@ExtendWith is a repeatable annotation
that is used to register extensions for the annotated
test class, test interface, test method, parameter, or field.
Annotated parameters are supported in test class constructors, in test
methods, and in @BeforeAll, @AfterAll, @BeforeEach,
and @AfterEach lifecycle methods.
@ExtendWith fields may be either static or non-static.
@ExtendWith fields are inherited from superclasses as long as they
are not hidden or overridden. Furthermore, @ExtendWith
fields from superclasses will be registered before @ExtendWith fields
in subclasses.
When @ExtendWith is present on a test class, test interface, or
test method or on a parameter in a test method or lifecycle method, the
corresponding extensions will be registered in the order in which the
@ExtendWith annotations are discovered. For example, if a test class
is annotated with @ExtendWith(A.class) and then with
@ExtendWith(B.class), extension A will be registered before
extension B.
By default, if multiple extensions are registered on fields via
@ExtendWith, they will be ordered using an algorithm that is
deterministic but intentionally nonobvious. This ensures that subsequent runs
of a test suite execute extensions in the same order, thereby allowing for
repeatable builds. However, there are times when extensions need to be
registered in an explicit order. To achieve that, you can annotate
@ExtendWith fields with @Order.
Any @ExtendWith field not annotated with @Order will be
ordered using the default order
value. Note that @RegisterExtension fields can also be ordered with
@Order, relative to @ExtendWith fields and other
@RegisterExtension fields.
