title: Software Testing Technique for Radio Button of possible input combinations
body: <p>So I'm trying to figure out a Software Testing technique that would decrease the amount of test combinations inputs of a Radio Button dialog. The dialog has three sets of radio buttons. The scenario is for an application on a Flight.</p>
  <p>1st Set - {England, Scotland, Wales, Northern Ireland}</p>
  <p>2nd Set - {Aisle, Window Seat}</p>
  <p>3rd Set - {Coach, Business, Economy}</p>
  <p>Using Cartesian Method the total number of tests for possible combinations inputs is 4X2X3 = 24 Tests</p>
  <p>I want to reduce this number of combinations with a valid functional testing technique. So my question is what type of testing will this be?</p>
  <p>Suggestions will be very helpful. Thanks</p>
