Class ExpectedExceptionSupport

java.lang.Object

org.junit.jupiter.migrationsupport.rules.ExpectedExceptionSupport

All Implemented Interfaces:

AfterEachCallback, Extension, TestExecutionExceptionHandler

@API(status=EXPERIMENTAL,
     since="5.0")
public class ExpectedExceptionSupport
extends Object
implements AfterEachCallback, TestExecutionExceptionHandler

This Extension provides native support for the ExpectedException 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.

Since:

5.0

Method Detail

handleTestExecutionException

public void handleTestExecutionException(ExtensionContext context,
                                         Throwable throwable)
                                  throws Throwable

Description copied from interface: TestExecutionExceptionHandler

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.

Specified by:

handleTestExecutionException in interface TestExecutionExceptionHandler

Parameters:

context - the current extension context; never null

throwable - the Throwable to handle; never null

Throws:

Throwable

afterEach

public void afterEach(ExtensionContext context)
               throws Exception

Description copied from interface: AfterEachCallback

Callback that is invoked after each test has been invoked.

Specified by:

afterEach in interface AfterEachCallback

Parameters:

context - the current extension context; never null

Throws:

Exception
