Prior to this commit, `MockMvc` would support checking for the Servlet
error message as the "response status reason". While this error message
can be driven with the `@ResponseStatus` annotation, this message is not
technically the HTTP status reason listed on the response status line.
This message is provided by the Servlet container in the error page when
the `response.sendError(int, String)` method is used.
This commit adds the missing
`mvc.get().uri("/error/message")).hasErrorMessage("error message")`
assertion to check for this Servlet error message.

It is currently possible for one Bean Override to override another
logically equivalent Bean Override.
For example, a @TestBean can override a @MockitoBean, and vice versa.
In fact, it's also possible for a @MockitoBean to override another
@MockitoBean, for a @TestBean to override a @TestBean, etc.
However, there may be viable use cases for one override overriding
another override. For example, one may have a need to spy on a bean
created by a @TestBean factory method.
In light of that, we do not prohibit one Bean Override from overriding
another Bean Override; however, with this commit we now log a warning
to help developers diagnose issues in case such an override is
unintentional.
For example, given the following test class, where TestConfig registers
a single bean of type MyService named "myService"...
@SpringJUnitConfig(TestConfig.class)
class MyTests {
@TestBean(methodName = "example.TestUtils#createMyService")
MyService testService;
@MockitoBean
MyService mockService;
@Test
void test() {
// ...
}
}
... running that test class results in a log message similar to the
following, which has been formatted for readability.
WARN - Bean with name 'myService' was overridden by multiple handlers:
[
[TestBeanOverrideHandler@44b21f9f
field = example.MyService example.MyTests.testService,
beanType = example.MyService,
beanName = [null],
strategy = REPLACE_OR_CREATE
],
[MockitoBeanOverrideHandler@7ee8130e
field = example.MyService example.MyTests.mockService,
beanType = example.MyService,
beanName = [null],
strategy = REPLACE_OR_CREATE,
reset = AFTER,
extraInterfaces = set[[empty]],
answers = RETURNS_DEFAULTS, serializable = false
]
]
NOTE: The last registered BeanOverrideHandler wins. In the above
example, that means that @MockitoBean overrides @TestBean, resulting
in a Mockito mock for the MyService bean in the test's
ApplicationContext.
Closes gh-34056
Prior to this commit, the Bean Override feature in the Spring
TestContext Framework (for annotations such as @MockitoBean and
@TestBean) silently allowed one bean override to override another
"identical" bean override; however, Spring Boot's @MockBean and
@SpyBean support preemptively rejects identical overrides and throws
an IllegalStateException to signal the configuration error to the user.
To align with the behavior of @MockBean and @SpyBean in Spring Boot,
and to help developers avoid scenarios that are potentially confusing
or difficult to debug, this commit rejects identical bean overrides in
the Spring TestContext Framework.
Note, however, that it is still possible for a bean override to
override a logically equivalent bean override. For example, a
@TestBean can override a @MockitoBean, and vice versa.
Closes gh-34054
To make an analogy to read phenomena for transactional databases, this
commit effectively fixes the "Phantom Read" problem for Bean Overrides.
A phantom read occurs when the BeanOverrideBeanFactoryPostProcessor
retrieves a set of bean names by-type twice and a new bean definition
for a compatible type has been created in the BeanFactory by a
BeanOverrideHandler between the first and second retrieval.
Continue reading for the details...
Prior to this commit, the injection of test Bean Overrides (for
example, when using @MockitoBean) could fail in certain scenarios if
overrides were created for nonexistent beans "by type" without an
explicit name or qualifier. Specifically, if an override for a SubType
was created first, and subsequently an attempt was made to create an
override for a SuperType (where SubType extends SuperType), the
override for the SuperType would "override the override" for the
SubType, effectively removing the override for the SubType.
Consequently, injection of the override instance into the SubType field
would fail with an error message similar to the following.
BeanNotOfRequiredTypeException: Bean named 'Subtype#0' is expected to
be of type 'Subtype' but was actually of type 'Supertype$Mock$XHb7Aspo'
This commit addresses this issue by tracking all generated bean names
(in a generatedBeanNames set) and ensuring that a new bean override
instance is created for the current BeanOverrideHandler if a previous
BeanOverrideHandler already created a bean override instance that now
matches the type required by the current BeanOverrideHandler.
In other words, if the generatedBeanNames set already contains the
beanName that we just found by-type, we cannot "override the override",
because we would lose one of the overrides. Instead, we must create a
new override for the current handler. In the example given above, we
must end up with overrides for both SuperType and SubType.
Closes gh-34025
Commit 6c2cba5d8a introduced a regression by inadvertently removing the
MockReset strategy comparison when resetting @MockitoBean and
@MockitoSpyBean mocks.
This commit reinstates the MockReset strategy check and introduces
tests for this feature.
Closes gh-33941
This commit makes it clear that there are no visibility requirements
for @TestBean fields or factory methods as well as @MockitoBean or
@MockitoSpyBean fields.
Closes gh-33923
This commit introduces a TestBeanReflectiveProcessor that registers
GraalVM native image reflection hints for a fully-qualified method name
configured via @TestBean.
Closes gh-33836
Prior to this commit, the static factory methods in MockReset (such as
MockReset.before() and MockReset.after()) could only be applied to
beans within the ApplicationContext if the test class declared at least
one field annotated with either @MockitoBean or @MockitoSpyBean.
However, the Javadoc states that it should be possible to apply
MockReset directly to any mock in the ApplicationContext using the
static methods in MockReset.
To address that, this commit reworks the "enabled" logic in
MockitoResetTestExecutionListener as follows.
- We no longer check for the presence of annotations from the
org.springframework.test.context.bean.override.mockito package to
determine if MockReset is enabled.
- Instead, we now rely on a new isEnabled() method to determine if
MockReset is enabled.
The logic in the isEnabled() method still relies on the mockitoPresent
flag as an initial check; however, mockitoPresent only determines if
Mockito is present in the classpath. It does not determine if Mockito
can actually be used. For example, it does not detect if the necessary
reachability metadata has been registered to use Mockito within a
GraalVM native image.
To address that last point, the isEnabled() method performs an
additional check to determine if Mockito can be used in the current
environment. Specifically, it invokes Mockito.mockingDetails().isMock()
which in turn initializes core Mockito classes without actually
attempting to create a mock. If that fails, that means that Mockito
cannot actually be used in the current environment, which typically
indicates that GraalVM reachability metadata has not been registered
for the org.mockito.plugins.MockMaker in use (such as the
ProxyMockMaker).
In addition, isEnabled() lazily determines if Mockito can be
initialized, since attempting to detect that during static
initialization results in a GraalVM native image error stating that
Mockito internals were "unintentionally initialized at build time".
If Mockito cannot be initialized, MockitoResetTestExecutionListener
logs a DEBUG level message providing access to the corresponding stack
trace, and MockReset support is disabled.
Closes gh-33829
Spring Boot has honored @Primary for selecting which candidate bean
@MockBean and @SpyBean should mock or spy since Spring Boot 1.4.3;
however, the support for @Primary was not ported from Spring Boot to
Spring Framework's new Bean Overrides feature in the TestContext
framework.
To address that, this commit introduces support for @Primary for
selecting bean overrides -- for example, for annotations such as
@TestBean, @MockitoBean, and @MockitoSpyBean.

Closes gh-33819
Previously, we only looked at the OBJECT_TYPE_ATTRIBUTE on a
FactoryBean's bean definition; however this does not work for
situations where the information is provided by the definition's target
type rather than the attribute.
Rather than manually considering the target type in addition to the
existing consideration of the attribute, we now ask the BeanFactory for
the type that will be produced by the FactoryBean instead.
See https://github.com/spring-projects/spring-boot/issues/40234

In gh-33602, we introduced strict singleton enforcement for bean
overrides -- for example, for @MockitoBean, @TestBean, etc. However,
the use of BeanFactory#isSingleton(beanName) can result in a
BeanCreationException for certain beans, such as a Spring Data JPA
FactoryBean for a JpaRepository.
In light of that, this commit relaxes the singleton enforcement in
BeanOverrideBeanFactoryPostProcessor by only checking the result of
BeanDefinition#isSingleton() for existing bean definitions.
This commit also updates the Javadoc and reference documentation to
reflect the status quo.
See gh-33602
Closes gh-33800
This commit removes the proxyTargetAware attribute from @MockitoSpyBean
while keeping the underlying feature in tact (i.e., transparent
verification for spies created via @MockitoSpyBean).
Closes gh-33775
Prior to this commit, SpringAopBypassingVerificationStartedListener
provided partial support for transparent verification for Mockito spies
created via @MockitoSpyBean when the spy is wrapped in a Spring AOP
proxy. However, attempting to actually verify invocations for a spy
resulted in an exception from Mockito since MockUtil.isMock() returned
false in such scenarios.
This commit addresses that by introducing a SpringMockResolver that
resolves mocks by walking the Spring AOP proxy chain until the target
or a non-static proxy is found.
SpringMockResolver is automatically registered whenever the spring-test
JAR is on the classpath, allowing Mockito to transparently resolve mocks
wrapped in Spring AOP proxies.
Closes gh-33774
Prior to this commit, OverrideMetadata was the only public type in the
org.springframework.test.context.bean.override package whose name did
not start with BeanOverride. In addition, an OverrideMetadata component
plays multiple roles in addition to serving as a holder for metadata.
This commit therefore renames OverrideMetadata to BeanOverrideHandler.
In addition, this commit updates the affected documentation and renames
the following related methods in the Bean Override support.
- BeanOverrideHandler: createOverride() -> createOverrideInstance()
- BeanOverrideHandler: track() -> trackOverrideInstance()
- BeanOverrideProcessor: createMetadata() -> createHandler()
- BeanOverrideContextCustomizer: getMetadata() -> getBeanOverrideHandlers()
- BeanOverrideRegistrar: registerNameForMetadata() -> registerBeanOverrideHandler()
- BeanOverrideRegistrar: markWrapEarly() -> registerWrappingBeanOverrideHandler()
Closes gh-33702
This change remove the support for Mockito annotations, `MockitoSession`
and opening/closing of mocks that was inherited from Boot's `@MockBean`
support, as well as the switch to `MockitoSession` made in 1c893e6.
Attempting to take responsability for things Mockito's own JUnit
Jupiter extension does better is not ideal, and we found it leads to
several corner cases which make `SpringExtension` and `MockitoExtension`
incompatible in the current approach.
Instead, this change refocuses our Mockito bean overriding support
exclusively on aspects specific to the Framework. `MockitoExtension`
will thus be usable in conjunction with `SpringExtension` if one needs
to use `@Captor`/`@InitMocks`/`@Mock`/`@Spy` or other Mockito utilities.
See gh-33318
Closes gh-33692
Prior to this commit, the MockitoResetTestExecutionListener failed to
reset mocks created via @MockitoBean if the @MockitoBean field was
declared in an enclosing class for a @Nested test class. In addition,
the MockitoSession was not properly managed by the
MockitoTestExecutionListener.
This commit addresses those issue as follows.
1) The hasMockitoAnnotations() utility method has been overhauled so
that it finds Mockito annotations not only on the current test class
and on fields of the current test class but also on interfaces,
superclasses, and enclosing classes for @Nested test classes as well
as on fields of superclasses and enclosing classes.
That allows the MockitoResetTestExecutionListener to properly detect
that it needs to reset mocks for fields declared in enclosing classes
for @Nested classes.
2) MockitoTestExecutionListener has been revised so that it only
initializes a MockitoSession before each test method and closes the
MockitoSession after each test method. In addition, it now only manages
the MockitoSession when hasMockitoAnnotations() returns true for the
current test class (which may be a @Nested test class). Furthermore,
it no longer attempts to initialize a MockitoSession during the
prepareTestInstance() callback since that results in an
UnfinishedMockingSessionException for a @Nested test class due to the
fact that a MockitoSession was already created for the current thread
for the enclosing test class.
Closes gh-33676
This commit improves the user experience for common use cases by
introducing new `value` attributes in @MockitoBean and
@MockitoSpyBean that are aliases for the existing `name` attributes.
For example, this allows developers to declare
@MockitoBean("userService") instead of @MockitoBean(name =
"userService"), analogous to the existing name/value alias support in
@TestBean.
