-### RuntimeHints Java Agent
-
-The `spring-core-test` project module contributes the `RuntimeHintsAgent` Java agent.
-
-The `RuntimeHintsAgentPlugin` Gradle plugin creates a dedicated `"runtimeHintsTest"` test task for each project.
-This task will detect and execute [tests tagged](https://junit.org/junit5/docs/current/user-guide/#running-tests-build-gradle)
-with the `"RuntimeHintsTests"` [JUnit tag](https://junit.org/junit5/docs/current/user-guide/#running-tests-tags).
-In the Spring Framework test suite, those are usually annotated with the `@EnabledIfRuntimeHintsAgent` annotation.
-
-By default, the agent will instrument all classes located in the `"org.springframework"` package, as they are loaded.
-The `RuntimeHintsAgentExtension` allows to customize this using a DSL:
-
-```groovy
-// this applies the `RuntimeHintsAgentPlugin` to the project
-plugins {
-	id 'org.springframework.build.runtimehints-agent'
-}
-
-// You can configure the agent to include and exclude packages from the instrumentation process.
-runtimeHintsAgent {
-	includedPackages = ["org.springframework", "io.spring"]
-	excludedPackages = ["org.example"]
-}
-
-dependencies {
-    // to use the test infrastructure, the project should also depend on the "spring-core-test" module
-	testImplementation(project(":spring-core-test"))
-}
-```
-
-With this configuration, `./gradlew runtimeHintsTest` will run all tests instrumented by this java agent.
-The global `./gradlew check` task depends on `runtimeHintsTest`.            
-
-NOTE: the "spring-core-test" module doesn't shade "spring-core" by design, so the agent should never instrument
-code that doesn't have "spring-core" on its classpath.

-= Ahead of Time Optimizations
-
-This chapter covers Spring's Ahead of Time (AOT) optimizations.
-
-For AOT support specific to integration tests, see <<testing.adoc#testcontext-aot, Ahead of Time Support for Tests>>.
-
-[[core.aot.introduction]]
-== Introduction to Ahead of Time Optimizations
-
-Spring's support for AOT optimizations is meant to inspect an `ApplicationContext` at build time and apply decisions and discovery logic that usually happens at runtime.
-Doing so allows building an application startup arrangement that is more straightforward and focused on a fixed set of features based mainly on the classpath and the `Environment`.
-
-Applying such optimizations early implies the following restrictions:
-
-* The classpath is fixed and fully defined at build time.
-* The beans defined in your application cannot change at runtime, meaning:
-** `@Profile`, in particular profile-specific configuration needs to be chosen at build time.
-** Environment properties that impact the presence of a bean (`@Conditional`) are only considered at build time.
-
-When these restrictions are in place, it becomes possible to perform ahead-of-time processing at build time and generate additional assets.
-A Spring AOT processed application typically generates:
-
-* Java source code
-* Bytecode (usually for dynamic proxies)
-* {api-spring-framework}/aot/hint/RuntimeHints.html[`RuntimeHints`] for the use of reflection, resource loading, serialization, and JDK proxies.
-
-NOTE: At the moment, AOT is focused on allowing Spring applications to be deployed as native images using GraalVM.
-We intend to support more JVM-based use cases in future generations.
-
-[[core.aot.basics]]
-== AOT engine overview
-
-The entry point of the AOT engine for processing an `ApplicationContext` arrangement is `ApplicationContextAotGenerator`. It takes care of the following steps, based on a `GenericApplicationContext` that represents the application to optimize and a {api-spring-framework}/aot/generate/GenerationContext.html[`GenerationContext`]:
-
-* Refresh an `ApplicationContext` for AOT processing. Contrary to a traditional refresh, this version only creates bean definitions, not bean instances.
-* Invoke the available `BeanFactoryInitializationAotProcessor` implementations and apply their contributions against the `GenerationContext`.
-For instance, a core implementation iterates over all candidate bean definitions and generates the necessary code to restore the state of the `BeanFactory`.
-
-Once this process completes, the `GenerationContext` will have been updated with the generated code, resources, and classes that are necessary for the application to run.
-The `RuntimeHints` instance can also be used to generate the relevant GraalVM native image configuration files.
-
-`ApplicationContextAotGenerator#processAheadOfTime` returns the class name of the `ApplicationContextInitializer` entry point that allows the context to be started with AOT optimizations.
-
-Those steps are covered in greater detail in the sections below.
-
-[[core.aot.refresh]]
-== Refresh for AOT Processing
-
-Refresh for AOT processing is supported on all `GenericApplicationContext` implementations.
-An application context is created with any number of entry points, usually in the form of `@Configuration`-annotated classes.
-
-Let's look at a basic example:
-
-include::code:AotProcessingSample[tag=myapplication]
-
-Starting this application with the regular runtime involves a number of steps including classpath scanning, configuration class parsing, bean instantiation, and lifecycle callback handling.
-Refresh for AOT processing only applies a subset of what happens with a <<beans-introduction,regular `refresh`>>.
-AOT processing can be triggered as follows:
-
-include::code:AotProcessingSample[tag=aotcontext]
-
-In this mode, <<beans-factory-extension-factory-postprocessors,`BeanFactoryPostProcessor` implementations>> are invoked as usual.
-This includes configuration class parsing, import selectors, classpath scanning, etc.
-Such steps make sure that the `BeanRegistry` contains the relevant bean definitions for the application.
-If bean definitions are guarded by conditions (such as `@Profile`), these are discarded at this stage.
-
-Because this mode does not actually create bean instances, `BeanPostProcessor` implementations are not invoked, except for specific variants that are relevant for AOT processing.
-These are:
-
-* `MergedBeanDefinitionPostProcessor` implementations post-process bean definitions to extract additional settings, such as `init` and `destroy` methods.
-* `SmartInstantiationAwareBeanPostProcessor` implementations determine a more precise bean type if necessary.
-This makes sure to create any proxy that will be required at runtime.
-
-One this part completes, the `BeanFactory` contains the bean definitions that are necessary for the application to run. It does not trigger bean instantiation but allows the AOT engine to inspect the beans that will be created at runtime.
-
-[[core.aot.bean-factory-initialization-contributions]]
-== Bean Factory Initialization AOT Contributions
-
-Components that want to participate in this step can implement the {api-spring-framework}/beans/factory/aot/BeanFactoryInitializationAotProcessor.html[`BeanFactoryInitializationAotProcessor`] interface.
-Each implementation can return an AOT contribution, based on the state of the bean factory.
-
-An AOT contribution is a component that contributes generated code that reproduces a particular behavior.
-It can also contribute `RuntimeHints` to indicate the need for reflection, resource loading, serialization, or JDK proxies.
-
-A `BeanFactoryInitializationAotProcessor` implementation can be registered in `META-INF/spring/aot.factories` with a key equal to the fully qualified name of the interface.
-
-A `BeanFactoryInitializationAotProcessor` can also be implemented directly by a bean.
-In this mode, the bean provides an AOT contribution equivalent to the feature it provides with a regular runtime.
-Consequently, such a bean is automatically excluded from the AOT-optimized context.
-
-[NOTE]
-====
-If a bean implements the `BeanFactoryInitializationAotProcessor` interface, the bean and **all** of its dependencies will be initialized during AOT processing.
-We generally recommend that this interface is only implemented by infrastructure beans such as `BeanFactoryPostProcessor` which have limited dependencies and are already initialized early in the bean factory lifecycle.
-If such a bean is registered using an `@Bean` factory method, ensure the method is `static` so that its enclosing `@Configuration` class does not have to be initialized.
-====
-
-
-[[core.aot.bean-registration-contributions]]
-=== Bean Registration AOT Contributions
-
-A core `BeanFactoryInitializationAotProcessor` implementation is responsible for collecting the necessary contributions for each candidate `BeanDefinition`.
-It does so using a dedicated `BeanRegistrationAotProcessor`.
-
-This interface is used as follows:
-
-* Implemented by a `BeanPostProcessor` bean, to replace its runtime behavior.
-For instance <<beans-factory-extension-bpp-examples-aabpp,`AutowiredAnnotationBeanPostProcessor`>> implements this interface to generate code that injects members annotated with `@Autowired`.
-* Implemented by a type registered in `META-INF/spring/aot.factories` with a key equal to the fully qualified name of the interface.
-Typically used when the bean definition needs to be tuned for specific features of the core framework.
-
-[NOTE]
-====
-If a bean implements the `BeanRegistrationAotProcessor` interface, the bean and **all** of its dependencies will be initialized during AOT processing.
-We generally recommend that this interface is only implemented by infrastructure beans such as `BeanFactoryPostProcessor` which have limited dependencies and are already initialized early in the bean factory lifecycle.
-If such a bean is registered using an `@Bean` factory method, ensure the method is `static` so that its enclosing `@Configuration` class does not have to be initialized.
-====
-
-If no `BeanRegistrationAotProcessor` handles a particular registered bean, a default implementation processes it.
-This is the default behavior, since tuning the generated code for a bean definition should be restricted to corner cases.
-
-Taking our previous example, let's assume that `DataSourceConfiguration` is as follows:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	@Configuration(proxyBeanMethods = false)
-	public class DataSourceConfiguration {
-
-		@Bean
-		public SimpleDataSource dataSource() {
-			return new SimpleDataSource();
-		}
-
-	}
----
-
-Since there isn't any particular condition on this class, `dataSourceConfiguration` and `dataSource` are identified as candidates.
-The AOT engine will convert the configuration class above to code similar to the following:
-
-[source,java,indent=0,role="primary"]
-.Java
----
-	/**
-	 * Bean definitions for {@link DataSourceConfiguration}
-	 */
-	public class DataSourceConfiguration__BeanDefinitions {
-		/**
-		 * Get the bean definition for 'dataSourceConfiguration'
-		 */
-		public static BeanDefinition getDataSourceConfigurationBeanDefinition() {
-			Class<?> beanType = DataSourceConfiguration.class;
-			RootBeanDefinition beanDefinition = new RootBeanDefinition(beanType);
-			beanDefinition.setInstanceSupplier(DataSourceConfiguration::new);
-			return beanDefinition;
-		}
-
-		/**
-		 * Get the bean instance supplier for 'dataSource'.
-		 */
-		private static BeanInstanceSupplier<SimpleDataSource> getDataSourceInstanceSupplier() {
-			return BeanInstanceSupplier.<SimpleDataSource>forFactoryMethod(DataSourceConfiguration.class, "dataSource")
-					.withGenerator((registeredBean) -> registeredBean.getBeanFactory().getBean(DataSourceConfiguration.class).dataSource());
-		}
-
-		/**
-		 * Get the bean definition for 'dataSource'
-		 */
-		public static BeanDefinition getDataSourceBeanDefinition() {
-			Class<?> beanType = SimpleDataSource.class;
-			RootBeanDefinition beanDefinition = new RootBeanDefinition(beanType);
-			beanDefinition.setInstanceSupplier(getDataSourceInstanceSupplier());
-			return beanDefinition;
-		}
-	}
----
-
-NOTE: The exact code generated may differ depending on the exact nature of your bean definitions.
-
-The generated code above creates bean definitions equivalent to the `@Configuration` class, but in a direct way and without the use of reflection if at all possible.
-There is a bean definition for `dataSourceConfiguration` and one for `dataSourceBean`.
-When a `datasource` instance is required, a `BeanInstanceSupplier` is called.
-This supplier invokes the `dataSource()` method on the `dataSourceConfiguration` bean.
-
-
-[[core.aot.hints]]
-== Runtime Hints
-
-Running an application as a native image requires additional information compared to a regular JVM runtime.
-For instance, GraalVM needs to know ahead of time if a component uses reflection.
-Similarly, classpath resources are not shipped in a native image unless specified explicitly.
-Consequently, if the application needs to load a resource, it must be referenced from the corresponding GraalVM native image configuration file.
-
-The {api-spring-framework}/aot/hint/RuntimeHints.html[`RuntimeHints`] API collects the need for reflection, resource loading, serialization, and JDK proxies at runtime.
-The following example makes sure that `config/app.properties` can be loaded from the classpath at runtime within a native image:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	runtimeHints.resources().registerPattern("config/app.properties");
----
-
-A number of contracts are handled automatically during AOT processing.
-For instance, the return type of a `@Controller` method is inspected, and relevant reflection hints are added if Spring detects that the type should be serialized (typically to JSON).
-
-For cases that the core container cannot infer, you can register such hints programmatically.
-A number of convenient annotations are also provided for common use cases.
-
-
-[[core.aot.hints.import-runtime-hints]]
-=== `@ImportRuntimeHints`
-
-`RuntimeHintsRegistrar` implementations allow you to get a callback to the `RuntimeHints` instance managed by the AOT engine.
-Implementations of this interface can be registered using `@ImportRuntimeHints` on any Spring bean or `@Bean` factory method.
-`RuntimeHintsRegistrar` implementations are detected and invoked at build time.
-
-include::code:SpellCheckService[]
-
-If at all possible, `@ImportRuntimeHints` should be used as close as possible to the component that requires the hints.
-This way, if the component is not contributed to the `BeanFactory`, the hints won't be contributed either.
-
-It is also possible to register an implementation statically by adding an entry in `META-INF/spring/aot.factories` with a key equal to the fully qualified name of the `RuntimeHintsRegistrar` interface.
-
-
-[[core.aot.hints.reflective]]
-=== `@Reflective`
-
-{api-spring-framework}/aot/hint/annotation/Reflective.html[`@Reflective`] provides an idiomatic way to flag the need for reflection on an annotated element.
-For instance, `@EventListener` is meta-annotated with `@Reflective` since the underlying implementation invokes the annotated method using reflection.
-
-By default, only Spring beans are considered and an invocation hint is registered for the annotated element.
-This can be tuned by specifying a custom `ReflectiveProcessor` implementation via the
-`@Reflective` annotation.
-
-Library authors can reuse this annotation for their own purposes.
-If components other than Spring beans need to be processed, a `BeanFactoryInitializationAotProcessor` can detect the relevant types and use `ReflectiveRuntimeHintsRegistrar` to process them.
-
-
-[[core.aot.hints.register-reflection-for-binding]]
-=== `@RegisterReflectionForBinding`
-
-{api-spring-framework}/aot/hint/annotation/RegisterReflectionForBinding.html[`@RegisterReflectionForBinding`] is a specialization of `@Reflective` that registers the need for serializing arbitrary types.
-A typical use case is the use of DTOs that the container cannot infer, such as using a web client within a method body.
-
-`@RegisterReflectionForBinding` can be applied to any Spring bean at the class level, but it can also be applied directly to a method, field, or constructor to better indicate where the hints are actually required.
-The following example registers `Account` for serialization.
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	@Component
-	public class OrderService {
-
-		@RegisterReflectionForBinding(Account.class)
-		public void process(Order order) {
-			// ...
-		}
-
-	}
----
-
-[[core.aot.hints.testing]]
-=== Testing Runtime Hints
-
-Spring Core also ships `RuntimeHintsPredicates`, a utility for checking that existing hints match a particular use case.
-This can be used in your own tests to validate that a `RuntimeHintsRegistrar` contains the expected results.
-We can write a test for our `SpellCheckService` and ensure that we will be able to load a dictionary at runtime:
-
-include::code:SpellCheckServiceTests[tag=hintspredicates]
-
-With `RuntimeHintsPredicates`, we can check for reflection, resource, serialization, or proxy generation hints.
-This approach works well for unit tests but implies that the runtime behavior of a component is well known.
-
-You can learn more about the global runtime behavior of an application by running its test suite (or the app itself) with the {docs-graalvm}/native-image/metadata/AutomaticMetadataCollection/[GraalVM tracing agent].
-This agent will record all relevant calls requiring GraalVM hints at runtime and write them out as JSON configuration files.
-
-For more targeted discovery and testing, Spring Framework ships a dedicated module with core AOT testing utilities, `"org.springframework:spring-core-test"`.
-This module contains the RuntimeHints Agent, a Java agent that records all method invocations that are related to runtime hints and helps you to assert that a given `RuntimeHints` instance covers all recorded invocations.
-Let's consider a piece of infrastructure for which we'd like to test the hints we're contributing during the AOT processing phase.
-
-include::code:SampleReflection[]
-
-We can then write a unit test (no native compilation required) that checks our contributed hints:
-
-include::code:SampleReflectionRuntimeHintsTests[]
-
-If you forgot to contribute a hint, the test will fail and provide some details about the invocation:
-
-[source,txt,indent=0,subs="verbatim,quotes"]
----

----
-
-There are various ways to configure this Java agent in your build, so please refer to the documentation of your build tool and test execution plugin.
-The agent itself can be configured to instrument specific packages (by default, only `org.springframework` is instrumented).

-= Integration Testing
-
-It is important to be able to perform some integration testing without requiring
-deployment to your application server or connecting to other enterprise infrastructure.
-Doing so lets you test things such as:
-
-* The correct wiring of your Spring IoC container contexts.
-* Data access using JDBC or an ORM tool. This can include such things as the correctness
-  of SQL statements, Hibernate queries, JPA entity mappings, and so forth.
-
-The Spring Framework provides first-class support for integration testing in the
-`spring-test` module. The name of the actual JAR file might include the release version
-and might also be in the long `org.springframework.test` form, depending on where you get
-it from (see the <<core.adoc#beans-dependencies, section on Dependency Management>>
-for an explanation). This library includes the `org.springframework.test` package, which
-contains valuable classes for integration testing with a Spring container. This testing
-does not rely on an application server or other deployment environment. Such tests are
-slower to run than unit tests but much faster than the equivalent Selenium tests or
-remote tests that rely on deployment to an application server.
-
-Unit and integration testing support is provided in the form of the annotation-driven
-<<testcontext-framework, Spring TestContext Framework>>. The TestContext framework is
-agnostic of the actual testing framework in use, which allows instrumentation of tests
-in various environments, including JUnit, TestNG, and others.
-
-The following section provides an overview of the high-level goals of Spring's
-integration support, and the rest of this chapter then focuses on dedicated topics:
-
-* <<integration-testing-support-jdbc>>
-* <<testcontext-framework>>
-* <<webtestclient>>
-* <<spring-mvc-test-framework>>
-* <<spring-mvc-test-client>>
-* <<integration-testing-annotations>>
-
-
-
-[[integration-testing-goals]]
-== Goals of Integration Testing
-
-Spring's integration testing support has the following primary goals:
-
-* To manage <<testing-ctx-management, Spring IoC container caching>> between tests.
-* To provide <<testing-fixture-di, Dependency Injection of test fixture instances>>.
-* To provide <<testing-tx, transaction management>> appropriate to integration testing.
-* To supply <<testing-support-classes, Spring-specific base classes>> that assist
-  developers in writing integration tests.
-
-The next few sections describe each goal and provide links to implementation and
-configuration details.
-
-
-[[testing-ctx-management]]
-=== Context Management and Caching
-
-The Spring TestContext Framework provides consistent loading of Spring
-`ApplicationContext` instances and `WebApplicationContext` instances as well as caching
-of those contexts. Support for the caching of loaded contexts is important, because
-startup time can become an issue -- not because of the overhead of Spring itself, but
-because the objects instantiated by the Spring container take time to instantiate. For
-example, a project with 50 to 100 Hibernate mapping files might take 10 to 20 seconds to
-load the mapping files, and incurring that cost before running every test in every test
-fixture leads to slower overall test runs that reduce developer productivity.
-
-Test classes typically declare either an array of resource locations for XML or Groovy
-configuration metadata -- often in the classpath -- or an array of component classes that
-is used to configure the application. These locations or classes are the same as or
-similar to those specified in `web.xml` or other configuration files for production
-deployments.
-
-By default, once loaded, the configured `ApplicationContext` is reused for each test.
-Thus, the setup cost is incurred only once per test suite, and subsequent test execution
-is much faster. In this context, the term "`test suite`" means all tests run in the same
-JVM -- for example, all tests run from an Ant, Maven, or Gradle build for a given project
-or module. In the unlikely case that a test corrupts the application context and requires
-reloading (for example, by modifying a bean definition or the state of an application
-object) the TestContext framework can be configured to reload the configuration and
-rebuild the application context before executing the next test.
-
-See <<testcontext-ctx-management>> and <<testcontext-ctx-management-caching>> with the
-TestContext framework.
-
-
-[[testing-fixture-di]]
-=== Dependency Injection of Test Fixtures
-
-When the TestContext framework loads your application context, it can optionally
-configure instances of your test classes by using Dependency Injection. This provides a
-convenient mechanism for setting up test fixtures by using preconfigured beans from your
-application context. A strong benefit here is that you can reuse application contexts
-across various testing scenarios (for example, for configuring Spring-managed object
-graphs, transactional proxies, `DataSource` instances, and others), thus avoiding the
-need to duplicate complex test fixture setup for individual test cases.
-
-As an example, consider a scenario where we have a class (`HibernateTitleRepository`)
-that implements data access logic for a `Title` domain entity. We want to write
-integration tests that test the following areas:
-
-* The Spring configuration: Basically, is everything related to the configuration of the
-  `HibernateTitleRepository` bean correct and present?
-* The Hibernate mapping file configuration: Is everything mapped correctly and are the
-  correct lazy-loading settings in place?
-* The logic of the `HibernateTitleRepository`: Does the configured instance of this class
-  perform as anticipated?
-
-See dependency injection of test fixtures with the
-<<testcontext-fixture-di, TestContext framework>>.
-
-
-[[testing-tx]]
-=== Transaction Management
-
-One common issue in tests that access a real database is their effect on the state of the
-persistence store. Even when you use a development database, changes to the state may
-affect future tests. Also, many operations -- such as inserting or modifying persistent
-data -- cannot be performed (or verified) outside of a transaction.
-
-The TestContext framework addresses this issue. By default, the framework creates and
-rolls back a transaction for each test. You can write code that can assume the existence
-of a transaction. If you call transactionally proxied objects in your tests, they behave
-correctly, according to their configured transactional semantics. In addition, if a test
-method deletes the contents of selected tables while running within the transaction
-managed for the test, the transaction rolls back by default, and the database returns to
-its state prior to execution of the test. Transactional support is provided to a test by
-using a `PlatformTransactionManager` bean defined in the test's application context.
-
-If you want a transaction to commit (unusual, but occasionally useful when you want a
-particular test to populate or modify the database), you can tell the TestContext
-framework to cause the transaction to commit instead of roll back by using the
-<<integration-testing-annotations, `@Commit`>> annotation.
-
-See transaction management with the <<testcontext-tx, TestContext framework>>.

-[[testing-support-classes]]
-=== Support Classes for Integration Testing
-
-The Spring TestContext Framework provides several `abstract` support classes that
-simplify the writing of integration tests. These base test classes provide well-defined
-hooks into the testing framework as well as convenient instance variables and methods,
-which let you access:
-
-* The `ApplicationContext`, for performing explicit bean lookups or testing the state of
-  the context as a whole.
-* A `JdbcTemplate`, for executing SQL statements to query the database. You can use such
-  queries to confirm database state both before and after execution of database-related
-  application code, and Spring ensures that such queries run in the scope of the same
-  transaction as the application code. When used in conjunction with an ORM tool, be sure
-  to avoid <<testcontext-tx-false-positives, false positives>>.
-
-In addition, you may want to create your own custom, application-wide superclass with
-instance variables and methods specific to your project.
-
-See support classes for the <<testcontext-support-classes, TestContext framework>>.

-= Testing Client Applications
-
-You can use client-side tests to test code that internally uses the `RestTemplate`. The
-idea is to declare expected requests and to provide "`stub`" responses so that you can
-focus on testing the code in isolation (that is, without running a server). The following
-example shows how to do so:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	RestTemplate restTemplate = new RestTemplate();
-
-	MockRestServiceServer mockServer = MockRestServiceServer.bindTo(restTemplate).build();
-	mockServer.expect(requestTo("/greeting")).andRespond(withSuccess());
-
-	// Test code that uses the above RestTemplate ...
-
-	mockServer.verify();
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val restTemplate = RestTemplate()
-
-	val mockServer = MockRestServiceServer.bindTo(restTemplate).build()
-	mockServer.expect(requestTo("/greeting")).andRespond(withSuccess())
-
-	// Test code that uses the above RestTemplate ...
-
-	mockServer.verify()
----
-
-In the preceding example, `MockRestServiceServer` (the central class for client-side REST
-tests) configures the `RestTemplate` with a custom `ClientHttpRequestFactory` that
-asserts actual requests against expectations and returns "`stub`" responses. In this
-case, we expect a request to `/greeting` and want to return a 200 response with
-`text/plain` content. We can define additional expected requests and stub responses as
-needed. When we define expected requests and stub responses, the `RestTemplate` can be
-used in client-side code as usual. At the end of testing, `mockServer.verify()` can be
-used to verify that all expectations have been satisfied.
-
-By default, requests are expected in the order in which expectations were declared. You
-can set the `ignoreExpectOrder` option when building the server, in which case all
-expectations are checked (in order) to find a match for a given request. That means
-requests are allowed to come in any order. The following example uses `ignoreExpectOrder`:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	server = MockRestServiceServer.bindTo(restTemplate).ignoreExpectOrder(true).build();
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	server = MockRestServiceServer.bindTo(restTemplate).ignoreExpectOrder(true).build()
----
-
-Even with unordered requests by default, each request is allowed to run once only.
-The `expect` method provides an overloaded variant that accepts an `ExpectedCount`
-argument that specifies a count range (for example, `once`, `manyTimes`, `max`, `min`,
-`between`, and so on). The following example uses `times`:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	RestTemplate restTemplate = new RestTemplate();
-
-	MockRestServiceServer mockServer = MockRestServiceServer.bindTo(restTemplate).build();
-	mockServer.expect(times(2), requestTo("/something")).andRespond(withSuccess());
-	mockServer.expect(times(3), requestTo("/somewhere")).andRespond(withSuccess());
-
-	// ...
-
-	mockServer.verify();
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val restTemplate = RestTemplate()
-
-	val mockServer = MockRestServiceServer.bindTo(restTemplate).build()
-	mockServer.expect(times(2), requestTo("/something")).andRespond(withSuccess())
-	mockServer.expect(times(3), requestTo("/somewhere")).andRespond(withSuccess())
-
-	// ...
-
-	mockServer.verify()
----
-
-Note that, when `ignoreExpectOrder` is not set (the default), and, therefore, requests
-are expected in order of declaration, then that order applies only to the first of any
-expected request. For example if "/something" is expected two times followed by
-"/somewhere" three times, then there should be a request to "/something" before there is
-a request to "/somewhere", but, aside from that subsequent "/something" and "/somewhere",
-requests can come at any time.
-
-As an alternative to all of the above, the client-side test support also provides a
-`ClientHttpRequestFactory` implementation that you can configure into a `RestTemplate` to
-bind it to a `MockMvc` instance. That allows processing requests using actual server-side
-logic but without running a server. The following example shows how to do so:
-
-[source,java,indent=0,subs="verbatim,quotes",role="primary"]
-.Java
----
-	MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
-	this.restTemplate = new RestTemplate(new MockMvcClientHttpRequestFactory(mockMvc));
-
-	// Test code that uses the above RestTemplate ...
----
-[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
-.Kotlin
----
-	val mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build()
-	restTemplate = RestTemplate(MockMvcClientHttpRequestFactory(mockMvc))
-
-	// Test code that uses the above RestTemplate ...

-[[spring-mvc-test-client-static-imports]]
-== Static Imports
-
-As with server-side tests, the fluent API for client-side tests requires a few static
-imports. Those are easy to find by searching for `MockRest*`. Eclipse users should add
-`MockRestRequestMatchers.{asterisk}` and `MockRestResponseCreators.{asterisk}` as
-"`favorite static members`" in the Eclipse preferences under Java -> Editor -> Content
-Assist -> Favorites. That allows using content assist after typing the first character of
-the static method name. Other IDEs (such IntelliJ) may not require any additional

-[[unit-testing]]
-= Unit Testing
-
-Dependency injection should make your code less dependent on the container than it would
-be with traditional J2EE / Java EE development. The POJOs that make up your application
-should be testable in JUnit or TestNG tests, with objects instantiated by using the `new`
-operator, without Spring or any other container. You can use <<mock-objects, mock objects>>
-(in conjunction with other valuable testing techniques) to test your code in isolation.
-If you follow the architecture recommendations for Spring, the resulting clean layering
-and componentization of your codebase facilitate easier unit testing. For example,
-you can test service layer objects by stubbing or mocking DAO or repository interfaces,
-without needing to access persistent data while running unit tests.
-
-True unit tests typically run extremely quickly, as there is no runtime infrastructure to
-set up. Emphasizing true unit tests as part of your development methodology can boost
-your productivity. You may not need this section of the testing chapter to help you write
-effective unit tests for your IoC-based applications. For certain unit testing scenarios,
-however, the Spring Framework provides mock objects and testing support classes, which
-are described in this chapter.
-
-
-
-[[mock-objects]]
-== Mock Objects
-
-Spring includes a number of packages dedicated to mocking:
-
-* <<mock-objects-env>>
-* <<mock-objects-jndi>>
-* <<mock-objects-servlet>>
-* <<mock-objects-web-reactive>>
-
-
-[[mock-objects-env]]
-=== Environment
-
-The `org.springframework.mock.env` package contains mock implementations of the
-`Environment` and `PropertySource` abstractions (see
-<<core.adoc#beans-definition-profiles, Bean Definition Profiles>>
-and <<core.adoc#beans-property-source-abstraction, `PropertySource` Abstraction>>).
-`MockEnvironment` and `MockPropertySource` are useful for developing
-out-of-container tests for code that depends on environment-specific properties.
-
-
-[[mock-objects-jndi]]
-=== JNDI
-
-The `org.springframework.mock.jndi` package contains a partial implementation of the JNDI
-SPI, which you can use to set up a simple JNDI environment for test suites or stand-alone
-applications. If, for example, JDBC `DataSource` instances get bound to the same JNDI
-names in test code as they do in a Jakarta EE container, you can reuse both application code
-and configuration in testing scenarios without modification.
-
-WARNING: The mock JNDI support in the `org.springframework.mock.jndi` package is
-officially deprecated as of Spring Framework 5.2 in favor of complete solutions from third
-parties such as https://github.com/h-thurow/Simple-JNDI[Simple-JNDI].
-
-
-[[mock-objects-servlet]]
-=== Servlet API
-
-The `org.springframework.mock.web` package contains a comprehensive set of Servlet API
-mock objects that are useful for testing web contexts, controllers, and filters. These
-mock objects are targeted at usage with Spring's Web MVC framework and are generally more
-convenient to use than dynamic mock objects (such as https://easymock.org/[EasyMock])
-or alternative Servlet API mock objects (such as http://www.mockobjects.com[MockObjects]).
-
-TIP: Since Spring Framework 6.0, the mock objects in `org.springframework.mock.web` are
-based on the Servlet 6.0 API.
-
-The Spring MVC Test framework builds on the mock Servlet API objects to provide an
-integration testing framework for Spring MVC. See <<spring-mvc-test-framework>>.
-
-
-[[mock-objects-web-reactive]]
-=== Spring Web Reactive
-
-The `org.springframework.mock.http.server.reactive` package contains mock implementations
-of `ServerHttpRequest` and `ServerHttpResponse` for use in WebFlux applications. The
-`org.springframework.mock.web.server` package contains a mock `ServerWebExchange` that
-depends on those mock request and response objects.
-
-Both `MockServerHttpRequest` and `MockServerHttpResponse` extend from the same abstract
-base classes as server-specific implementations and share behavior with them. For
-example, a mock request is immutable once created, but you can use the `mutate()` method
-from `ServerHttpRequest` to create a modified instance.
-
-In order for the mock response to properly implement the write contract and return a
-write completion handle (that is, `Mono<Void>`), it by default uses a `Flux` with
-`cache().then()`, which buffers the data and makes it available for assertions in tests.
-Applications can set a custom write function (for example, to test an infinite stream).
-
-The <<webtestclient>> builds on the mock request and response to provide support for
-testing WebFlux applications without an HTTP server. The client can also be used for
-end-to-end tests with a running server.

-
-
-[[unit-testing-support-classes]]
-== Unit Testing Support Classes
-
-Spring includes a number of classes that can help with unit testing. They fall into two
-categories:
-
-* <<unit-testing-utilities>>
-* <<unit-testing-spring-mvc>>
-
-
-[[unit-testing-utilities]]
-=== General Testing Utilities
-
-The `org.springframework.test.util` package contains several general purpose utilities
-for use in unit and integration testing.
-
-{api-spring-framework}/test/util/AopTestUtils.html[`AopTestUtils`] is a collection of
-AOP-related utility methods. You can use these methods to obtain a reference to the
-underlying target object hidden behind one or more Spring proxies. For example, if you
-have configured a bean as a dynamic mock by using a library such as EasyMock or Mockito,
-and the mock is wrapped in a Spring proxy, you may need direct access to the underlying
-mock to configure expectations on it and perform verifications. For Spring's core AOP
-utilities, see {api-spring-framework}/aop/support/AopUtils.html[`AopUtils`] and
-{api-spring-framework}/aop/framework/AopProxyUtils.html[`AopProxyUtils`].
-
-{api-spring-framework}/test/util/ReflectionTestUtils.html[`ReflectionTestUtils`] is a
-collection of reflection-based utility methods. You can use these methods in testing
-scenarios where you need to change the value of a constant, set a non-`public` field,
-invoke a non-`public` setter method, or invoke a non-`public` configuration or lifecycle
-callback method when testing application code for use cases such as the following:
-
-* ORM frameworks (such as JPA and Hibernate) that condone `private` or `protected` field
-  access as opposed to `public` setter methods for properties in a domain entity.
-* Spring's support for annotations (such as `@Autowired`, `@Inject`, and `@Resource`),
-  that provide dependency injection for `private` or `protected` fields, setter methods,
-  and configuration methods.
-* Use of annotations such as `@PostConstruct` and `@PreDestroy` for lifecycle callback
-  methods.
-
-{api-spring-framework}/test/util/TestSocketUtils.html[`TestSocketUtils`] is a simple
-utility for finding available TCP ports on `localhost` for use in integration testing
-scenarios.
-
-[NOTE]
-====
-`TestSocketUtils` can be used in integration tests which start an external server on an
-available random port. However, these utilities make no guarantee about the subsequent
-availability of a given port and are therefore unreliable. Instead of using
-`TestSocketUtils` to find an available local port for a server, it is recommended that
-you rely on a server's ability to start on a random ephemeral port that it selects or is
-assigned by the operating system. To interact with that server, you should query the
-server for the port it is currently using.
-====
-
-
-[[unit-testing-spring-mvc]]
-=== Spring MVC Testing Utilities
-
-The `org.springframework.test.web` package contains
-{api-spring-framework}/test/web/ModelAndViewAssert.html[`ModelAndViewAssert`], which you
-can use in combination with JUnit, TestNG, or any other testing framework for unit tests
-that deal with Spring MVC `ModelAndView` objects.
-
-.Unit testing Spring MVC Controllers
-TIP: To unit test your Spring MVC `Controller` classes as POJOs, use `ModelAndViewAssert`
-combined with `MockHttpServletRequest`, `MockHttpSession`, and so on from Spring's
-<<mock-objects-servlet, Servlet API mocks>>. For thorough integration testing of your
-Spring MVC and REST `Controller` classes in conjunction with your `WebApplicationContext`
-configuration for Spring MVC, use the
-<<spring-mvc-test-framework, Spring MVC Test Framework>> instead.

 ## Steps

 _When instructed to execute `./gradlew` from the command line, be sure to execute it within your locally cloned `spring-framework` working directory._

+1. Install the [Groovy Development Tools](https://marketplace.eclipse.org/content/groovy-development-tools).
+1. Switch to Groovy 3.0 in Eclipse (Preferences &#8594; Groovy &#8594; Compiler &#8594; Switch to 3.0...).
+   - If you encounter build errors stating something similar to _"Groovy: compiler mismatch: project level is 2.5, workspace level is 3.0"_, change the Groovy compiler version to 3.0 for each affected project.
 1. Ensure that the _Forbidden reference (access rule)_ in Eclipse is set to `Info`
 (Preferences &#8594; Java &#8594; Compiler &#8594; Errors/Warnings &#8594; Deprecated and restricted API &#8594; Forbidden reference (access rule)).
 1. Optionally install the [Kotlin Plugin for Eclipse](https://marketplace.eclipse.org/content/kotlin-plugin-eclipse) if you need to execute Kotlin-based tests or develop Kotlin extensions.
