Prior to this commit, some same-page links in our Antora-based docs
were written using the `xref:` macro, which Antora resolves as a
cross-page reference. However, a same-page target can be misread as a
page reference and break the site build (as nearly happened in
gh-37152), whereas `<<id,text>>` only ever resolves against the current
page's own anchors.
To address that inconsistency and avoid potential future bugs (broken
links), this commit converts all such same-page `xref:` links to
`<<id,text>>`, leaving genuine cross-page `xref:` links are unaffected.

A user reported confusion between two distinct uses of "wraps" in the
AOP proxy documentation for Bean Overrides: the sense in which a
Mockito spy wraps the original bean instance it was created from, and
the sense in which a Spring AOP proxy wraps the spy in the actual
object graph.
To address that, this commit adds two small diagrams to the general
"Bean Overrides and Spring AOP Proxies" section, illustrating, from a
caller's perspective, the shape of the bean for the
REPLACE/REPLACE_OR_CREATE strategy (no proxy at all) versus the WRAP
strategy (an AOP proxy still created, now wrapping the override
instance instead of the original bean). Both diagrams use the same
generic "override instance" label, since the section is not specific to
Mockito; a Mockito spy created by @MockitoSpyBean is mentioned only as
an example.
The accompanying text is revised to reserve "wraps" for the AOP proxy
relationship and to explicitly call out that a Mockito spy's
relationship to its original bean instance is a separate concern from
AOP proxy nesting.
The @MockitoSpyBean-specific strategy paragraph in the
@MockitoBean/@MockitoSpyBean documentation has also been revised
similarly, and now points to the new diagram.

This commit documents how the Bean Override support in the TestContext
framework interacts with Spring AOP proxies created for annotations
such as @Transactional, @Cacheable, and @Retryable.
The new "Bean Overrides and Spring AOP Proxies" section in the general
Bean Overriding documentation explains that overrides using the WRAP
strategy (such as @MockitoSpyBean) end up as the target of any AOP
proxy subsequently created for the original bean; whereas, overrides
using the REPLACE or REPLACE_OR_CREATE strategy (such as @TestBean,
@MockitoBean) bypass the container's bean post-processing entirely and
therefore carry no AOP advice at all.
The new "@MockitoSpyBean and Spring AOP Proxies" section documents the
resulting stubbing and verification semantics. Verification via
Mockito's verify() API works transparently regardless of whether it is
invoked on the proxy or on the spy. Stubbing via doReturn(...)/doThrow(...)
is safe for stateless advice such as @Retryable, but can silently
corrupt the spy's configured answers for stateful or memoizing advice
such as @Cacheable, since the invocation used to declare a stub is
intercepted by Mockito before it reaches the spy and returns an empty
value that such advice may then cache.
AopTestUtils.getUltimateTargetObject(...) is documented as the way to
stub directly against the spy in that case.
The same section also documents how to disable the AOP advice for a
test altogether while leaving it in place in production code – for
example, binding a @Retryable attribute to a property placeholder
overridden via @TestPropertySource, or replacing the CacheManager with
a NoOpCacheManager via @TestBean.
Brief cross-referencing notes have also been added to the @TestBean
documentation and to the existing AopTestUtils description in the
"General Testing Utilities" section, to avoid duplicating the
explanation across pages.
In addition, the Javadoc for @MockitoSpyBean now contains a concise
WARNING summarizing these AOP proxy implications and linking to the new
reference documentation section for details.

The Spring TestContext Framework does not honor the
`spring.profiles.active` system property when determining
active profiles for a test class if @ActiveProfiles is
used.
This commit documents that behavior in the @ActiveProfiles
and DefaultActiveProfilesResolver Javadoc, as well as in
the reference manual. A SystemPropertyActiveProfilesResolver
example is also added showing how to allow
`spring.profiles.active` to override @ActiveProfiles.

Prior to this commit, @MockitoBean and @MockitoSpyBean could be
declared on fields or at the type level (on test classes and test
interfaces), but not on constructor parameters. Consequently, a test
class could not use constructor injection for bean overrides.
To address that, this commit introduces support for @MockitoBean and
@MockitoSpyBean on constructor parameters in JUnit Jupiter test
classes. Specifically, the Bean Override infrastructure has been
overhauled to support constructor parameters as declaration sites and
injection points alongside fields, and the SpringExtension now
recognizes composed @BeanOverride annotations on constructor
parameters in supportsParameter() and resolves them properly in
resolveParameter(). Note, however, that this support has not been
introduced for @TestBean.
For example, the following which uses field injection:
@SpringJUnitConfig(TestConfig.class)
class BeanOverrideTests {
@MockitoBean
CustomService customService;
// tests...
}
Can now be rewritten to use constructor injection:
@SpringJUnitConfig(TestConfig.class)
class BeanOverrideTests {
private final CustomService customService;
BeanOverrideTests(@MockitoBean CustomService customService) {
this.customService = customService;
}
// tests...
}
With Kotlin this can be achieved even more succinctly via a compact
constructor declaration:
@SpringJUnitConfig(TestConfig::class)
class BeanOverrideTests(@MockitoBean val customService: CustomService) {
// tests...
}
Of course, if one is a fan of so-called "test records", that can also
be achieved succinctly with a Java record:
@SpringJUnitConfig(TestConfig.class)
record BeanOverrideTests(@MockitoBean CustomService customService) {
// tests...
}

Prior to this commit, the extension context scope used by the
SpringExtension defaulted to test-method scoped and could only be
changed on a per-class basis via the @SpringExtensionConfig
annotation. However, having to annotate each affected test class is
cumbersome for developers who wish to use test-class scoped extension
context semantics across their code base.
To address that, this commit introduces support for configuring the
global default extension context scope for the SpringExtension via
Spring properties or JUnit properties.
Specifically, this commit introduces a
`spring.test.extension.context.scope` property that can be set via the
SpringProperties mechanism or via a JUnit Platform configuration
parameter.
See gh-35697
Closes gh-36460
This commit also updates the Javadoc for the SpringExtension and
@SpringExtensionConfig to point out that the SpringExtension always
uses a test-class scoped ExtensionContext if
@TestInstance(Lifecycle.PER_CLASS) semantics are in effect.

In commit 9711db787e, we introduced support for disabling test
application context pausing via a Spring property or JVM system
property, as follows.
-Dspring.test.context.cache.pause=never
However, users may actually be interested in keeping the pausing
feature enabled if contexts are not paused unnecessarily.
To address that, this commit introduces a new
PauseMode.ON_CONTEXT_SWITCH enum constant which is now used by default
in the DefaultContextCache.
With this new pause mode, an unused application context will no longer
be paused immediately. Instead, an unused application context will be
paused lazily the first time a different context is retrieved from or
stored in the ContextCache. This effectively means that an unused
context will not be paused at all if the next test class uses the same
context.
Although ON_CONTEXT_SWITCH is the now the default pause mode, users
still have the option to enable context pausing for all usage scenarios
(not only context switches) by setting the Spring property or JVM
system property to ALWAYS (case insensitive) — for example:
-Dspring.test.context.cache.pause=always
This commit also introduces a dedicated "Context Pausing" section in
the reference manual.

Spring Framework 7.0 introduced support for pausing inactive
application contexts between test classes and restarting them once they
are needed again. If pausing and restarting are fast, this feature does
not have a negative impact on test suites.
However, if the pausing or restarting of certain Lifecycle components
in the application context is slow, that can have a negative impact on
the duration of the overall test suite.
In gh-36044, we hope to find a way to avoid unnecessarily pausing an
application context after a test class if the same context is used by
the next test class that is run. That should help reduce the risk of a
negative impact caused by the pause/restart feature; however, for
certain scenarios that may not be enough. In light of that, this commit
introduces a mechanism for completely disabling the pausing feature via
a Spring property or JVM system property, as follows.
-Dspring.test.context.cache.pause=never

Although @PersistenceContext and @PersistenceUnit are still not
supported in tests running in AOT mode, as of Spring Framework 7.0,
developers can inject an EntityManager or EntityManagerFactory into
tests using @Autowired instead of @PersistenceContext and
@PersistenceUnit, respectively.

Prior to this commit, the BeanOverrideBeanFactoryPostProcessor rejected
any attempt to override a non-singleton bean; however, due to interest
from the community, we have decided to provide support for overriding
non-singleton beans via the Bean Override mechanism — for example, when
using @MockitoBean, @MockitoSpyBean, and @TestBean.
With this commit, we now support Bean Overrides for non-singletons: for
standard JVM runtimes as well as AOT processing and AOT runtimes. This
commit also documents that non-singletons will effectively be converted
to singletons when overridden and logs a warning similar to the
following.
WARN: BeanOverrideBeanFactoryPostProcessor - Converting 'prototype' scoped bean definition 'myBean' to a singleton.

Since the introduction of the Spring TestContext Framework in 2007,
application contexts have always been stored in the context cache in a
"running" state. However, leaving a context running means that
components in the context may continue to run in the background. For
example, JMS listeners may continue to consume messages from a queue;
scheduled tasks may continue to perform active work, etc.; and this can
lead to issues within a test suite.
To address such issues, this commit introduces built-in support for
pausing application contexts when they are not in use and restarting
them if they are needed again.
Specifically, the TestContextManager now marks a test's application
context as "unused" after execution of the test class has ended, and
the underlying ContextCache then "stops" the application context if no
other test class is currently using the context. When a
TestExecutionListener later attempts to obtain a paused application
context -- for example, for a subsequent test class that shares the
same application context -- the ContextCache ensures that context is
restarted before returning it.
