Interface TestExecutionExceptionHandler

  • All Superinterfaces:
    Extension
    All Known Implementing Classes:
    ExpectedExceptionSupport
    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 TestExecutionExceptionHandler
    extends Extension
    TestExecutionExceptionHandler defines the API for Extensions that wish to handle exceptions thrown during test execution.

    In this context, test execution refers to the physical invocation of a @Test method and not to any test-level extensions or callbacks.

    Common use cases include swallowing an exception if it's anticipated or rolling back a transaction in certain error scenarios.

    Constructor Requirements

    Consult the documentation in Extension for details on constructor requirements.

      • handleTestExecutionException

        void handleTestExecutionException​(ExtensionContext context,
                                          Throwable throwable)
                                   throws Throwable
        Handle the supplied throwable.

        Implementors must perform one of the following.

        1. Swallow the supplied throwable, thereby preventing propagation.
        2. Rethrow the supplied throwable as is.
        3. Throw a new exception, potentially wrapping the supplied throwable.

        If the supplied throwable is swallowed, subsequent TestExecutionExceptionHandlers will not be invoked; otherwise, the next registered TestExecutionExceptionHandler (if there is one) will be invoked with any Throwable thrown by this handler.

        Note that the execution exception in the supplied ExtensionContext will not contain the Throwable thrown during invocation of the corresponding @Test method.

        Parameters:
        context - the current extension context; never null
        throwable - the Throwable to handle; never null
        Throws:
        Throwable
