No. The goal is to test your testing methodology, general knowledge and creativity. You have to be able to both structure your answer ("First, I'd do a quick smoke test to see if nothing fails catastrophically; second, I'd check this an this to see if specs have been respected; now that we established it works fine under normal circumstances, let's test edge cases etc. As a bonus, we can finally run some usability/ergonomy tests...") and be able to think of creative cases on the spot ("how does it fare if you plug it into an outlet with a different voltage?"). Basically, they want to know how you think when you approach a testing problem. Taking it like a dumb question ("er.... turn it on and see if it works") is probably the worst answer you can give.
