2.2. Test Classes and Methods

Test Class: any top-level class, static member class, or @Nested class that contains at least one test method.

Test classes must not be abstract and must have a single constructor.

Test Method: any instance method that is directly annotated or meta-annotated with @Test, @RepeatedTest, @ParameterizedTest, @TestFactory, or @TestTemplate.

Lifecycle Method: any method that is directly annotated or meta-annotated with @BeforeAll, @AfterAll, @BeforeEach, or @AfterEach.

Test methods and lifecycle methods may be declared locally within the current test class, inherited from superclasses, or inherited from interfaces (see Test Interfaces and Default Methods). In addition, test methods and lifecycle methods must not be abstract and must not return a value.

The following test class demonstrates the use of @Test methods and all supported lifecycle methods. For further information on runtime semantics, see Test Execution Order and Wrapping Behavior of Callbacks.
