Hi Team,

 

How to cover Logger.info(....), Logger.debug() etc using JUNIT5. I tried to search online but could not get a sample example.

 

 

 

and in our Main Class, we have below line for Logger object:

private static final Logger LOGGER= LoggerFactory.getLogger(MyMainClass.class);

 

An example reference will be appreciated.

 

Thank you.

Below is the example snippet how to use logger with info similarly u can use for other levels too debug/error.

import org.slf4j.Logger; import org.slf4j.LoggerFactory; @Model(adaptables = SlingHttpServletRequest.class) public class GetUrl { private static final Logger LOG = LoggerFactory.getLogger(GetUrl.class); @RequestAttribute @1497330(values = StringUtils.EMPTY) @14766979 private String linkUrl; @PostConstruct private void init() { LOG.info("Inside init method"); } }

    Hi @arvindpandey , 

    You may try /get help from default sample code provided by Adobe.

     

    private TestLogger logger = TestLoggerFactory.getTestLogger(fixture.getClass());

     


    @ExtendWith(AemContextExtension.class)
    class SimpleScheduledTaskTest {

        private SimpleScheduledTask fixture = new SimpleScheduledTask();

        private TestLogger logger = TestLoggerFactory.getTestLogger(fixture.getClass());

        @BeforeEach
        void setup() {
            TestLoggerFactory.clear();
        }

        @Test
        void run() {
            SimpleScheduledTask.Config config = mock(SimpleScheduledTask.Config.class);
            when(config.myParameter()).thenReturn("parameter value");

            fixture.activate(config);
            fixture.run();

            List<LoggingEvent> events = logger.getLoggingEvents();
            assertEquals(1, events.size());
            LoggingEvent event = events.get(0);
            assertEquals(Level.DEBUG, event.getLevel());
            assertEquals(1, event.getArguments().size());
            assertEquals("parameter value", event.getArguments().get(0));
        }
    }

      Hi,

      You may try static mocking as well but for this need to enable mock-maker-inline

       

      Logger mockedLogger = Mockito.mock(Logger.class);

        Were you able to resolve it ? I managed to create a test logger and it just resolved it
