JUnit5 Jupiter (6)  Implementing many Interfaces with respective Test

The TimeExecutionLogger Interface is extended by the class TimingExtencion with @ExtendsWith,

Observe that InterfaceLoggedTest and TimingExtension has a logger, by this way we generate two loggers with log4j2.

@Tag("timed")
@ExtendWith(TimingExtension.class)
public interface TimeExecutionLogger {
}

public interface InterfaceDynamicTest {
    @TestFactory    default Stream<DynamicTest> dynamicTestForPalindromes() {
        return Stream.of("asdfa","asdfas","adsf","asdf")
                .map( text -> dynamicTest( text, () -> assertTrue(isPalindrome(text))));    }

    default boolean isPalindrome(String text) {
        return true;    }; //just dummy}

@TestInstance(TestInstance.Lifecycle.PER_CLASS)
public interface InterfaceLoggedTest {
    static Logger logger = LogManager.getLogger(InterfaceLoggedTest.class.getName());
    @BeforeAll    default void beforeAllTest() {
        logger.info("Antes que todas las pruebas");    }

    @AfterAll    default void afterAllTest() {
        logger.info("Despues de todas las pruebas");    }

    @BeforeEach    default void beforeEachTest( TestInfo testInfo){
        logger.info( () -> String.format("antes   de %s", testInfo.getDisplayName()));    }

    @AfterEach    default void afterEachTest( TestInfo testInfo) {
        logger.info( ()-> String.format("despues de %s", testInfo.getDisplayName()));    }

    void thisMethodIsLoggedByInterface();    void alsoLoggedByInterface();
}

public class ImplemManyTimeInterfaceTest implements TimeExecutionLogger,

                               InterfaceLoggedTest, InterfaceDynamicTest {
    @Test    void isEqualValue() {
        assertEquals( 1, "a".length(), "siempre es Equals");    }

    @Override    public void thisMethodIsLoggedByInterface() {

    }

    @Override    public void alsoLoggedByInterface() {

    }
}

Log files generated with the test

20:55:58.106| INFO  | TimingExtension | metodo [isEqualValue] tiempo 2 ms.

   With JUnit5 Architecture can be achieved interesting and versatile test implementations.
