This commit reorganizes the asciidoctor attributes for the reference
documentation. Instead of being contributed partially by the build and
individual documents, attributes are now shared in common files that are
included in top sections.
This commit configures the documentation build to merge the entire
reference documentation into a single PDF file.
To achieve that, this commit also fixes duplicate anchors that were
introduced while factoring out common parts of the documentation for MVC
and WebFlux.
Closes gh-28451
This commit creates a new "framework-docs" module, which is dedicated to
documentation generation (reference and API docs).
This commit refactors the build configuration and moves the asciidoc
files to a separate location, but does not change the name nor the
nature of published artifacts.
Closes gh-29417
This commit improves the documentation for test execution events,
especially with regard to the fact that, by default, a
BeforeTestClassEvent is not published for the first test class using a
particular ApplicationContext.
This commit also introduces tests that verify the default behavior and
the ability to change the default behavior with a custom
TestExecutionListener that eagerly loads the context.
Closes gh-27757
This commit defines the doc-root and api-spring-framework attributes
once in docs.gradle instead of duplicating them in each *.adoc file.
This commit also introduces a new docs-spring-framework global
attribute.
This commit documents ApplicationContext initialization and shutdown
logging semantics for console output triggered in conjunction with the
Spring TestContext Framework.
Closes gh-25385
This commit introduces a new feature in the Spring TestContext
Framework (TCF) that provides support for recording application events
published in the ApplicationContext so that assertions can be performed
against those events within tests. All events published during the
execution of a single test are made available via the ApplicationEvents
API which allows one to process the events as a java.util.Stream.
The following example demonstrates usage of this new feature.
@SpringJUnitConfig(/* ... */)
@RecordApplicationEvents
class OrderServiceTests {
@Autowired
OrderService orderService;
@Autowired
ApplicationEvents events;
@Test
void submitOrder() {
// Invoke method in OrderService that publishes an event
orderService.submitOrder(new Order(/* ... */));
// Verify that an OrderSubmitted event was published
int numEvents = events.stream(OrderSubmitted.class).count();
assertThat(numEvents).isEqualTo(1);
}
}
To enable the feature, a test class must be annotated or meta-annotated
with @RecordApplicationEvents. Behind the scenes, a new
ApplicationEventsTestExecutionListener manages the registration of
ApplicationEvents for the current thread at various points within the
test execution lifecycle and makes the current instance of
ApplicationEvents available to tests via an @Autowired field in the
test class. The latter is made possible by a custom ObjectFactory that
is registered as a "resolvable dependency". Thanks to the magic of
ObjectFactoryDelegatingInvocationHandler in the spring-beans module,
the ApplicationEvents instance injected into test classes is
effectively a scoped-proxy that always accesses the ApplicationEvents
managed for the current test.
The current ApplicationEvents instance is stored in a ThreadLocal
variable which is made available in the ApplicationEventsHolder.
Although this class is public, it is only intended for use within the
TCF or in the implementation of third-party extensions.
ApplicationEventsApplicationListener is responsible for listening to
all application events and recording them in the current
ApplicationEvents instance. A single
ApplicationEventsApplicationListener is registered with the test's
ApplicationContext by the ApplicationEventsTestExecutionListener.
The SpringExtension has also been updated to support parameters of type
ApplicationEvents via the JUnit Jupiter ParameterResolver extension
API. This allows JUnit Jupiter based tests to receive access to the
current ApplicationEvents via test and lifecycle method parameters as
an alternative to @Autowired fields in the test class.

gh-19930 introduced support for finding class-level test configuration
annotations on enclosing classes when using JUnit Jupiter @Nested test
classes, but support for @DynamicPropertySource methods got overlooked
since they are method-level annotations.
This commit addresses this shortcoming by introducing full support for
@NestedTestConfiguration semantics for @DynamicPropertySource methods
on enclosing classes.
Closes gh-26091
This commit introduces support for discovering @Sql, @SqlGroup,
@SqlConfig, and @SqlMergeMode on enclosing classes for @Nested test
classes in JUnit Jupiter.
Closes gh-25913
