This commit reorders and clarifies the usage instructions for
ApplicationEvents to:
1. Recommend method parameter injection as the primary approach, since
ApplicationEvents has a per-method lifecycle
2. Clarify that ApplicationEvents is not a general Spring bean and
cannot be constructor-injected
3. Explicitly state that field injection is an alternative approach
This addresses confusion where developers expect ApplicationEvents to
behave like a regular Spring bean eligible for constructor injection.

The setProperty() and withProperty() methods in MockEnvironment were
originally introduced with (String, String) signatures; however, they
should have always had (String, Object) signatures in order to comply
with the MockPropertySource and PropertySource APIs.
To address that, this commit introduces variants of these methods that
accept Object values for properties.
Closes gh-34947
Prior to this commit, bean overrides (such as @MockitoBean, etc.) were
discovered multiple times if they were declared:
- at the type-level on an interface that is implemented at more than
one level in the type hierarchy, the enclosing class hierarchy, or a
combination of the type and enclosing class hierarchies.
or
- on a field declared in a class which can be reached multiple times
while traversing the type and enclosing class hierarchies in
scenarios such as the following: the class (X) in which the field is
declared is a supertype of an enclosing type of the test class, and X
is also an enclosing type of a supertype of the test class.
Such scenarios resulted in an IllegalStateException stating that a
duplicate BeanOverrideHandler was discovered.
To address that, this commit revises the search algorithm in
BeanOverrideHandler so that all types (superclasses, enclosing classes,
and implemented interfaces) are only visited once while traversing the
type and enclosing class hierarchies in search of bean override
handlers.

This commit provides first-class support for Bean Overrides
(@MockitoBean, @MockitoSpyBean, @TestBean, etc.) with
@ContextHierarchy.
Specifically, bean overrides can now specify which ApplicationContext
they target within the context hierarchy by configuring the
`contextName` attribute in the annotation. The `contextName` must match
a corresponding `name` configured via @ContextConfiguration.
For example, the following test class configures the name of the second
hierarchy level to be "child" and simultaneously specifies that the
ExampleService should be wrapped in a Mockito spy in the context named
"child". Consequently, Spring will only attempt to create the spy in
the "child" context and will not attempt to create the spy in the
parent context.
@ExtendWith(SpringExtension.class)
@ContextHierarchy({
@ContextConfiguration(classes = Config1.class),
@ContextConfiguration(classes = Config2.class, name = "child")
})
class MockitoSpyBeanContextHierarchyTests {
@MockitoSpyBean(contextName = "child")
ExampleService service;
// ...
}

For bean override support (@MockitoBean, @TestBean, etc.), the logic
for field injection previously resided in the BeanOverrideRegistry
which resulted in a strange mixture of concerns.
To address that, this commit moves the field injection logic to the
BeanOverrideTestExecutionListener, and the BeanOverrideRegistry now
serves a single role, namely the role of a registry.
Closes gh-34726
Prior to this commit, the Test Bean Override feature provided support
for overriding beans based on qualifier annotations in several
scenarios; however, qualifier annotations got lost if they were
declared on the return type of the @Bean method for the bean being
overridden and the @BeanOverride (such as @MockitoBean) was based on
a supertype of that return type.
To address that, this commit sets the @BeanOverride field as the
"qualified element" in the RootBeanDefinition to ensure that qualifier
annotations are available for subsequent autowiring candidate
resolution.
Closes gh-34646
Prior to this commit, MockCookie.parse() failed with an
IllegalArgumentException when attempting to parse a custom attribute
with a value, such as "Version=1". This is a regression that was
inadvertently introduced in 7fc4937199
when adding support for the "Partitioned" attribute which does not
support a value.
This commit addresses this regression by parsing both the name and the
value from an optional, custom attribute.

This commit introduces a new loadContextForAotProcessing(...) variant
in AotContextLoader which accepts a RuntimeHints argument. This new
method is an interface default method which delegates to the existing
loadContextForAotProcessing(MergedContextConfiguration) variant for
backward compatibility.
In addition, the original loadContextForAotProcessing(...) variant is
now deprecated and has been converted to an interface default method
which throws an UnsupportedOperationException.
Note, however, that the framework now only invokes the new
loadContextForAotProcessing(...) variant within TestContextAotGenerator.
Closes gh-34513
Prior to this commit, `MockHttpServletResponse` would only support
adding a `Content-Language` once. Adding multiple header values would
always replace the content-language property in the response and the
entire header value.
This commit ensures that this behavior is supported.
Fixes gh-34488
Prior to this commit, `MockHttpServletResponse#setHeader` would not
remove the header entry when given a `null` value, as documented in the
Servlet API.
This commit ensures that this behavior is enforced.
Fixes gh-34464
Prior to this commit, @MockitoSpyBean could only be declared on fields
within test classes, which prevented developers from being able to
easily reuse spy configuration across a test suite.
With this commit, @MockitoSpyBean is now supported at the type level
on test classes, their superclasses, and interfaces implemented by
those classes. @MockitoSpyBean is also supported on enclosing classes
for @Nested test classes, their superclasses, and interfaces
implemented by those classes, while honoring @NestedTestConfiguration
semantics.
In addition, @MockitoSpyBean:
- has a new `types` attribute that can be used to declare the type or
types to spy when @MockitoSpyBean is declared at the type level
- can be declared as a repeatable annotation at the type level
- can be declared as a meta-annotation on a custom composed annotation
which can be reused across a test suite (see the @SharedSpies
example in the reference manual)
To support these new features, this commit also includes the following
changes.
- MockitoSpyBeanOverrideProcessor has been revised to support
@MockitoSpyBean at the type level.
- The "Bean Overriding in Tests" and "@MockitoBean and
@MockitoSpyBean" sections of the reference manual have been fully
revised.

Prior to this commit, the order values of TestExecutionListener
implementations were hard-coded in their getOrder() methods.
To benefit users and integrators, this commit exposes those order values
as an ORDER constant in each TestExecutionListener.

Closes gh-34404
Changes made to the Bean Override search algorithms in commit
9181cce65f resulted in a regression that caused tests to start failing
due to duplicate BeanOverrideHandlers under the following circumstances.
- An enclosing class (typically a top-level test class) declares a
@BeanOverride such as @MockitoBean.
- An inner class is declared in that enclosing class.
- A @Nested test class which extends that inner class is declared in
the same enclosing class.
The reason for the duplicate detection is that the current search
algorithm visits the common enclosing class twice.
To address that, this commit revises the search algorithm in
BeanOverrideHandler so that enclosing classes are only visited once.
See gh-33925
Closes gh-34324
Prior to this commit, test bean overrides (for example, @MockitoBean,
@TestBean, etc.) eagerly honored the name of the annotated field as a
fallback qualifier, effectively ignoring @Primary and @Fallback
semantics for certain use cases.
This led to situations where a bean override for a test would select a
different bean than the core container would for the same autowiring
metadata.
To address that, this commit revises the implementation of
BeanOverrideBeanFactoryPostProcessor so that @Primary and @Fallback
semantics are consistently honored before attempting to use the
annotated field's name as a fallback qualifier.
Closes gh-34374
Prior to this commit, @MockitoBean could only be declared on fields
within test classes, which prevented developers from being able to
easily reuse mock configuration across a test suite.
With this commit, @MockitoBean is now supported at the type level on
test classes, their superclasses, and interfaces implemented by those
classes. @MockitoBean is also supported on enclosing classes for
@Nested test classes, their superclasses, and interfaces implemented
by those classes, while honoring @NestedTestConfiguration semantics.
In addition, @MockitoBean:
- has a new `types` attribute that can be used to declare the type or
types to mock when @MockitoBean is declared at the type level
- can be declared as a repeatable annotation at the type level
- can be declared as a meta-annotation on a custom composed annotation
which can be reused across a test suite (see the @SharedMocks
example in the reference manual)
To support these new features, this commit also includes the following
changes.
- The `field` property in BeanOverrideHandler is now @Nullable.
- BeanOverrideProcessor has a new `default` createHandlers() method
which is invoked when a @BeanOverride annotation is found at the
type level.
- MockitoBeanOverrideProcessor implements the new createHandlers()
method.
- The internal findHandlers() method in BeanOverrideHandler has been
completely overhauled.
- The @MockitoBean and @MockitoSpyBean section of the reference
manual has been completely overhauled.
