If you are testing a simple design, should you be concerned if all results come back successful? The tested page has only three CTAs. To rule out the possibility that the participant only clicked on the available button, the test focused more on whether the user could explain why they clicked on this CTA and not the other two. The purpose was to see if the design and information was clear and what they expected to see next after they clicked on the CTA.
All participants showed a high level of understanding of the questions asked and were confident that they had all taken the correct action (which they all did correctly). Since this is such a simple design, should I expect a clear success rate, or because all participants did so well, is this a warning sign that something might be missing from the testing, or should I accept that the simple design met the requirements?
