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

Prior to this commit, we found in gh-35953 that using the `WebTestClient`
the following way leaks data buffers:
```
var body = client.get().uri("download")
.exchange()
.expectStatus().isOk()
.returnResult()
.getResponseBodyContent();
```
Here, the test performs expectations on the response status and headers,
but not on the response body. The WiretapConnector already supports this
case by subscribing to the Flux response body in those cases and
accumulating the entire content as a single byte[].
Here, the `DataBuffer` instances are not decoded by any `Decoder` and
are not released. This results in a memory leak.
This commit ensures that the automatic subscription in
`WiretapConnector` also releases the buffers automatically as the DSL
does not allow at that point to go back to performing body expectations.
Fixes gh-36050
Prior to this commit, if an enclosing test class (such as one annotated
with @SpringBootTest or simply @ExtendWith(SpringExtension.class))
was not annotated with @ContextConfiguration (or @Import with
@SpringBootTest), the ApplicationContext loaded for a @Nested test
class would not use any default context configuration for the enclosing
test class.
Effectively, a default XML configuration file or static nested
@Configuration class for the enclosing test class was not discovered
by the AbstractTestContextBootstrapper when attempting to build the
MergedContextConfiguration (application context cache key).
To address that, this commit introduces a new
resolveDefaultContextConfigurationAttributes() method in
ContextLoaderUtils which is responsible for creating instances of
ContextConfigurationAttributes for all superclasses and enclosing
classes. This effectively enables AbstractTestContextBootstrapper to
delegate to the resolved SmartContextLoader to properly detect a
default XML configuration file or static nested @Configuration class
even if such classes are not annotated with @ContextConfiguration.
Closes gh-31456
Prior to this commit, `RestTestClient` tests could only perform
expectations on the response without consuming the body. In this case,
the client could leak HTTP connections with the underlying HTTP library
because the response was not entirely read.
This commit ensures that the response is always fully drained before
performing expectations. The client is configured to buffer the response
content, so further body expectations are always possible.
Fixes gh-35784
If the RestClient was built with default message converters, then
in mutate, the saved builder also has 0 converters, and adding a
interferes with default registrations.
We need to check if there are no converters at all, and if so
use the default registrations.

Since getApplicationContext() was originally not intended to be part of
the public API, its Javadoc is intentionally sparse. However, since it
is actually a public API used by third parties, this commit improves the
documentation for getApplicationContext() by pointing out that invoking
the method actually results in the context being eagerly loaded, which
may not be desired.
This commit also updates the Javadoc for supportsParameter() along the
same lines.
Closes gh-35764
This commit picks up where commit a0baeae9cf left off.
Specifically, in order to align with the behavior of
AbstractMockHttpServletRequestBuilder, HtmlUnitRequestBuilder no longer
sets the local port in the MockHttpServletRequest.
See gh-35709
Prior to this commit, HtmlUnitRequestBuilder set the server port in the
MockHttpServletRequest to -1 if the URL did not contain an explicit
port. However, that can lead to errors in consumers of the request that
do not expect an invalid port number.
In addition, HtmlUnitRequestBuilder always set the remote port in the
MockHttpServletRequest to the value of the server port, which does not
make sense, since the remote port of the client has nothing to do with
the port on the server.
To address those issues, this commit revises HtmlUnitRequestBuilder so
that it:
- Does not set the server and local ports if the explicit or derived
default value is -1.
- Consistently sets the server and local ports to the same valid value.
- Does not set the remote port.
Closes gh-35709
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 adds AOT support for discovering @Nested test classes
within a @ClassTemplate test class, which includes
@ParameterizedClass test classes.

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).

Closes gh-35697
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.
