To make an analogy to read phenomena for transactional databases, this
commit effectively fixes the "Phantom Read" problem for Bean Overrides.
A phantom read occurs when the BeanOverrideBeanFactoryPostProcessor
retrieves a set of bean names by-type twice and a new bean definition
for a compatible type has been created in the BeanFactory by a
BeanOverrideHandler between the first and second retrieval.

Prior to this commit, the injection of test Bean Overrides (for
example, when using @MockitoBean) could fail in certain scenarios if
overrides were created for nonexistent beans "by type" without an
explicit name or qualifier. Specifically, if an override for a SubType
was created first, and subsequently an attempt was made to create an
override for a SuperType (where SubType extends SuperType), the
override for the SuperType would "override the override" for the
SubType, effectively removing the override for the SubType.
Consequently, injection of the override instance into the SubType field
would fail with an error message similar to the following.
BeanNotOfRequiredTypeException: Bean named 'Subtype#0' is expected to
be of type 'Subtype' but was actually of type 'Supertype$Mock$XHb7Aspo'
This commit addresses this issue by tracking all generated bean names
(in a generatedBeanNames set) and ensuring that a new bean override
instance is created for the current BeanOverrideHandler if a previous
BeanOverrideHandler already created a bean override instance that now
matches the type required by the current BeanOverrideHandler.
In other words, if the generatedBeanNames set already contains the
beanName that we just found by-type, we cannot "override the override",
because we would lose one of the overrides. Instead, we must create a
new override for the current handler. In the example given above, we
must end up with overrides for both SuperType and SubType.

This commit adapts AOT support in various modules after the RuntimeHints
and related deprecation changes.
`MemberCategory.INTROSPECT_*` hints are now removed and
`MemberCategory.*_FIELDS` are replaced with
`MemberCategory.INVOKE*_FIELDS` when invocation is needed.
Usage of `RuntimeHintsAgent` are also deprecated.
Closes gh-33847
As a follow up to commit 0088b9c7f8, this commit introduces an
integration test which verifies that a spy created via @MockitoSpyBean
using the MockReset.AFTER strategy is not reset between the refresh of
the ApplicationContext and the first use of the spy within a @Test
method.

Commit 6c2cba5d8a introduced a regression by inadvertently removing the
MockReset strategy comparison when resetting @MockitoBean and
@MockitoSpyBean mocks.
This commit reinstates the MockReset strategy check and introduces
tests for this feature.
Closes gh-33941
This commit upgrades our Mock Servlet classes for Servlet 6.1 support:
* the read/write `ByteBuffer` variants for `ServletInputStream` and
`ServletOutputStream` were not added as the default implementation
matches well the testing use case.
* Implement the session accessor with a simple lambda. Our mocks do not
simulate the scheduling of request/response processing on different
threads.
* Ensure that the response content length can only be written before the
response is committed. Calling those methods after commit is a no-op,
per specification.

This commit makes it clear that there are no visibility requirements
for @TestBean fields or factory methods as well as @MockitoBean or
@MockitoSpyBean fields.

This commit updates the Spring Framework baseline for the Servlet, JSP
and WebSocket APIs.
This also removes the previously deprecated APIs in JSP `PageContext`
and guards against the deprecation of the `PushBuilder` API.

This commit introduces a TestBeanReflectiveProcessor that registers
GraalVM native image reflection hints for a fully-qualified method name
configured via @TestBean.

Prior to this commit, the static factory methods in MockReset (such as
MockReset.before() and MockReset.after()) could only be applied to
beans within the ApplicationContext if the test class declared at least
one field annotated with either @MockitoBean or @MockitoSpyBean.
However, the Javadoc states that it should be possible to apply
MockReset directly to any mock in the ApplicationContext using the
static methods in MockReset.
To address that, this commit reworks the "enabled" logic in
MockitoResetTestExecutionListener as follows.
- We no longer check for the presence of annotations from the
org.springframework.test.context.bean.override.mockito package to
determine if MockReset is enabled.
- Instead, we now rely on a new isEnabled() method to determine if
MockReset is enabled.
The logic in the isEnabled() method still relies on the mockitoPresent
flag as an initial check; however, mockitoPresent only determines if
Mockito is present in the classpath. It does not determine if Mockito
can actually be used. For example, it does not detect if the necessary
reachability metadata has been registered to use Mockito within a
GraalVM native image.
To address that last point, the isEnabled() method performs an
additional check to determine if Mockito can be used in the current
environment. Specifically, it invokes Mockito.mockingDetails().isMock()
which in turn initializes core Mockito classes without actually
attempting to create a mock. If that fails, that means that Mockito
cannot actually be used in the current environment, which typically
indicates that GraalVM reachability metadata has not been registered
for the org.mockito.plugins.MockMaker in use (such as the
ProxyMockMaker).
In addition, isEnabled() lazily determines if Mockito can be
initialized, since attempting to detect that during static
initialization results in a GraalVM native image error stating that
Mockito internals were "unintentionally initialized at build time".
If Mockito cannot be initialized, MockitoResetTestExecutionListener
logs a DEBUG level message providing access to the corresponding stack
trace, and MockReset support is disabled.
Closes gh-33829
This commit verifies that MockReset.before() and MockReset.after() are
supported for beans within the ApplicationContext.
However, the test class must declare a field annotated with either
@MockitoBean or @MockitoSpyBean in order for the MockReset feature to
be triggered.

Spring Boot has honored @Primary for selecting which candidate bean
@MockBean and @SpyBean should mock or spy since Spring Boot 1.4.3;
however, the support for @Primary was not ported from Spring Boot to
Spring Framework's new Bean Overrides feature in the TestContext
framework.
To address that, this commit introduces support for @Primary for
selecting bean overrides -- for example, for annotations such as
@TestBean, @MockitoBean, and @MockitoSpyBean.
See https://github.com/spring-projects/spring-boot/issues/7621
Closes gh-33819
This commit introduces integration tests which verify that Bean
Overrides (for example, @MockitoBean and @MockitoSpyBean) can select
a single candidate bean to override when there are multiple candidates
that match the required type.
To "select" the desired bean, these tests rely on one of the following.
- explicit bean name in the bean override annotation
- explicit @Qualifier on the bean override field
- explicit @Primary on one of the candidate beans
However, the @Primary tests are currently @Disabled until @Primary
is honored in the Spring TestContext Framework.

Previously, we only looked at the OBJECT_TYPE_ATTRIBUTE on a
FactoryBean's bean definition; however this does not work for
situations where the information is provided by the definition's target
type rather than the attribute.
Rather than manually considering the target type in addition to the
existing consideration of the attribute, we now ask the BeanFactory for
the type that will be produced by the FactoryBean instead.

This commit introduces a test which verifies that @MockitoSpyBean on a
field with generics can be used to replace an existing bean with
matching generics that's produced by a FactoryBean that's
programmatically registered via an ImportBeanDefinitionRegistrar.
However, the test is currently @Disabled until the fix for
https://github.com/spring-projects/spring-boot/issues/40234 has been
ported to Spring Framework.

In gh-33602, we introduced strict singleton enforcement for bean
overrides -- for example, for @MockitoBean, @TestBean, etc. However,
the use of BeanFactory#isSingleton(beanName) can result in a
BeanCreationException for certain beans, such as a Spring Data JPA
FactoryBean for a JpaRepository.
In light of that, this commit relaxes the singleton enforcement in
BeanOverrideBeanFactoryPostProcessor by only checking the result of
BeanDefinition#isSingleton() for existing bean definitions.
This commit also updates the Javadoc and reference documentation to
reflect the status quo.
See gh-33602
Closes gh-33800
