@API(status=EXPERIMENTAL, since="5.0") public class ExpectedExceptionSupport extends Object implements AfterEachCallback, TestExecutionExceptionHandler
ThisExtension
provides native support for theExpectedException
rule from JUnit 4.By using this class-level extension on a test class,
ExpectedException
can continue to be used.However, you should rather switch to
Assertions.assertThrows(java.lang.Class<T>, org.junit.jupiter.api.function.Executable)
for new code.

handleTestExecutionException
public void handleTestExecutionException(ExtensionContext context, Throwable throwable) throws Throwable
Description copied from interface:TestExecutionExceptionHandler
Handle the suppliedthrowable
.Implementors must perform one of the following.
- Swallow the supplied
throwable
, thereby preventing propagation. - Rethrow the supplied
throwable
as is. - Throw a new exception, potentially wrapping the supplied
throwable
.
If the supplied
throwable
is swallowed, subsequentTestExecutionExceptionHandlers
will not be invoked; otherwise, the next registeredTestExecutionExceptionHandler
(if there is one) will be invoked with anyThrowable
thrown by this handler.Note that the
execution exception
in the suppliedExtensionContext
will not contain theThrowable
thrown during invocation of the corresponding@Test
method.- Specified by:
handleTestExecutionException
in interfaceTestExecutionExceptionHandler
- Parameters:
context
- the current extension context; nevernull
throwable
- theThrowable
to handle; nevernull
- Throws:
Throwable
- Swallow the supplied
