Package org.junit.jupiter.api

JUnit Jupiter API for writing tests.

Interface Summary

Interface	Description
DisplayNameGenerator	DisplayNameGenerator defines the SPI for generating display names programmatically.
MethodDescriptor	MethodDescriptor encapsulates functionality for a given Method.
MethodOrderer	MethodOrderer defines the API for ordering the test methods in a given test class.
MethodOrdererContext	MethodOrdererContext encapsulates the context in which a MethodOrderer will be invoked.
RepetitionInfo	RepetitionInfo is used to inject information about the current repetition of a repeated test into @RepeatedTest, @BeforeEach, and @AfterEach methods.
TestInfo	TestInfo is used to inject information about the current test or container into to @Test, @RepeatedTest, @ParameterizedTest, @TestFactory, @BeforeEach, @AfterEach, @BeforeAll, and @AfterAll methods.
TestReporter	Parameters of type TestReporter can be injected into @BeforeEach and @AfterEach lifecycle methods as well as methods annotated with @Test, @RepeatedTest, @ParameterizedTest, @TestFactory, etc.

Class Summary

Class	Description
Assertions	Assertions is a collection of utility methods that support asserting conditions in tests.
Assumptions	Assumptions is a collection of utility methods that support conditional test execution based on assumptions.
DisplayNameGenerator.ReplaceUnderscores	Replace all underscore characters with spaces.
DisplayNameGenerator.Standard	Standard display name generator.
DynamicContainer	A DynamicContainer is a container generated at runtime.
DynamicNode	DynamicNode serves as the abstract base class for a container or a test case generated at runtime.
DynamicTest	A DynamicTest is a test case generated at runtime.
MethodOrderer.Alphanumeric	MethodOrderer that sorts methods alphanumerically based on their names using String.compareTo(String).
MethodOrderer.OrderAnnotation	MethodOrderer that sorts methods based on the @Order annotation.
MethodOrderer.Random	MethodOrderer that orders methods pseudo-randomly and allows for concurrent execution by default.

Enum Summary

Enum	Description
TestInstance.Lifecycle	Enumeration of test instance lifecycle modes.

Annotation Types Summary

Annotation Type	Description
AfterAll	@AfterAll is used to signal that the annotated method should be executed after all tests in the current test class.
AfterEach	@AfterEach is used to signal that the annotated method should be executed after each @Test, @RepeatedTest, @ParameterizedTest, @TestFactory, and @TestTemplate method in the current test class.
BeforeAll	@BeforeAll is used to signal that the annotated method should be executed before all tests in the current test class.
BeforeEach	@BeforeEach is used to signal that the annotated method should be executed before each @Test, @RepeatedTest, @ParameterizedTest, @TestFactory, and @TestTemplate method in the current test class.
Disabled	@Disabled is used to signal that the annotated test class or test method is currently disabled and should not be executed.
DisplayName	@DisplayName is used to declare a custom display name for the annotated test class or test method.
DisplayNameGeneration	@DisplayNameGeneration is used to declare a custom display name generator for the annotated test class.
Nested	@Nested is used to signal that the annotated class is a nested, non-static test class (i.e., an inner class) that can share setup and state with an instance of its enclosing class.
Order	@Order is an annotation that is used to configure the order in which the annotated element (i.e., field or method) should be evaluated or executed relative to other elements of the same category.
RepeatedTest	@RepeatedTest is used to signal that the annotated method is a test template method that should be repeated a specified number of times with a configurable display name.
Tag	@Tag is a repeatable annotation that is used to declare a tag for the annotated test class or test method.
Tags	@Tags is a container for one or more @Tag declarations.
Test	@Test is used to signal that the annotated method is a test method.
TestFactory	@TestFactory is used to signal that the annotated method is a test factory method.
TestInstance	@TestInstance is a type-level annotation that is used to configure the lifecycle of test instances for the annotated test class or test interface.
TestMethodOrder	@TestMethodOrder is a type-level annotation that is used to configure a MethodOrderer for the test methods of the annotated test class or test interface.
TestTemplate	@TestTemplate is used to signal that the annotated method is a test template method.
