What is the most common practice in performing EMC tests for PCB assemblies

Ok, I am a software guy and new to electronics.I am learning PCB design: http://green-electronic-tutorial.blogspot.com. My question:

What is the most common practice in performing EMC tests for PCB assemblies that will be sold without a housing? In my case it is an FPGA development board. Is it possible to design excessive switching hardware in a way that it passes CE and FCC testing without a metal housing? Or do you usually define a designated case of application with a housing?
