Interface BeforeTestExecutionCallback
-
- All Superinterfaces:
Extension
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface @API(status=STABLE, since="5.0") public interface BeforeTestExecutionCallback extends Extension
BeforeTestExecutionCallback
defines the API forExtensions
that wish to provide additional behavior to tests immediately before each test is executed.Such callbacks will be invoked after any user defined setup methods (e.g.,
@BeforeEach
methods).Concrete implementations often implement
AfterTestExecutionCallback
as well.Constructor Requirements
Consult the documentation in
Extension
for details on constructor requirements.Wrapping Behavior
JUnit Jupiter guarantees wrapping behavior for multiple registered extensions that implement lifecycle callbacks such as
BeforeAllCallback
,AfterAllCallback
,BeforeEachCallback
,AfterEachCallback
,BeforeTestExecutionCallback
, andAfterTestExecutionCallback
.That means that, given two extensions
Extension1
andExtension2
withExtension1
registered beforeExtension2
, any "before" callbacks implemented byExtension1
are guaranteed to execute before any "before" callbacks implemented byExtension2
. Similarly, given the two same two extensions registered in the same order, any "after" callbacks implemented byExtension1
are guaranteed to execute after any "after" callbacks implemented byExtension2
.Extension1
is therefore said to wrapExtension2
