 src/test/resourcesにいれておけばmaven packageの時には、packageに含まれない。

src/test/java/example01/HelloTest.java

package example01;

import junit.framework.*;

import org.apache.commons.logging.*;

public class LoggingTest extends TestCase
{
    private static final Log log = LogFactory.getLog(LoggingTest.class);

    public void testLogging()
    {
        log.trace("testLogging()");
    }
}
