Any Tutorial for using JUnit in IntelliJ IDEA

Hi,

Is there a tutorial to setup and use JUnit with IntelliJ IDEA 13.x? Like this one Using JUnit in Eclipse.
Found this blog article Running Unit Tests Inside IntelliJ IDEA  Is this all I need to run a JUnit test?

I would greatly appreciate if you can direct me to documentation or tutorials about recommended practices for Unit testing integration in IntelliJ IDEA. Thanks in advance for any help.
