Prior to this commit, ApplicationContext caching support was broken if
two Bean Override fields declared the same annotations but in a
different order.
This commit fixes that by switching to Set semantics for the
annotations declared on a Bean Override field.

Prior to this commit, BeanOverrideBeanFactoryPostProcessor replaced
existing bean definitions with "pseudo" bean definitions; however, that
is unnecessary. An existing BeanDefinition is suitable as-is and does
not need to be replaced with a pseudo/fake definition.
To address that, this commit reregisters an existing bean definition
and only registers a new bean definition when creating a bean
definition for a nonexistent bean.
As a side effect, we no longer need to copy primary and fallback flags.
Closes gh-33627
Prior to this commit, @MockitoBean could be used to either create or
replace a bean definition, but @TestBean could only be used to replace
a bean definition.
However, Bean Override implementations should require the presence of
an existing bean definition by default (i.e. literally "override" by
default), while giving the user the option to have a new bean
definition created if desired.
To address that, this commit introduces a new `enforceOverride`
attribute in @TestBean and @MockitoBean that defaults to true but
allows the user to decide if it's OK to create a bean for a nonexistent
bean definition.
Closes gh-33613
Prior to this commit, a non-singleton FactoryBean was silently replaced
by a singleton bean. In addition, bean definitions for prototype-scoped
and custom-scoped beans were replaced by singleton bean definitions
that were incapable of creating the desired bean instance. For example,
if the bean type of the original bean definition was a concrete class,
an attempt was made to invoke the default constructor which either
succeeded with undesirable results or failed with an exception if the
bean type did not have a default constructor. If the bean type of the
original bean definition was an interface or a FactoryBean that claimed
to create a bean of a certain interface type, an attempt was made to
instantiate the interface which always failed with a
BeanCreationException.
To address the aforementioned issues, this commit reworks the logic in
BeanOverrideBeanFactoryPostProcessor so that an exception is thrown
whenever an attempt is made to override a non-singleton bean.
Closes gh-33602
The tests introduced in this commit reveal the following issues in our
Bean Override support.
- If a FactoryBean signals it does not manage a singleton, the Bean
Override support silently replaces it with a singleton.
- An attempt to override a prototype-scoped bean or a bean configured
with a custom scope results in one of the following.
- If the bean type of the original bean definition is a concrete
class, an attempt will be made to invoke the default constructor
which will either succeed with undesirable results or fail with an
exception if the bean type does not have a default constructor.
- If the bean type of the original bean definition is an interface or
a FactoryBean that claims to create a bean of a certain interface
type, an attempt will be made to instantiate the interface which
will always fail with a BeanCreationException.
In order to allow third parties (for example, Spring Boot) to ensure
that a DynamicPropertyRegistrarBeanInitializer has been registered in
an ApplicationContext which has not been customized by the
DynamicPropertiesContextCustomizer, this commit converts
DynamicPropertyRegistrarBeanInitializer to a public API for use in such
special use cases.
Closes gh-33593
This commit introduces example support for a custom @EasyMockBean
annotation that allows tests to use EasyMock as the mocking framework
for bean overrides in a test's ApplicationContext.
The point of this exercise is to ensure that it is possible for third
parties to introduce bean override support for mocking frameworks other
than Mockito, and that they can do so with the APIs currently in place.
Closes gh-33562
Spring Boot's testing support registers a DynamicPropertyRegistry as a
bean in the ApplicationContext, which conflicts with the
DynamicPropertyRegistry registered as a bean by the Spring TestContext
Framework (TCF) since Spring Framework 6.2 M2.
To avoid that conflict and to improve the user experience for Spring's
testing support, this commit introduces a DynamicPropertyRegistrar API
to replace the DynamicPropertyRegistry bean support.
Specifically, the TCF no longer registers a DynamicPropertyRegistry as
a bean in the ApplicationContext.
Instead, users can now register custom implementations of
DynamicPropertyRegistrar as beans in the ApplicationContext, and the
DynamicPropertiesContextCustomizer now registers a
DynamicPropertyRegistrarBeanInitializer which eagerly initializes
DynamicPropertyRegistrar beans and invokes their accept() methods with
an appropriate DynamicPropertyRegistry.
In addition, a singleton DynamicValuesPropertySource is created and
registered with the Environment for use in
DynamicPropertiesContextCustomizer and
DynamicPropertyRegistrarBeanInitializer, which allows
@DynamicPropertySource methods and DynamicPropertyRegistrar beans to
transparently populate the same DynamicValuesPropertySource.
Closes gh-33501
This commit exposes the unexpanded URI template used to build a
MockHttpServletRequest. This allows MockMvc users to retrieve that
information, in consistency with ExchangeResult in WebTestClient.
Closes gh-33509
Prior to this commit, when ReflectionTestUtils was used to invoke a
method on a CGLIB proxy, the invocation was always performed directly
on the proxy. Consequently, if the method was not proxied/intercepted
by the CGLIB proxy -- for example, if the method was final or
effectively private -- the invoked method could not operate on the
state of the target object or interact with other private methods in
the target object.
With this commit, if the supplied target object is a CGLIB proxy which
does not intercept the method, the proxy will be unwrapped allowing the
method to be invoked directly on the ultimate target of the proxy.
Closes gh-33429
This commit applies the same kind of processing for
Void.class element type in the ParameterizedTypeReference
variant of WebTestClient.ResponseSpec#returnResult than
in the Class variant.
Closes gh-33389
