  • java.lang.Object
    • org.apache.log4j.AppenderSkeleton

    public class NullAppender
    extends org.apache.log4j.AppenderSkeleton
    Log4J Log Appender, which does nothing. Logs simply goes into a black hole. This is primarily used to skip DEBUG and INFO logs being printed by testNg unit tests. We create multiple unit test(s) and suite(s) for each DEBUG and INFO log levels to get the proper coverage. Printing all the logs into the console clutters the console, makes the test execution slow and causes OOM. Null Appender helps to prevent the above problems.
