Package org.junit.jupiter.api.extension

JUnit Jupiter API for writing extensions.

Interface Summary

Interface	Description
AfterAllCallback	AfterAllCallback defines the API for Extensions that wish to provide additional behavior to test containers after all tests have been invoked.
AfterEachCallback	AfterEachCallback defines the API for Extensions that wish to provide additional behavior to tests after each test method has been invoked.
AfterTestExecutionCallback	AfterTestExecutionCallback defines the API for Extensions that wish to provide additional behavior to tests immediately after each test has been executed.
BeforeAllCallback	BeforeAllCallback defines the API for Extensions that wish to provide additional behavior to test containers before all tests are invoked.
BeforeEachCallback	BeforeEachCallback defines the API for Extensions that wish to provide additional behavior to tests before each test is invoked.
BeforeTestExecutionCallback	BeforeTestExecutionCallback defines the API for Extensions that wish to provide additional behavior to tests immediately before each test is executed.
ExecutionCondition	ExecutionCondition defines the Extension API for programmatic, conditional test execution.
Extension	Marker interface for all extensions.
ExtensionContext	ExtensionContext encapsulates the context in which the current test or container is being executed.
ExtensionContext.Store	Store provides methods for extensions to save and retrieve data.
ExtensionContext.Store.CloseableResource	Classes implementing this interface indicate that they want to ExtensionContext.Store.CloseableResource.close() some underlying resource or resources when the enclosing Store is closed.
ParameterContext	ParameterContext encapsulates the context in which an Executable will be invoked for a given Parameter.
ParameterResolver	ParameterResolver defines the API for Extensions that wish to dynamically resolve arguments for parameters at runtime.
TestExecutionExceptionHandler	TestExecutionExceptionHandler defines the API for Extensions that wish to handle exceptions thrown during test execution.
TestInstancePostProcessor	TestInstancePostProcessor defines the API for Extensions that wish to post-process test instances.
TestTemplateInvocationContext	TestTemplateInvocationContext represents the context of a single invocation of a test template.
TestTemplateInvocationContextProvider	TestTemplateInvocationContextProvider defines the API for Extensions that wish to provide one or multiple contexts for the invocation of a @TestTemplate method.

Class Summary

Class	Description
ConditionEvaluationResult	The result of evaluating an ExecutionCondition.
ExtensionContext.Namespace	A Namespace is used to provide a scope for data saved by extensions within a ExtensionContext.Store.

Exception Summary

Exception	Description
ExtensionConfigurationException	Thrown if an error is encountered regarding the configuration of an extension.
ExtensionContextException	Thrown if an error is encountered regarding the use of an ExtensionContext or ExtensionContext.Store.
ParameterResolutionException	Thrown if an error is encountered in the configuration or execution of a ParameterResolver.

Annotation Types Summary

Annotation Type	Description
ExtendWith	@ExtendWith is a repeatable annotation that is used to register extensions for the annotated test class or test method.
Extensions	@Extensions is a container for one or more @ExtendWith declarations.
RegisterExtension	@RegisterExtension is used to register an Extension via a field in a test class.
