BeforeAllCallbackdefines the API for
Extensionsthat wish to provide additional behavior to test containers once before all tests in the container have been executed.
Concrete implementations often implement
AfterAllCallback as well.
Extensions that implement
BeforeAllCallback must be registered at
the class level.
Consult the documentation in
Extension for details on
JUnit Jupiter guarantees wrapping behavior for multiple
registered extensions that implement lifecycle callbacks such as
That means that, given two extensions
Extension1 registered before
Extension2, any "before" callbacks implemented by
are 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
are guaranteed to execute after any "after" callbacks implemented by
Extension1 is therefore said to wrap
beforeAllCallback that is invoked once before all tests in the current container.
