Prior to this commit, DynamicPropertyRegistry could only be used with a
static @DynamicPropertySource method in an integration test class;
however, it can also be useful to be able to register a "dynamic
property" from within a test's ApplicationContext -- for example, in a
@Bean method in a @Configuration class that is specific to testing
scenarios.
To support such use cases, this commit updates the dynamic property
source infrastructure so that a DynamicPropertyRegistry is always
registered as a singleton bean in a test's ApplicationContext. This
allows DynamicPropertyRegistry to be autowired into a @Configuration
class or supplied to a @Bean method as an argument as shown in the
following example.
@Bean
@DynamicPropertySource
ApiServer apiServer(DynamicPropertyRegistry registry) {
ApiServer apiServer = new ApiServer();
registry.add("api.url", apiServer::getUrl);
return apiServer;
}
Note that the use of @DynamicPropertySource on the @Bean method is
optional and results in the corresponding bean being eagerly
initialized so that other singleton beans in the context can be given
access to the dynamic properties sourced from that bean when those
other beans are initialized.
Side note: DynamicPropertySourceBeanInitializer temporarily implements
LoadTimeWeaverAware since doing so is currently the only way to have a
component eagerly initialized before the
ConfigurableListableBeanFactory.preInstantiateSingletons() phase.
However, we plan to introduce a first-class callback to support such
use cases in the future.

This commit introduces a `isNotEqualTo(String)` assertion in order to
avoid false negatives when using the default Object-based assertion.
This is a risk since MediaTypeAssert has a `isEqualTo(String)` method
that overrides the base object method and parses the provided String
into a MediaType. Users may thus be tempted to use the reverse assertion
and expect the same parsing behaviour.
This commit also adds tests around the String parsing and the isNotEqual
cases.
Closes gh-32756
This change switches default behavior of `@TestBean`, `@MockitoBean` and
`@MockitoSpyBean` to match the bean definition / bean to override by
type in the case there is no explicit bean name provided via the
annotation. The previous behavior of using the annotated field's name
is still an option for implementors, but no longer the default.
Closes gh-32761
Prior to this commit, trailing slash matching was disabled by default in
Spring MVC with gh-28552. `StandaloneMockMvcBuilder` was not changed as
a result and still had the trailing slash match option enabled.
This commit aligns the defaults in `StandaloneMockMvcBuilder` to better
reflect the expected behavior in tests.
Closes gh-32796
This commit renames AssertableMockMvc to MockMvcTester as the former
was too mouthful, and we are looking for a naming pattern that can be
applied consistently to test utilities that rely on AssertJ.
Rather than AssertableMvcResult, we now use MvcTestResult and it no
longer extends from MvcResult itself. That avoids having existing code
that is migrated to the new API whilst assigning the result to MvcResult
and get a bad DevXP as that doesn't bring any of the AssertJ support.
See gh-32712
This commit removes ResponseBodyAssert and rather offers first-class
access support for the response body at the root level using bodyText(),
bodyJson(), and body().
This avoids a double navigation to assert the response body.
See gh-32712
This commit merges the JSONCompare and JsonPath support in a single
assert object. The rationale for the previous situation was that
JsonPath is optional but merging the assertions methods do not make
it mandatory as the usage if JsonPath is triggered only if it is
actually used.
See gh-32712
This commit improves on the bean overriding feature in several ways:
the API is simplified and polished (metadata and processor contracts,
etc...).
The commit also reworks infrastructure classes (context customizer,
test execution listener, BeanOverrideBeanFactoryPostProcessor, etc...).
Parsing of annotations is now fully stateless.
In order to avoid OverrideMetadata in bean definition and to make a
first step towards AOT support, the BeanOverrideBeanFactoryPostProcessor
now delegates to a BeanOverrideRegistrar to track classes to parse,
the metadata-related state as well as for the field injection methods
for tests.
Lastly, this commit increases the test coverage for the provided
annotations and adds integration tests and fixes a few `@TestBean`
issues.
The ApplicationContext has a resource cache that it uses while the
context is being refreshed. Once the refresh phase completes, the
cache is cleared as its content is no longer in use. If beans are
lazily initialized, there is a case where the cache might be filled
again as processing is deferred past the refresh phase.
For those cases, the cache is not cleared. This can be a problem when
running in this mode with a large set of test configurations as the TCF
caches the related contexts.
This commit includes an additional TestExecutionListener to the TCF that
clears the resource cache if necessary once a test class completes. It
is ordered so that it runs after `@DirtiesContext` support as marking
the context as dirty will remove it from the cache and make that extra
step unnecessary.

This commit adds a new way to use MockMvc by returning a MvcResult that
is AssertJ compatible. Compared to the existing MockMvc infrastructure,
this new model has the following advantages:
* Can be created from a MockMvc instance
* Dedicated builder methods for easier setup
* Assertions use familiar AssertJ syntax with discoverable assertions
through a DSL
* Improved exception message

This commit adds AssertJ compatible assertions for HTTP request and
responses, including headers, media type, and response body. The latter
delegate to the recently included JSON assert support.

Historically, we have rarely intentionally thrown a
NullPointerException in the Spring Framework. Instead, we prefer to
throw either an IllegalArgumentException or IllegalStateException
instead of a NullPointerException.
However, changes to the code in recent times have introduced the use of
Objects.requireNonNull(Object) which throws a NullPointerException
without an explicit error message.
The latter ends up providing less context than a NullPointerException
thrown by the JVM (since Java 14) due to actually de-referencing a
null-pointer. See https://openjdk.org/jeps/358.
In light of that, this commit revises our current use of
Objects.requireNonNull(Object) by removing it or replacing it with
Assert.notNull().
However, we still use Objects.requireNonNull(T, String) in a few places
where we are required to throw a NullPointerException in order to
comply with a third-party contract such as Reactive Streams.
