Prior to this commit, if AOT processing of a test's ApplicationContext
failed, the TestContext Framework (TCF) still attempted to load the
context via standard (JVM) mechanisms when running in AOT mode.
For example, if a test class uses Spring Boot's @MockBean, AOT
processing of that test's context will fail with a WARN log message,
and there will no mapping from that test class to an AOT-generated
ApplicationContextInitializer (ACI). Consequently, when the test suite
is run in AOT mode that particular test class will currently fail with
a confusing stack trace due to the fact that Spring Boot's
SpringApplication attempts to locate a "main" ACI instead of the
missing "test" ACI (missing because it was not generated during AOT
processing).
In general, the TCF should not attempt to load an ApplicationContext in
"JVM mode" while running in "AOT mode".
This commit therefore reworks the logic in
DefaultCacheAwareContextLoaderDelegate to fail fast (with a meaningful
error message) if an AOT-generated ACI cannot be found while running in
AOT mode. This avoids the aforementioned confusion when @MockBean tests
fail in AOT mode (on the JVM or within a native image), and it also
helps to diagnose build problems if AOT processing has not yet been
performed for the project's test suite.

SocketUtils was officially deprecated in 5.3.16 (gh-28052) and removed
in 6.0 M3 (gh-28054); however, there is still need for a subset of this
functionality in integration tests for testing scenarios in which it is
not possible for the system under test to select its own random port
(or rely on the operating system to provide an ephemeral port).
This commit therefore introduces a scaled down version in the
spring-test module called TestSocketUtils which supports retrieval of a
single TCP port.

Prior to this commit, it was possible to register hints for individual
test classes programmatically via the
org.springframework.test.context.aot.TestRuntimeHintsRegistrar SPI;
however, that requires that a custom TestRuntimeHintsRegistrar be
registered via "META-INF/spring/aot.factories". In addition,
implementing a TestRuntimeHintsRegistrar is more cumbersome than using
the core mechanisms such as @Reflective, @ImportRuntimeHints, and
@RegisterReflectionForBinding.
This commit address this by introducing support for @Reflective and
@ImportRuntimeHints on test classes. @RegisterReflectionForBinding
support is available automatically since it is an extension of the
@Reflective mechanism.

This commit reverts changes to AbstractCacheManager since iterating
over the caches in a for-loop and a stream is duplicated effort.
This commit reverts changes to DefaultRenderingResponseBuilder,
RouterFunctions, and OriginHandshakeInterceptor since order matters for
those use cases: they were originally based on the semantics of
LinkedHashSet or LinkedHashMap; whereas, Set.copyOf() and Map.copyOf()
do not provide any guarantees regarding ordering.
This commit also applies analogous changes to "sibling" implementations
across Servlet mocks as well as Web MVC and WebFlux.

At the request of the Spring Boot team, ApplicationContextFailureProcessor
implementations are now loaded via the spring.factories mechanism
instead of supporting a single processor registered via subclasses of
AbstractTestContextBootstrapper.
This makes the retrieval and handling of processors internal to
DefaultCacheAwareContextLoaderDelegate, while simultaneously supporting
multiple processors that can be registered by anyone (i.e., not
limited to projects that implement custom TestContextBootstrappers).

For a Spring Boot test, Logback logs at DEBUG level by default until
Spring Boot's logging infrastructure has a chance to take control, and
this can result in a considerable amount of INFO and DEBUG output.
It's not the number of lines that causes an issue. Rather, it's the
amount of information in each line that can become overwhelming,
especially when the MergedContextConfiguration is complex.
The main reason for lengthy DEBUG logging in a Spring Boot test is that
Spring Boot's ImportsContextCustomizer implements toString() which
results in logging of the fully qualified class names of all imported
configuration classes. In an example using @WebMvcTest, this resulted
in logging of 27 imported classes twice. However, the lists of
registered TestExecutionListener, ContextCustomizerFactory, and
ContextCustomizer implementations are also logged separately, and that
adds quite a bit of noise at DEBUG level.
This commit addresses these issues and simultaneously completely
revises logging within the Spring TestContext Framework (TCF).
- Numerous log statements are now logged at TRACE level instead of
DEBUG.
- Numerous log statements now have two modes. When logging at TRACE
level, fully qualified class names (or the results of invoking
toString() on related components) are included. When logging at DEBUG
level, simple names of classes are logged and the results of invoking
toString() on related components are omitted.
- toString() implementations in TCF components are now based on the
newly introduced SimpleValueStyler for ToStringCreator.
The combination of the above changes greatly reduces the amount of
DEBUG logging output in the TCF, but users can still access complete
details by switching to TRACE level logging.

This commit exposes a "spring.aot.processing" system property when the
AOT engine is running. This can be used by code that need to react
differently when the application is being refreshed for AOT processing.
Closes gh-29340
This commit introduces an ApplicationContextFailureProcessor SPI in the
Spring TestContext Framework that allows third parties to process
failures that occur while a SmartContextLoader attempts to load an
ApplicationContext.
SmartContextLoader implementations must introduce a try-catch block
around the loading code and throw a ContextLoadException that wraps
the failed ApplicationContext and the cause of the failure.
Extensions of AbstractTestContextBootstrapper can configure an
ApplicationContextFailureProcessor by overriding the new protected
getApplicationContextFailureProcessor() method.
DefaultCacheAwareContextLoaderDelegate unwraps any ContextLoadException
and delegates to the configured ApplicationContextFailureProcessor for
processing.
Closes gh-28826
There's currently a considerable amount of overlap between the
implementations of AotProcessor and TestAotProcessor. In addition
AotProcessor is abstract and does not include a main() method; whereas,
TestAotProcessor is concrete and does include a main() method.
To address these issues, this commit:
- Introduces an AbstractAotProcessor base class that AotProcessor and
TestAotProcessor now both extend
- Moves common properties/functionality to AbstractAotProcessor
- Renames AotProcessor to ContextAotProcessor
- Makes TestAotProcessor abstract like ContextAotProcessor
- Removes the main() method from TestAotProcessor
Closes gh-29266
