Modify logging level on Selenium Firefox driver?

Question

I'm running tests for a Java/Maven project using Selenium 3.4 and the FirefoxDriver (not the Marionette/Geckodriver). I have Firefox 45.9.0 installed. Our test code uses Log4j2 and I can set the logging level to whatever I like, but no matter what I set it to I get log messages like this in the console:

1501873908911   addons.manager  DEBUG   Application has been upgraded

It looks like something inside the FirefoxDriver, or inside Firefox itself, is logging at a DEBUG level no matter what I set our logging level to.

I looked at this question but I can't figure out how to translate the Python answer to our Java code:

Example Python:

import logging
from selenium.webdriver.remote.remote_connection import LOGGER
LOGGER.setLevel(logging.WARNING)

Our Java code:

DesiredCapabilities capability = DesiredCapabilities.firefox();
FirefoxProfile profile=new FirefoxProfile();
capability.setCapability(FirefoxDriver.PROFILE, profile);
mDriver = new FirefoxDriver(capability);

I've tried several permutations but nothing seems to affect this logging - these messages appear in the console no matter what. Anyone have any way to control this logging?

Answer 1

These log are from selenium library, if you don't want to see it => turn it off by declare the scope of logging to only in your package or simply turn it off.

For example you just want to get log message from your code, the root package of your code is: com.example.mycode then open the log4j config file and add this: log4j.logger.com.example.mycode = DEBUG|INFO.

Or you can turn off only the logging from selenium: java.util.logging.Logger.getLogger("org.openqa.selenium").setLevel(Level.OFF);
