Exception Handling

Exceptions thrown during the test execution may be intercepted and handled accordingly before propagating further, so that certain actions like error logging or resource releasing may be defined in specialized Extensions. JUnit Jupiter offers API for Extensions that wish to handle exceptions thrown during @Test methods via TestExecutionExceptionHandler and for those thrown during one of test lifecycle methods (@BeforeAll, @BeforeEach, @AfterEach and @AfterAll) via LifecycleMethodExecutionExceptionHandler.

The following example shows an extension which will swallow all instances of IOException but rethrow any other type of exception.
