JUnit Flashcards
@Test
Denotes that a method is a test method. Unlike JUnit 4’s @Test annotation, this annotation does not declare any attributes, since test extensions in JUnit Jupiter operate based on their own dedicated annotations. Such methods are inherited unless they are overridden.

@TestFactory
@TestTemplate
Denotes that a method is a template for test cases designed to be invoked multiple times depending on the number of invocation contexts returned by the registered providers. Such methods are inherited unless they are overridden.

@TestClassOrder
@TestMethodOrder
Used to configure the test method execution order for the annotated test class; similar to JUnit 4’s @FixMethodOrder. Such annotations are inherited.

@TestInstance
@DisplayName
Declares a custom display name for the test class or test method. Such annotations are not inherited.

@DisplayName
@DisplayNameGeneration
Declares a custom display name generator for the test class. Such annotations are inherited.

@DisplayNameGeneration
@BeforeEach
Denotes that the annotated method should be executed before each @Test, @RepeatedTest, @ParameterizedTest, or @TestFactory method in the current class; analogous to JUnit 4’s @Before. Such methods are inherited unless they are overridden.
Denotes that the annotated method should be executed before each @Test, @RepeatedTest, @ParameterizedTest, or @TestFactory method in the current class; analogous to JUnit 4’s @Before. Such methods are inherited unless they are overridden.
@BeforeEach
@AfterEach
Denotes that the annotated method should be executed after each @Test, @RepeatedTest, @ParameterizedTest, or @TestFactory method in the current class; analogous to JUnit 4’s @After. Such methods are inherited unless they are overridden.
Denotes that the annotated method should be executed after each @Test, @RepeatedTest, @ParameterizedTest, or @TestFactory method in the current class; analogous to JUnit 4’s @After. Such methods are inherited unless they are overridden.
@AfterEach
@BeforeAll
Denotes that the annotated method should be executed before all @Test, @RepeatedTest, @ParameterizedTest, and @TestFactory methods in the current class; analogous to JUnit 4’s @BeforeClass. Such methods are inherited unless they are overridden and must be static unless the “per-class” test instance lifecycle is used.
Denotes that the annotated method should be executed before all @Test, @RepeatedTest, @ParameterizedTest, and @TestFactory methods in the current class; analogous to JUnit 4’s @BeforeClass. Such methods are inherited unless they are overridden and must be static unless the “per-class” test instance lifecycle is used.
@BeforeAll
@AfterAll
Denotes that the annotated method should be executed after all @Test, @RepeatedTest, @ParameterizedTest, and @TestFactory methods in the current class; analogous to JUnit 4’s @AfterClass. Such methods are inherited unless they are overridden and must be static unless the “per-class” test instance lifecycle is used.
Denotes that the annotated method should be executed after all @Test, @RepeatedTest, @ParameterizedTest, and @TestFactory methods in the current class; analogous to JUnit 4’s @AfterClass. Such methods are inherited unless they are overridden and must be static unless the “per-class” test instance lifecycle is used.
@AfterAll
@Nested
Denotes that the annotated class is a non-static nested test class. On Java 8 through Java 15, @BeforeAll and @AfterAll methods cannot be used directly in a @Nested test class unless the “per-class” test instance lifecycle is used. Beginning with Java 16, @BeforeAll and @AfterAll methods can be declared as static in a @Nested test class with either test instance lifecycle mode. Such annotations are not inherited.

@Tag
Used to declare tags for filtering tests, either at the class or method level; analogous to test groups in TestNG or Categories in JUnit 4. Such annotations are inherited at the class level but not at the method level.
