How to include Log4j2 messages in TestNG reporting

Question

I would like to have the Log4j2 logging information available in the TestNG reports for all of the test cases.

TestNG uses a special logger class called Reporter.java t

From what I can tell you just need to implement a simple Appender. Something like:

@Plugin(name="Reporter", category ="Core", elementType="appender", printObject=true)
public class ReporterAppender extends AbstractAppender {

    private ReporterAppender(final String name, final Layout layout) {
        super(name, null, layout, false);
    }

    @Override
    public void append(final LogEvent event) {
        final Layout<? extends Serializable> layout = getLayout();
        if (layout != null && layout instanceof AbstractStringLayout) {
             Reporter.log(((AbstractStringLayout) layout).toSerializable(event));
        } else {
             Reporter.log(event.getMessage().getFormattedMessage();            }

    @PluginFactory
    public static ReporterAppender createAppender(
        @PluginAttribute("name") @Required(message = "A name for the Appender must be specified") final String name,
        @PluginElement("Layout") Layout<? extends Serializable> layout) {
        return new ReporterAppender(name, layout);
    }
}

Answer 2

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

add this in pom.xml

<dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.16</version>
        <scope>compile</scope>
    </dependency>

then you can use log.info or log.error etc...
