Software Testing Technique for Radio Button of possible input combinations

Question

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.

1st Set - {England, Scotland, Wales, Northern Ireland}

2nd Set - {Aisle, Window Seat}

3rd Set - {Coach, Business, Economy}

Using Cartesian Method the total number of tests for possible combinations inputs is 4X2X3 = 24 Tests

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?

Suggestions will be very helpful. Thanks

Answer 1

I did some reading and I managed to find the most suitable functional testing technique for this is Pairwise combinatorial testing.

This testing is the most suitable technique for combinations as it drastically decreases the number of test case count therefore, uses a much smaller test suite. Apart from decreasing test count, it cannot compromise on the test coverage. The test suite can cover all combinations; therefore, it is not exhaustive yet very effective in finding bugs.
