Hi Paul, You have different scenarios, or you have different designs? I'm not sure how you would test for validity of a scenario with usability testing -- in that case it sounds like you'd want to do contextual work to see if you find your scenarios 'in the wild.' But if what you really mean is that you have three slightly different designs, then you're right, you shouldn't test all three designs with the same individual. What this means, of course, is tripling the number of tests you need to do. For that reason, I probably wouldn't take the time to test all three. I'd test the most promising one and see how it does, and based on that test the others if there are problems with the first. If I had three slightly different designs and I wasn't sure what direction to go, I'd test them as paper prototypes rather than fully-implemented designs.
Some of the other responses seem to be confusing "showing people the design" with "usability testing." Showing non-designers a design will not likely get you good information; but running usability tests where they actually need to use the design will.

Does any have any suggestions for how to best design a test for a registration process. We have 3 different scenarios involving a step process. If we take a group of people and perform a usability test, should we put them through all three scenarios? We're thinking this might skew results as they'll become familiar with the scenario (because each scenario has relatively minor nuances for differences). Also, they could become fatigued. Any suggestions how to produce the best results and most accurate findings?
