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	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	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	TestInstancePostProcessor	TestInstancePostProcessor defines the API for Extensions that wish to post-process 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	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.
