Wait, are you sure it's not just 4? Seems too simple.

So that's 2 x 2 x 2 = 8 test cases!

There are 2 customer types and 2 account types, right?

If I recall correctly, with 2 customer types, 2 account types, and 2 countries, we might end up with 8 combinations in total.

I’m a bit confused about the pairwise testing technique. Does it mean we only need to test combinations of one from each category?

I remember practicing a similar question where we had to calculate combinations. I think it might be 4 test cases?

I think we need to consider all combinations of customer types and account types, but I'm not sure how the countries factor in.
