There are several important factors to consider when you are planning to do prototyping for user testing. In this article from July 2002, Chris Farnum explains how to make the right choice about fidelity, level of interactivity and the medium for your test.
"In theory, low-fidelity sketches are also a time-saver, but this really depends on your point of view. Personally, I like to draw diagrams and wireframes in Visio where I can revise and move things around without erasing and redrawing."
"In the grand tradition of Goldilocks, I find myself drawn to the middle approach. A medium-fidelity approach tends to include some visual design and a level of detail somewhere between high and low fidelity."
"You can mix these three variables (fidelity, interactivity and medium) in many different combinations. The exact combination you choose should match the goals you determine for your testing."
