Let's assume I gave the participant the task of finding the hardcover book "Owls of North America" by John P. Author. For simplicity's sake, the only navigation entries available are the following facets: Subject, Author, and Format. The participant could start on any of these paths, and at any point filter down on any of the other facets. Now, this situation leads me to think that I need to plan for at least 9 different possible interaction paths (3^3). This could really get out of hand in a non-trivial example, of course. So, I'm interested in seeing how this situation might be approached. Thinking more broadly, I would think that testing something like tag navigation might also incur the same challenge.
We've tested faceted navigation with paper prototypes by creating "slices" of pages for each facet. Also, in the testing, we knew the tasks (since we designed them), so were prepared for the likely facets the participant would choose.
You could do the same with an interactive prototype, but it would take a bit of coding effort. That's why we start with paper -- quick return on minimal investment with minimized risk.
