This commit raises the minimum Coroutines version supported
to 1.4.0-M1 and above, and changes usages of awaitFirst() or
awaitFirstOrNull() to awaitSingle() or awaitSingleOrNull()
to fix gh-25007.
Closes gh-25914
Closes gh-25007
Prior to this commit, the EnclosingConfiguration mode used in
conjunction with @NestedTestConfiguration defaulted to INHERIT.
In other to allow development teams to change the default to OVERRIDE
(e.g., for compatibility with Spring Framework 5.0 through 5.2), this
commit introduces support for changing the default EnclosingConfiguration
mode globally via a JVM system property or via the SpringProperties
mechanism.
For example, the default may be changed to
EnclosingConfiguration.OVERRIDE by supplying the following JVM system
property via the command line.
-Dspring.test.enclosing.configuration=override

Prior to this commit (and since Spring Framework 5.0), Spring's
integration with JUnit Jupiter supported detection of test
configuration (e.g., @ContextConfiguration, etc.) on @Nested classes.
However, if a @Nested class did not declare its own test configuration,
Spring would not find the configuration from the enclosing class. This
is in contrast to Spring's support for automatic inheritance of test
configuration from superclasses. The only workaround was to
copy-n-paste the entire annotation configuration from enclosing classes
to nested tests classes, which is cumbersome and error prone.
This commit introduces a new @NestedTestConfiguration annotation that
allows one to choose the EnclosingConfiguration mode that Spring should
use when searching for test configuration on a @Nested test class.
Currently, the options are INHERIT or OVERRIDE, where the current
default is OVERRIDE. Note, however, that the default mode will be
changed to INHERIT in a subsequent commit. In addition, support will be
added to configure the global default mode via the SpringProperties
mechanism in order to allow development teams to revert to the behavior
prior to Spring Framework 5.3.
As of this commit, inheritance of the following annotations is honored
when the EnclosingConfiguration mode is INHERIT.
- @ContextConfiguration / @ContextHierarchy
- @ActiveProfiles
- @TestPropertySource / @TestPropertySources
- @WebAppConfiguration
- @TestConstructor
- @BootstrapWith
- @TestExecutionListeners
- @DirtiesContext
- @Transactional
- @Rollback / @Commit
This commit does NOT include support for inheriting the following
annotations on enclosing classes.
- @Sql / @SqlConfig / @SqlGroup
In order to implement this feature, the search algorithms in
MetaAnnotationUtils (and various other spring-test internals) have been
enhanced to detect when annotations should be looked up on enclosing
classes. Other parts of the ecosystem may find the new
searchEnclosingClass() method in MetaAnnotationUtils useful to provide
similar support.
As a side effect of the changes in this commit, validation of user
configuration in repeated @TestPropertySource declarations has been
removed, but this may be reintroduced at a later date.
Closes gh-19930
This commit adds support for Kotlin Coroutines suspending functions to
Spring MVC, by converting those to a Mono that can then be handled by
the asynchronous request processing feature.
It also optimizes Coroutines detection with the introduction of an
optimized KotlinDetector.isSuspendingFunction() method that does not
require kotlin-reflect.
Closes gh-23611
