----------------------------------

             Summary: Update unit tests to use Log4jConfig rule.
                 Key: LOG4J2-498
                 URL: https://issues.apache.org/jira/browse/LOG4J2-498
             Project: Log4j 2
          Issue Type: Sub-task
          Components: Core
    Affects Versions: 2.0-rc1
            Reporter: Matt Sicker


Every test that duplicates the following code (or some variant):

{code:java}
System.setProperty(ConfigurationFactory.CONFIGURATION_FILE_PROPERTY, "config-file.xml");
{code}

Along with retrieving the updated LoggerContext, resetting StatusLogger, etc., can all be cleaned up by using the Log4jConfig rule. There is one catch, however, that I've noticed in several tests. Where a log file is created and deleted for a test, many tests call {{file.delete()}} at the beginning of the test. This is done because the logger context is retrieved after the call, but the rule sets up the logger context before the test is executed. Thus, these calls should be eliminated while leaving the {{file.delete()}} at the end of the test method.
