Interface TestWatcher

  • All Superinterfaces:
    Extension
    @API(status=EXPERIMENTAL,
     since="5.4")
public interface TestWatcher
extends Extension
    TestWatcher defines the API for Extensions that wish to process test results.

    The methods in this API are called after a test has been skipped or executed. Any CloseableResource objects stored in the Store of the supplied ExtensionContext will have already been closed before methods in this API are invoked.

    Please note that this API is currently only used to report the results of @Test methods and @TestTemplate methods (e.g., @RepeatedTest and @ParameterizedTest). Moreover, if there is a failure at the class level — for example, an exception thrown by a @BeforeAll method — no test results will be reported.

    Extensions implementing this API can be registered at any level.

    Exception Handling

    In contrast to other Extension APIs, a TestWatcher is not permitted to adversely influence the execution of tests. Consequently, any exception thrown by a method in the TestWatcher API will be logged at WARNING level and will not be allowed to propagate or fail test execution.

    Since:
    5.4
