In the original implementation of
MicrometerObservationRegistryTestExecutionListener I accidentally
imported JUnit 5's org.junit.platform.launcher.TestExecutionListener
instead Spring's
org.springframework.test.context.TestExecutionListener. The code
therefore attempts to use the ClassLoader for the JUnit Platform's
TestExecutionListener which may fail to see the required types. In
addition, if the JUnit Platform's TestExecutionListener is not on the
classpath, the attempt to access its ClassLoader will fail.
This commit addresses this by properly using the ClassLoader for
Spring's TestExecutionListener to detect dependencies of the
MicrometerObservationRegistryTestExecutionListener.
Closes gh-30726
This commit overhauls the TestExecutionListener for Micrometer's
ObservationRegistry that was introduced in the previous commit.
Specifically, this commit:
- Renames the listener to MicrometerObservationRegistryTestExecutionListener
since the use of a ThreadLocal is an implementation detail that may
change over time.
- Makes the listener package-private instead of public in order to
allow the team greater flexibility in evolving this feature.
- Eagerly loads the ObservationThreadLocalAccessor class and verifies
that it has a getObservationRegistry() method to ensure that the
listener is properly skipped when SpringFactoriesLoader attempts to
load it, if Micrometer 1.10.8+ is not on the classpath.
- Switches the listener's automatic registration order to 2500 in order
to register it after the DependencyInjectionTestExecutionListener.
- Only tracks the previous ObservationRegistry in beforeTestMethod() if
the test's ApplicationContext contains an ObservationRegistry bean.
- Properly removes the TestContext attribute for the previous
ObservationRegistry in afterTestMethod().
- Introduces DEBUG logging for diagnostics.
- Adds an entry in the Javadoc for TestExecutionListener as well as in
the Testing chapter in the reference manual.
Closes gh-30658
Prior to this commit, there was no way to specify the
ObservationRegistry that is registered in the given test's
ApplicationContext as the one that should be used by Micrometer's
ObservationThreadLocalAccessor for context propagation.
This commit introduces a TestExecutionListener for Micrometer's
ObservationRegistry in the Spring TestContext Framework. Specifically,
this listener obtains the ObservationRegistry registered in the test's
ApplicationContext, stores it in ObservationThreadLocalAccessor for the
duration of each test method execution, and restores the original
ObservationRegistry in ObservationThreadLocalAccessor after each test.

In the previous commit which introduced the new context failure threshold
support in the TestContext framework, the context failure tracking was
tied to an instance of DefaultCacheAwareContextLoaderDelegate.
Consequently, the feature was only supported within a given test class.
This commit therefore moves context failure tracking to the ContextCache
SPI (and DefaultContextCache) so that the feature applies to all test
classes within the current test suite (i.e., JVM).
This commit also includes the total failure count in the statistics
logged by the DefaultContextCache.
See gh-14182
This commit makes the failure threshold value configurable via a JVM
system property or Spring property named
"spring.test.context.failure.threshold".
See gh-14182
This commit introduces initial support for a new "context failure
threshold" feature in the Spring TestContext Framework (TCF).
Specifically, DefaultCacheAwareContextLoaderDelegate now tracks how
many times a failure occurs when attempting to load an
ApplicationContext and preemptively throws an IllegalStateException for
subsequent attempts to load the same context if the configured failure
threshold has been exceeded.

This commit refines how GraalVM tracing agent detection works
for both test and application executions.
It rolls back the introduction of TestAotDetector done in 111309605c
and instead updates AotDetector.useGeneratedArtifacts()
to only detect "buildtime" and "runtime" imagecode system
property values by leveraging a new method
NativeDetector.inNativeImage(NativeDetector.Context...).
This commit also adds a workaround for
https://github.com/oracle/graal/issues/6691.
Closes gh-30511
This commit improves how the build deals with javadoc invalid references
in two ways.
Link/see references that are temporarily invalid during javadoc
generation of individual modules are better masked by using the option
`Xdoclint:syntax` instead of `Xdoclint:none` (warnings were still
visible in some cases, e.g. when individually building the javadoc for
a specific module).
Global javadoc-building task `api` now combines `syntax` and `reference`
`Xdoclint` groups, allowing to raise truly invalid references even when
all the modules have been aggregated.
This commit also fixes the 20+ errors which appeared following the later
change in doclet configuration.
Closes gh-30428
Prior to this commit, the SpringExtension looked up the
TestInstance.Lifecycle and ExecutionMode using
TestContextAnnotationUtils; however, using TestContextAnnotationUtils is
problematic since the TestInstance.Lifecycle and ExecutionMode can be
configured globally via configuration parameters instead of locally via
the @TestInstance and @Execution annotations.
This commit addresses these issues by looking up the
TestInstance.Lifecycle and ExecutionMode via JUnit Jupiter's
ExtensionContext which takes into account both global and local
configuration.
See gh-30020
Prior to this commit, test AOT processing failed when using the GraalVM
tracing agent and GraalVM Native Build Tools (NBT) plugins for Maven
and Gradle.
The reason is that the AOT support in the TestContext framework (TCF)
relied on AotDetector.useGeneratedArtifacts() which delegates
internally to NativeDetector.inNativeImage() which does not
differentiate between values stored in the
"org.graalvm.nativeimage.imagecode" JVM system property.
This commit addresses this issue by introducing a TestAotDetector
utility that is specific to the TCF. This detector considers the
current runtime to be in "AOT runtime mode" if the "spring.aot.enabled"
Spring property is set to "true" or the GraalVM
"org.graalvm.nativeimage.imagecode" JVM system property is set to any
non-empty value other than "agent".
Closes gh-30281
This commit modifies the way the `@RecordApplicationEvents` annotation
works in tests, allowing for capture of events from threads other than
the main test thread (async events) and for the assertion of captured
event from a separate thread (e.g. when using `Awaitility`).
This is done by switching the `ApplicationEventsHolder` to use an
`InheritedThreadLocal`.
There is a mutual exclusion between support of asynchronous events vs
support of JUnit5 parallel tests with the `@TestInstance(PER_CLASS)`
mode. As a result, we favor the former and now `SpringExtension` will
invalidate a test class that is annotated (or meta-annotated, or
enclosed-annotated) with `@RecordApplicationEvents` AND
`@TestInstance(PER_CLASS)` AND `@Execution(CONCURRENT)`.

This commit adds assertions to MockMvc's CookieresultMatchers:
- `attribute` for arbitrary attributes
- `sameSite` for the SameSite well-known attribute
Note that the `sameSite` methods delegate to their `attribute`
counterparts. Note also that Jakarta's `Cookie#getAttribute` method is
case-insensitive, which is reflected in the documentation of the
`attribute` assertion method and the tests.

This commit refactors some AssertJ assertions into more idiomatic and
readable ones. Using the dedicated assertion instead of a generic one
will produce more meaningful error messages.
For instance, consider collection size:
```
// expected: 5 but was: 2
assertThat(collection.size()).equals(5);
// Expected size: 5 but was: 2 in: [1, 2]
assertThat(collection).hasSize(5);
```
Closes gh-30104
This commit changes the name of two recently introduced methods in the
`MockRestRequestMatchers` class for header and queryParam. These have
been found to cause false negatives in user tests, due to the new
overload taking precedence in some cases.
Namely, using a `Matcher` factory method which can apply to both `List`
and `String` will cause the compiler to select the newest list overload,
by instantiating a `Matcher<Object>`.
This can cause false negatives in user tests, failing tests that used
to pass because the Matcher previously applied to the first String in
the header or queryParam value list. For instance, `equalsTo("a")`.
The new overloads are recent enough and this has enough potential to
cause an arbitrary number of user tests to fail that we break the API
to eliminate the ambiguity, by renaming the methods with a `*List`
suffix.

This commit picks up where the two previous commits left off.
Specifically, this commit:
- Removes the "severity=warning" configuration to ensure that violations
actually fail the build.
- Fixes regular expressions for suppressions by matching forward
slashes using `[\\/]` instead of `\/`.
- Moves the configuration for newly introduced checks to locations in
checkstyle.xml that align with the existing organization of that file.
- Renames the IDs for RegexpSinglelineJava checks from
javaDocPackageNonNullApiAnnotation/javaDocPackageNonNullFieldsAnnotation
to packageLevelNonNullApiAnnotation/packageLevelNonNullFieldsAnnotation,
respectively, since these checks are not related to Javadoc.
- Simplifies the null-safety annotation checks to match against
imported annotation types, which enforces consistency across
package-info.java files for the annotation declarations.
- Simplifies the RegEx for JavadocPackage suppressions to only exclude
packages not under src/main/java (vs src/main) and those in the
framework-docs module.
- Consistently suppresses all checks for the `asm`, `cglib`, `objenesis`,
and `javapoet` packages in spring-core.
- Adds explicit suppressions for null-safety annotations for the `lang`
package in spring-core.
- Adds explicit suppressions for null-safety annotations for the
`org.aopalliance` package in spring-aop.
- Revises the RegEx for null-safety annotation suppressions to only
exclude package-info.java files not under src/main/java and
additionally to exclude package-info.java files in the framework-docs
module as well as those in the spring-context-indexer,
spring-instrument, and spring-jcl modules.
- Adds all missing package-info.java files.
- Adds null-safety annotations to package-info.java files where
appropriate.

This commit adds a `header` variant and a `queryParam` variant to the
`MockRestRequestMatchers` API which take a single `Matcher` over the
list of values.
Contrary to the vararg variants, the whole list is evaluated and the
caller can choose the desired semantics using readily-available iterable
matchers like `everyItem`, `hasItems`, `hasSize`, `contains` or
`containsInAnyOrder`...
The fact that the previous variants don't strictly check the size of the
actual list == the number of provided matchers or expected values is
now documented in their respective javadocs.

Prior to this commit, a recent change applied in gh-29125 changed the
behavior of `MockHttpServletRequest` instances. In case of an empty
request body, the returned `InputStream` would be static and could not

This commit takes rfc8297 into account and introduces a newer code 103
HttpStatus value which uses `Early Hints` as the more correct reason
phrase, deprecating the outdated `CHECKPOINT` enum value for 103.
Additionally:
- `HttpStatus.valueOf(103)` will return the new enum value
- `HttpStatusCode#isSameCodeAs(HttpStatusCode)` is introduced to ease
comparison of deprecated enums vs their newer counterparts (or any
instance of a more generic `HttpStatusCode`) by comparing the integer
`value()`
- `HttpStatusTests` covers the new deprecation as well as the three
previously deprecated codes, including a check with the above new
method to ensure they have comparable integer values

As the DSL internally calls `ResultActions.andExpect`, this is done with
a trick where a synthetic `ResultActions` is provided at top level which
stores each `ResultMatcher` in a mutable list.
Once the DSL usage is done, the top level DSL `andExpectAll` turns that
list into a `vararg` passed down to the actual `actions.andExpectAll`.

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.
See gh-29132
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.

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.

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 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.

- 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

Prior to this commit, the AOT runtime support in the Spring TestContext
Framework (TCF) relied on the MergedContextConfiguration for a given
test class being the same as during the AOT processing phase. However,
this is not always the case. For example, Spring Boot "disables"
selected `ContextCustomizer` implementations during AOT runtime
execution.
See 0f325f98b5
To address that, this commit ensures that context caching works
properly during AOT runtime execution even if the
MergedContextConfiguration differs from what was produced during the
AOT processing phase. Specifically, this commit introduces
AotMergedContextConfiguration which is a MergedContextConfiguration
implementation based on an AOT-generated ApplicationContextInitializer.
AotMergedContextConfiguration wraps the MergedContextConfiguration
built during AOT runtime execution.
Interactions with the ContextCache are performed using the
AotMergedContextConfiguration; whereas, the ApplicationContext is
loaded using the original MergedContextConfiguration.
This commit also introduces a ContextCustomizerFactory that emulates
the ImportsContextCustomizerFactory in Spring Boot's testing support.
BasicSpringJupiterImportedConfigTests uses @Import to verify that the
context customizer works, and AotIntegrationTests has been updated to
execute BasicSpringJupiterImportedConfigTests after test classes whose
MergedContextConfiguration is identical during AOT runtime execution.
Without the fix in this commit, BasicSpringJupiterImportedConfigTests
would fail in AOT runtime mode since its ApplicationContext would be
pulled from the cache using an inappropriate cache key.
Closes gh-29289
Prior to this commit, the abstract base test classes for JUnit 4 and
TestNG registered explicit sets of TestExecutionListeners. This
configuration was useful in the early years of the Spring TestContext
Framework. However, since the introduction of support for automatic
registration of "default" listeners in Spring Framework 4.1, these
predefined sets of TestExecutionListeners have become a hindrance to
using Spring's testing support with default listeners from Spring
portfolio projects (such as Spring Boot and Spring Security) as well as
third-party or project-specific default listeners.
To address this issue, the four abstract base test classes for JUnit 4
and TestNG no longer declare listeners via @TestExecutionListeners and
instead now rely on registration of default listeners.

Prior to this commit, ExchangeResult.assertWithDiagnostics() threw an
IllegalArgumentException for a custom HTTP status code since toString()

format the HttpStatus and falling back to formatting the raw integer
status code.

TestClassScanner was made public with the assumption that Spring Boot's
AOT testing support might need to work directly with that class; however,
it turns out that Spring Boot does not currently have such a need.
In light of that, this commit restores TestClassScanner's visibility to
package private.
Prior to this commit, the TestRuntimeHintsRegistrar API combined
processing of MergedContextConfiguration and test classes. However, it
appears that only spring-test internals have a need for registering
hints based on the MergedContextConfiguration. For example, Spring
Boot's AOT testing support has not had such a need, and it is assumed
that third parties likely will not have such a need.
In light of that, this commit simplifies the TestRuntimeHintsRegistrar
API so that it focuses on processing of a single test class.
In addition, this commit moves the hint registration code specific to
MergedContextConfiguration to an internal mechanism.
