The JsonConverterDelegate interface replaces usages of
HttpMessageContentConverter to provides the flexibility to use either
message converters or WebFlux codecs.
HttpMessageContentConverter is deprecated, and replaced with a package
private copy (DefaultJsonConverterDelegate) in the
org.springframework.test.json package that is accessible through
a static method on JsonConverterDelegate.

Prior to this commit, an attempt to use @MockitoSpyBean to spy on a
scoped proxy configured with
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS) resulted in an
exception thrown by Mockito when the spy was stubbed. The exception
message stated "Failed to unwrap proxied object" but did not provide
any further insight or context for the user.
The reason is that ScopedProxyFactoryBean is used to create such a
scoped proxy, which uses a SimpleBeanTargetSource, which is not a
static TargetSource. Consequently,
SpringMockResolver.getUltimateTargetObject(Object) is not able to
unwrap the proxy.
In order to improve diagnostics for users, this commit eagerly detects
an attempt to spy on a scoped proxy and throws an exception with a
meaningful message. The following is an example, trimmed stack trace
from the test suite.
org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'myScopedProxy': Post-processing of
FactoryBean's singleton object failed
...
Caused by: java.lang.IllegalStateException:
@MockitoSpyBean cannot be applied to bean 'myScopedProxy', because
it is a Spring AOP proxy with a non-static TargetSource. Perhaps you
have attempted to spy on a scoped proxy, which is not supported.

This commit upgrades our test suite to use JUnit 6.0.1 and removes the
systemProperty("junit.platform.discovery.issue.severity.critical", "WARNING")
configuration from spring-test.gradle, so that all discovery issues will
fail the build for the spring-test module as well.
In addition, this commit prevents potential AOT test scanning failures
for JUnit 4 tests by setting the
"junit.vintage.discovery.issue.reporting.enabled" configuration
parameter to "false" in TestClassScanner.

As of Spring Framework 6.2.13, we support JUnit Jupiter 5.12's
ExtensionContextScope.TEST_METHOD behavior in the SpringExtension and
the BeanOverrideTestExecutionListener; however, users can only benefit
from that if they explicitly set the following configuration parameter
for their entire test suite, which may have adverse effects on other
third-party JUnit Jupiter extensions.
junit.jupiter.extensions.testinstantiation.extensioncontextscope.default=test_method
For Spring Framework 7.0, in order to support dependency injection into
test class constructors and fields in @Nested test class hierarchies
from the same ApplicationContext that is already used to perform
dependency injection into lifecycle and test methods (@BeforeEach,
@AfterEach, @Test, etc.), we have decided to configure the
SpringExtension to use ExtensionContextScope.TEST_METHOD by default. In
addition, we have decided to provide a mechanism for users to switch
back to the legacy "test-class scoped ExtensionContext" behavior in
case third-party TestExecutionListener implementations are not yet
compatible with test-method scoped ExtensionContext and TestContext
semantics.
This commit achieves the above goals as follows.
- A new @SpringExtensionConfig annotation has been introduced, which
allows developers to configure the effective ExtensionContext scope
used by the SpringExtension.
- The SpringExtension now overrides
getTestInstantiationExtensionContextScope() to return
ExtensionContextScope.TEST_METHOD.
- The postProcessTestInstance() and resolveParameter() methods in the
SpringExtension now find the properly scoped ExtensionContext for the
supplied test class, based on whether the @Nested test class
hierarchy is annotated with
@SpringExtensionConfig(useTestClassScopedExtensionContext = true).

Although gh-35680 introduced support for JUnit Jupiter's TEST_METHOD
ExtensionContextScope in the SpringExtension and
BeanOverrideTestExecutionListener, those were internal changes that are
not directly visible by TestExecutionListener authors.
However, in order to be compatible with a test-method scoped
TestContext (which takes its values from the current Jupiter
ExtensionContext), existing third-party TestExecutionListener
implementations may need to be modified similar to how
BeanOverrideTestExecutionListener was modified in commit d24a31d469.
To raise awareness of how to deal with such issues, this commit
documents test-method TestContext semantics for TestExecutionListener
authors.

Historically, @Autowired fields in an enclosing class of a @Nested
test class have been injected from the ApplicationContext for the
enclosing class. If the enclosing test class and @Nested test class
share the same ApplicationContext configuration, things work as
developers expect. However, if the enclosing class and @Nested test
class have different ApplicationContexts, that can lead to
difficult-to-debug scenarios. For example, a bean injected into the
enclosing test class will not participate in a test-managed transaction
in the @Nested test class (see gh-34576).
JUnit Jupiter 5.12 introduced a new ExtensionContextScope feature which
allows the SpringExtension to behave the same for @Autowired fields as
it already does for @Autowired arguments in lifecycle and test
methods. Specifically, if a developer sets the ExtensionContextScope to
TEST_METHOD — for example, by configuring the following configuration
parameter as a JVM system property or in a `junit-platform.properties`
file — the SpringExtension already supports dependency injection from
the current, @Nested ApplicationContext in @Autowired fields in an
enclosing class of the @Nested test class.
junit.jupiter.extensions.testinstantiation.extensioncontextscope.default=test_method
However, there are two scenarios that fail as of Spring Framework
6.2.12.
1. @TestConstructor configuration in @Nested class hierarchies.
2. Field injection for bean overrides (such as @MockitoBean) in
@Nested class hierarchies.
Commit 82c34f7b51 fixed the SpringExtension to support scenario #2
above.
To fix scenario #1, this commit revises
BeanOverrideTestExecutionListener's injectField() implementation to
look up the fields to inject for the "current test instance" instead of
for the "current test class".
This commit also introduces tests for both scenarios.

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.
