How to print logs on console in Intellij?

Question

Can't get logs to show up on console while running unit tests. Instead, I see this message every time I run a unit test -

log4j:WARN No appenders could be found for logger. 
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

log4j.properties contains this -

log4j.rootLogger=info, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender

I'm pretty sure that this needs to be configured in run configurations but just can't get it to work. Would really appreciate any help on this. Thanks!

It's inside the project folder. Have marked that as a resource folder. — mindreader, Jul 15 '15 at 09:06
Is *.properties included in Settings | Build, Execution, Deployment | Compiler | Resource patterns? — yole, Jul 15 '15 at 09:10
Did you define the `stdout` appender in `log4j.properties` too? — maba, Jul 15 '15 at 09:30
@yole - Thanks for pointing that out, it wasn't. Have added it now. But it's not working. — mindreader, Jul 15 '15 at 22:31
@maba - have this in the properties file log4j.appender.stdout=org.apache.log4j.ConsoleAppender — mindreader, Jul 15 '15 at 22:32

Finally got it to work! Added this to VM options -

-Dlog4j.configuration=file:{path-to-properties-file}/log4j.properties

as explained here by 30thh.

I had it added in my default unit test configuration, but it wasn't being picked up by current configuration.
