Maven Surefire (JUnit) specific log4j configuration

To have a log4j configuration specific to your tests, for example if your normal log4 configuration write the logs in a file on server for a webapp, do the following:

1. create a file src/test/resources/test-log4j.properties containing the configuration of log4j for your tests e.g. :
   
   log4j.rootLogger=DEBUG, R
   log4j.appender.R=org.apache.log4j.ConsoleAppender
   log4j.appender.R.layout=org.apache.log4j.PatternLayout
   log4j.appender.R.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{3}:%L - %m%n
   
   
2. Edit your pom.xml like this:
   

   
   
   
    ...
    
   
      
        maven-surefire-plugin
        2.3
        
          
            
              
              log4j.configuration
              test-log4j.properties
            
          
        
      
      ...
    
   
   
   

   
   
3. Note: my normal log4j.properties is located in src/main/webapp/WEB-INF/classes/.
