/**
 * {@code @AfterEach} is used to signal that the annotated method should be
 * executed after each {@code @Test},
 * {@code @RepeatedTest}, {@code @ParameterizedTest}, {@code @TestFactory},
 * and {@code @TestTemplate} method in the current test class.
 *
 * 

Method Signatures

* *

{@code @AfterEach} methods must have a {@code void} return type, * must not be {@code private}, and must not be {@code static}. * They may optionally declare parameters to be resolved by * {@link org.junit.jupiter.api.extension.ParameterResolver ParameterResolvers}. * *

Inheritance and Execution Order

* *

{@code @AfterEach} methods are inherited from superclasses as long as * they are not overridden. Furthermore, {@code @AfterEach} methods from * superclasses will be executed after {@code @AfterEach} methods in subclasses. * *

Similarly, {@code @AfterEach} methods declared as interface default * methods are inherited as long as they are not overridden, and * {@code @AfterEach} default methods will be executed after {@code @AfterEach} * methods in the class that implements the interface. * *

JUnit Jupiter does not guarantee the execution order of multiple * {@code @AfterEach} methods that are declared within a single test class or * test interface. While it may at times appear that these methods are invoked * in alphabetical order, they are in fact sorted using an algorithm that is * deterministic but intentionally non-obvious. * *

In addition, {@code @AfterEach} methods are in no way linked to * {@code @BeforeEach} methods. Consequently, there are no guarantees with * regard to their wrapping behavior. For example, given two * {@code @BeforeEach} methods {@code createA()} and {@code createB()} as well * as two {@code @AfterEach} methods {@code destroyA()} and {@code destroyB()}, * the order in which the {@code @BeforeEach} methods are executed (e.g. * {@code createA()} before {@code createB()}) does not imply any order for the * seemingly corresponding {@code @AfterEach} methods. In other words, * {@code destroyA()} might be called before or after * {@code destroyB()}. The JUnit Team therefore recommends that developers * declare at most one {@code @BeforeEach} method and at most one * {@code @AfterEach} method per test class or test interface unless there are * no dependencies between the {@code @BeforeEach} methods or between the * {@code @AfterEach} methods. * *

Composition

* *

{@code @AfterEach} may be used as a meta-annotation in order to create * a custom composed annotation that inherits the semantics of * {@code @AfterEach}. * * @since 5.0 * @see BeforeEach * @see BeforeAll * @see AfterAll * @see Test * @see RepeatedTest * @see TestFactory * @see TestTemplate */ @Target({ ElementType.ANNOTATION_TYPE, ElementType.METHOD }) @Retention(RetentionPolicy.RUNTIME) @Documented @API(status = STABLE, since = "5.0") public @interface AfterEach { }
