SQL and Licensing

I have a live SQL 2014 database in production, hosted on a Windows 2012 Server.

I need to setup a test server with a copy of the SQL database. 

I am planning to setup a test server in my VMWare environment, install a fresh copy of SQL 2014, and perform a restore from a backup of the live database.

Do I need to worry about licensing for the test environment?

Thanks!
