To slightly improve performance, this commit switches to
StringBuilder.append(char) instead of StringBuilder.append(String)
whenever we append a single character to a StringBuilder.

This commit revises the fix submitted in 959e6d1745 by ensuring that
empty file input is converted to a MockPart with the supplied name, an
empty filename, "application/octet-stream" as the content type, and
empty content.
This aligns with the behavior of Servlet containers, as tested with the
interaction between Firefox and a standard Servlet running in a Jetty
Servlet container.
Closes gh-26799
Prior to this commit, when using HtmlUnit with empty file input,
MockMvc's HtmlUnitRequestBuilder would throw a NullPointerException
when attempting to create a MockPart based on the null File.
This commit ensures that empty file input is converted to a MockPart
with a valid name but with a null filename, a null content type, and
empty content.

Prior to this commit, if a test class annotated with @DirtiesContext
and @EnabledIf/@DisabledIf with `loadContext = true` was disabled due
to the evaluated SpEL expression, the ApplicationContext would not be
marked as dirty and closed.
The reason is that @EnabledIf/@DisabledIf are implemented via JUnit
Jupiter's ExecutionCondition extension API which results in the entire
test class (as well as any associated extension callbacks) being
skipped if the condition evaluates to `disabled`. This effectively
prevents any of Spring's TestExecutionListener APIs from being invoked.
Consequently, the DirtiesContextTestExecutionListener does not get a
chance to honor the class-level @DirtiesContext declaration.
This commit fixes this by implementing part of the logic of
DirtiesContextTestExecutionListener in
AbstractExpressionEvaluatingCondition (i.e., the base class for
@EnabledIf/@DisabledIf support). Specifically, if the test class for an
eagerly loaded ApplicationContext is disabled,
AbstractExpressionEvaluatingCondition will now mark the test
ApplicationContext as dirty if the test class is annotated with
@DirtiesContext.

Prior to this commit, MockHttpServletResponse only included the Expires
attribute in the generated Cookie header if the Max-Age attribute had
also been set.
This commit supports including the Expires attribute in the generated
Cookie Header even when the Max-Age attribute has not been set.
Closes gh-26558
This commit changes the condition in the if-block to check the number of
available processors instead of currently active threads with the hope
that doing so will prove more reliable on the CI server.
Previously this method returned headers only when a Content-Type part header
was present. Now it is guaranteed to return headers (possibly empty) as long
as there is a MultipartFile or Part with the given name.
Closes gh-26501
Prior to this commit, calls to setLocale() MockHttpServletResponse
would result in a NullPointerException if the supplied Locale was null.
Although the Javadoc for setLocale(Locale) and addHeader(String, String)
in javax.servlet.ServletResponse does not specify how a null
Locale should be handled, both Tomcat and Jetty simply ignore a null
value.
This commit therefore updates MockHttpServletResponse to silently
ignore a null Locale passed to setLocale().
Closes gh-26493
Prior to this commit, calls to setHeader() and addHeader() in
MockHttpServletResponse would result in an IllegalArgumentException or
NullPointerException if the supplied header value was null.
Although the Javadoc for setHeader(String, String) and
addHeader(String, String) in javax.servlet.http.HttpServletResponse
does not specify how a null header value should be handled, both Tomcat
and Jetty simply ignore a null value. Furthermore,
org.springframework.http.HttpHeaders.add(String, String) declares the
headerValue parameter as @Nullable.
This commit therefore updates MockHttpServletResponse to silently
ignore null header values passed to setHeader() and addHeader().
Closes gh-26488
Prior to this commit, if the DataSource in the
DataSourceFromTransactionManager was wrapped in a proxy implementing
InfrastructureProxy, SqlScriptsTestExecutionListener would throw an
exception stating that the DataSource in the ApplicationContext and the
DataSource in the DataSourceFromTransactionManager were not the same.
This commit unwraps both data sources and compares the underlying
target instances to check for equality.
In addition, this commit makes the unwrapResourceIfNecessary() method in
TransactionSynchronizationUtils public.

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.

This commit introduces computeAttribute() as an interface default method
in the AttributeAccessor API. This serves as a convenience analogous to
the computeIfAbsent() method in java.util.Map.
