= Meta-Annotation Support for Testing

You can use most test-related annotations as
xref:core/beans/classpath-scanning.adoc#beans-meta-annotations[meta-annotations] to create custom composed
annotations and reduce configuration duplication across a test suite.

You can use each of the following as a meta-annotation in conjunction with the
xref:testing/testcontext-framework.adoc[TestContext framework].

* `@BootstrapWith`
* `@ContextConfiguration`
* `@ContextHierarchy`
* `@ContextCustomizerFactories`
* `@ActiveProfiles`
* `@TestPropertySource`
* `@DirtiesContext`
* `@WebAppConfiguration`
* `@TestExecutionListeners`
* `@Transactional`
* `@BeforeTransaction`
* `@AfterTransaction`
* `@Commit`
* `@Rollback`
* `@Sql`
* `@SqlConfig`
* `@SqlMergeMode`
* `@SqlGroup`
* `@Repeat` _(only supported on JUnit 4)_
* `@Timed` _(only supported on JUnit 4)_
* `@IfProfileValue` _(only supported on JUnit 4)_
* `@ProfileValueSourceConfiguration` _(only supported on JUnit 4)_
* `@SpringJUnitConfig` _(only supported on JUnit Jupiter)_
* `@SpringJUnitWebConfig` _(only supported on JUnit Jupiter)_
* `@TestConstructor` _(only supported on JUnit Jupiter)_
* `@NestedTestConfiguration` _(only supported on JUnit Jupiter)_
* `@EnabledIf` _(only supported on JUnit Jupiter)_
* `@DisabledIf` _(only supported on JUnit Jupiter)_

Consider the following example:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	@RunWith(SpringRunner.class)
	@ContextConfiguration({"/app-config.xml", "/test-data-access-config.xml"})
	@ActiveProfiles("dev")
	@Transactional
	public class OrderRepositoryTests { }

	@RunWith(SpringRunner.class)
	@ContextConfiguration({"/app-config.xml", "/test-data-access-config.xml"})
	@ActiveProfiles("dev")
	@Transactional
	public class UserRepositoryTests { }
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	@RunWith(SpringRunner::class)
	@ContextConfiguration("/app-config.xml", "/test-data-access-config.xml")
	@ActiveProfiles("dev")
	@Transactional
	class OrderRepositoryTests { }

	@RunWith(SpringRunner::class)
	@ContextConfiguration("/app-config.xml", "/test-data-access-config.xml")
	@ActiveProfiles("dev")
	@Transactional
	class UserRepositoryTests { }
----

If we discover that we are repeating the preceding configuration across our JUnit 4-based
test suite, we can reduce the duplication by introducing a custom composed annotation
that centralizes the common test configuration for Spring, as follows:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	@Target(ElementType.TYPE)
	@Retention(RetentionPolicy.RUNTIME)
	@ContextConfiguration({"/app-config.xml", "/test-data-access-config.xml"})
	@ActiveProfiles("dev")
	@Transactional
	public @interface TransactionalDevTestConfig { }
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	@Target(AnnotationTarget.TYPE)
	@Retention(AnnotationRetention.RUNTIME)
	@ContextConfiguration("/app-config.xml", "/test-data-access-config.xml")
	@ActiveProfiles("dev")
	@Transactional
	annotation class TransactionalDevTestConfig { }
----
======

Then we can use our custom `@TransactionalDevTestConfig` annotation to simplify the
configuration of individual JUnit 4 based test classes, as follows:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	@RunWith(SpringRunner.class)
	@TransactionalDevTestConfig
	public class OrderRepositoryTests { }

	@RunWith(SpringRunner.class)
	@TransactionalDevTestConfig
	public class UserRepositoryTests { }
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	@RunWith(SpringRunner::class)
	@TransactionalDevTestConfig
	class OrderRepositoryTests

	@RunWith(SpringRunner::class)
	@TransactionalDevTestConfig
	class UserRepositoryTests
----
======

If we write tests that use JUnit Jupiter, we can reduce code duplication even further,
since annotations in JUnit 5 can also be used as meta-annotations. Consider the following
example:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	@ExtendWith(SpringExtension.class)
	@ContextConfiguration({"/app-config.xml", "/test-data-access-config.xml"})
	@ActiveProfiles("dev")
	@Transactional
	class OrderRepositoryTests { }

	@ExtendWith(SpringExtension.class)
	@ContextConfiguration({"/app-config.xml", "/test-data-access-config.xml"})
	@ActiveProfiles("dev")
	@Transactional
	class UserRepositoryTests { }
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	@ExtendWith(SpringExtension::class)
	@ContextConfiguration("/app-config.xml", "/test-data-access-config.xml")
	@ActiveProfiles("dev")
	@Transactional
	class OrderRepositoryTests { }

	@ExtendWith(SpringExtension::class)
	@ContextConfiguration("/app-config.xml", "/test-data-access-config.xml")
	@ActiveProfiles("dev")
	@Transactional
	class UserRepositoryTests { }
----
======

If we discover that we are repeating the preceding configuration across our JUnit
Jupiter-based test suite, we can reduce the duplication by introducing a custom composed
annotation that centralizes the common test configuration for Spring and JUnit Jupiter,
as follows:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	@Target(ElementType.TYPE)
	@Retention(RetentionPolicy.RUNTIME)
	@ExtendWith(SpringExtension.class)
	@ContextConfiguration({"/app-config.xml", "/test-data-access-config.xml"})
	@ActiveProfiles("dev")
	@Transactional
	public @interface TransactionalDevTestConfig { }
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	@Target(AnnotationTarget.TYPE)
	@Retention(AnnotationRetention.RUNTIME)
	@ExtendWith(SpringExtension::class)
	@ContextConfiguration("/app-config.xml", "/test-data-access-config.xml")
	@ActiveProfiles("dev")
	@Transactional
	annotation class TransactionalDevTestConfig { }
----
======

Then we can use our custom `@TransactionalDevTestConfig` annotation to simplify the
configuration of individual JUnit Jupiter based test classes, as follows:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	@TransactionalDevTestConfig
	class OrderRepositoryTests { }

	@TransactionalDevTestConfig
	class UserRepositoryTests { }
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	@TransactionalDevTestConfig
	class OrderRepositoryTests { }

	@TransactionalDevTestConfig
	class UserRepositoryTests { }
----
======

Since JUnit Jupiter supports the use of `@Test`, `@RepeatedTest`, `ParameterizedTest`,
and others as meta-annotations, you can also create custom composed annotations at the
test method level. For example, if we wish to create a composed annotation that combines
the `@Test` and `@Tag` annotations from JUnit Jupiter with the `@Transactional`
annotation from Spring, we could create an `@TransactionalIntegrationTest` annotation, as
follows:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	@Target(ElementType.METHOD)
	@Retention(RetentionPolicy.RUNTIME)
	@Transactional
	@Tag("integration-test") // org.junit.jupiter.api.Tag
	@Test // org.junit.jupiter.api.Test
	public @interface TransactionalIntegrationTest { }
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	@Target(AnnotationTarget.TYPE)
	@Retention(AnnotationRetention.RUNTIME)
	@Transactional
	@Tag("integration-test") // org.junit.jupiter.api.Tag
	@Test // org.junit.jupiter.api.Test
	annotation class TransactionalIntegrationTest { }
----
======

Then we can use our custom `@TransactionalIntegrationTest` annotation to simplify the
configuration of individual JUnit Jupiter based test methods, as follows:

[tabs]
======
Java::
+
[source,java,indent=0,subs="verbatim,quotes",role="primary"]
----
	@TransactionalIntegrationTest
	void saveOrder() { }

	@TransactionalIntegrationTest
	void deleteOrder() { }
----

Kotlin::
+
[source,kotlin,indent=0,subs="verbatim,quotes",role="secondary"]
----
	@TransactionalIntegrationTest
	fun saveOrder() { }

	@TransactionalIntegrationTest
	fun deleteOrder() { }
----
======
