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 once after all tests in the container have been executed.
AfterEachCallback	AfterEachCallback defines the API for Extensions that wish to provide additional behavior to tests after an individual test and any user-defined teardown methods (e.g., @AfterEach methods) for that test have been executed.
AfterTestExecutionCallback	AfterTestExecutionCallback defines the API for Extensions that wish to provide additional behavior to tests immediately after an individual test has been executed but before any user-defined teardown methods (e.g., @AfterEach methods) have been executed for that test.
BeforeAllCallback	BeforeAllCallback defines the API for Extensions that wish to provide additional behavior to test containers once before all tests in the container have been executed.
BeforeEachCallback	BeforeEachCallback defines the API for Extensions that wish to provide additional behavior to tests before an individual test and any user-defined setup methods (e.g., @BeforeEach methods) for that test have been executed.
BeforeTestExecutionCallback	BeforeTestExecutionCallback defines the API for Extensions that wish to provide additional behavior to tests immediately before an individual test is executed but after any user-defined setup methods (e.g., @BeforeEach methods) have been executed for that test.
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.
InvocationInterceptor	InvocationInterceptor defines the API for Extensions that wish to intercept calls to test code.
InvocationInterceptor.Invocation<T>	An invocation that returns a result and may throw a Throwable.
LifecycleMethodExecutionExceptionHandler	LifecycleMethodExecutionExceptionHandler defines the API for Extensions that wish to handle exceptions thrown during the execution of @BeforeAll, @BeforeEach, @AfterEach, and @AfterAll lifecycle methods.
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.
ReflectiveInvocationContext<T extends Executable>	ReflectiveInvocationContext encapsulates the context of a reflective invocation of an executable (method or constructor).
TestExecutionExceptionHandler	TestExecutionExceptionHandler defines the API for Extensions that wish to handle exceptions thrown during test execution.
TestInstanceFactory	TestInstanceFactory defines the API for Extensions that wish to create test instances.
TestInstanceFactoryContext	TestInstanceFactoryContext encapsulates the context in which a test class is to be instantiated by a TestInstanceFactory.
TestInstancePostProcessor	TestInstancePostProcessor defines the API for Extensions that wish to post-process test instances.
TestInstancePreDestroyCallback	TestInstancePreDestroyCallback defines the API for Extensions that wish to process test instances after they have been used in tests but before they are destroyed.
TestInstances	TestInstances encapsulates the test instances of a test.
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.
TestWatcher	TestWatcher defines the API for Extensions that wish to process test results.

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.
TestInstantiationException	Thrown if an error is encountered during the execution of a TestInstanceFactory.

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.
