Test Analysis and Test Design

A new banking system has two customer types, two account types, and will operate in two different countries.

How many test cases are required when using the pairwise testing technique and an appropriate 2-wise orthogonal array?

Explanation

For three factors with two values each, a 2-wise orthogonal array uses four test cases. These four combinations provide coverage of every possible pair of values across customer type, account type, and country.
