KARATE: print statement doesn't write to console with log4j2

Question

I have spring boot application and use karate for testing. I used log4j2 for logging. Karate use logback as a log library. I found this link for basic configuration of log4j2 with karate. But unfortunately print statement in the feature file is not written to console.

This is my Simple test to print to console.

Scenario: Print to Console
    * print 'Hello Word'

Log4j2.properties file

log4j.rootLogger = INFO, CONSOLE
log4j.appender.CONSOLE = org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayout

As you see bellow I excluded logback dependecies from karate with this code

testImplementation('com.intuit.karate:karate-junit5:0.9.6') {
        exclude module: "logback-classic"
    }
    testImplementation('com.intuit.karate:karate-apache:0.9.6') {
        exclude module: "logback-classic"
    }

    }

        return Karate.run().relativeTo(getClass());
    }

}

Karate Config

function fn() {

   var port = karate.properties['server.port'];
   if (!port) {
       port = 8080;
     }
    var config = {
        baseUrl : 'http://localhost:'+port,
        uuid: function(){ return java.util.UUID.randomUUID() + '' },
        isoDateTime: function(){ return java.time.OffsetDateTime.now().format(java.time.format.DateTimeFormatter.ISO_DATE_TIME)}
    };


    return config;
}

Answer 1

it start working after changing configuration of log4j2.properties files

New configuration as follows:

appenders = console
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout = org.apache.log4j.PatternLayout


rootLogger.level = debug
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT
