You mean "How to Test for Aerodynamics." There are two ways to do it, and both are very expensive. The first is to put the vehicle in a wind tunnel (as Freightliner, Navistar and Volvo have done). The second is to use "Computational Fluid Dynamics"- which means during the design phase, to put the design into a high-powered mobile workstation (such as the Lenovo(R) ThinkPad(R) W530 or W701 DS (the DS stands for Dual Screen)) and then send the design from the workstation to a supercomputer with a special program which checks and validates the design using computer modeling. Supercomputer time is very expensive (upwards of $1000/hour) as is wind tunnel time.
 
Both will achieve a similar result, but using the wind tunnel is far more reliable and takes less time, and is often used to validate the results of a test that is initially performed using Computational Fluid Dynamics.
 
Then there's Luigi Colani... the professor of fluid motion himself.
