Uses of Extension in org.junit.jupiter.api.extension

Subinterfaces of Extension in org.junit.jupiter.api.extension

Modifier and Type	Interface	Description
interface	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.
interface	AfterClassTemplateInvocationCallback	AfterClassTemplateInvocationCallback defines the API for Extensions that wish to provide additional behavior once before each invocation of a @ClassTemplate.
interface	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.
interface	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.
interface	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.
interface	BeforeClassTemplateInvocationCallback	BeforeClassTemplateInvocationCallback defines the API for Extensions that wish to provide additional behavior once before each invocation of a @ClassTemplate.
interface	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.
interface	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.
interface	ClassTemplateInvocationContextProvider	ClassTemplateInvocationContextProvider defines the API for Extensions that wish to provide one or multiple contexts for the invocation of a @ClassTemplate.
interface	ExecutionCondition	ExecutionCondition defines the Extension API for programmatic, conditional test execution.
interface	InvocationInterceptor	InvocationInterceptor defines the API for Extensions that wish to intercept calls to test code.
interface	LifecycleMethodExecutionExceptionHandler	LifecycleMethodExecutionExceptionHandler defines the API for Extensions that wish to handle exceptions thrown during the execution of @BeforeAll, @BeforeEach, @AfterEach, and @AfterAll lifecycle methods.
interface	ParameterResolver	ParameterResolver defines the API for Extensions that wish to dynamically resolve arguments for parameters at runtime.
interface	PreInterruptCallback	PreInterruptCallback defines the API for Extensions that wish to be called prior to invocations of Thread.interrupt() by the Timeout extension.
interface	TestExecutionExceptionHandler	TestExecutionExceptionHandler defines the API for Extensions that wish to handle exceptions thrown during test execution.
interface	TestInstanceFactory	TestInstanceFactory defines the API for Extensions that wish to create test instances.
interface	TestInstancePostProcessor	TestInstancePostProcessor defines the API for Extensions that wish to post-process test instances.
interface	TestInstancePreConstructCallback	TestInstancePreConstructCallback defines the API for Extensions that wish to be invoked prior to creation of test instances.
interface	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.
interface	TestInstantiationAwareExtension	TestInstantiationAwareExtension defines the API for Extensions that are aware of or influence the instantiation of test classes.
interface	TestTemplateInvocationContextProvider	TestTemplateInvocationContextProvider defines the API for Extensions that wish to provide one or multiple contexts for the invocation of a @TestTemplate method.
interface	TestWatcher	TestWatcher defines the API for Extensions that wish to process test results.
