@FunctionalInterface @API(status=STABLE, since="5.0") public interface BeforeEachCallback extends Extension
BeforeEachCallbackdefines the API for
Extensionsthat wish to provide additional behavior to tests before an individual test and any user-defined setup methods (e.g.,
@BeforeEachmethods) for that test have been executed.
Concrete implementations often implement
AfterEachCallbackas well. If you do not wish to have your callbacks wrapped around user-defined setup and teardown methods, implement
Consult the documentation in
Extensionfor details on constructor requirements.
JUnit Jupiter guarantees wrapping behavior for multiple registered extensions that implement lifecycle callbacks such as
That means that, given two extensions
Extension2, any "before" callbacks implemented by
Extension1are guaranteed to execute before any "before" callbacks implemented by
Extension2. Similarly, given the two same two extensions registered in the same order, any "after" callbacks implemented by
Extension1are guaranteed to execute after any "after" callbacks implemented by
Extension1is therefore said to wrap
