDBC Connection supplied to the one of the
executeSqlScript() methods will not be released automatically.
Issue: SPR-12908
The onFailure callback and future.get() occur in different threads so
this change adds a latch to ensure we have both before asserting.
Issue: SPR-12887
AbstractHttpMessageConverter now tries to call getDefaultContentType
with the actual value to be converted to see if that will result in
a more concrete mediat type than application/octet-stream.
Issue: SPR-12894
The use of RedirectAttributes was documented in four places in the
reference documentation. This commit merges some of the places and links
properly between them.
Issue: SPR-12759
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.
