beforeEach

public void beforeEach(ExtensionContext context)

Description copied from interface: BeforeEachCallback

Callback that is invoked before each test is invoked.

Specified by:

beforeEach in interface BeforeEachCallback

Parameters:

context - the current extension context; never null

handleTestExecutionException

public void handleTestExecutionException(ExtensionContext context,
                                         java.lang.Throwable throwable)
                                  throws java.lang.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:

java.lang.Throwable

afterEach

public void afterEach(ExtensionContext context)

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

invokeAppropriateMethodOnRuleAnnotatedMembers

private long invokeAppropriateMethodOnRuleAnnotatedMembers(ExtensionContext context,
                                                           java.util.function.Consumer<java.util.List<TestRuleAnnotatedMember>> ordering,
                                                           java.util.function.Consumer<GenericBeforeAndAfterAdvice> methodCaller)

Returns:

the number of appropriate rule-annotated members that were discovered
