Black Box – BVT on 2 Variables software testing

Suppose we have two variables x1 and x2 to test.

The range of x1: 10 to 90.

The range of x2: 20 to 70.

   X1 X2
Min1020
Min+1121
Nominal5045
Max-8969
Max9070

Test cases.

Total Test cases =

(Number of variables * Number of testing points without nominal ) + (1 for  Nominal)

                        9=2*4+1

There are total 2 variables x1 and x2.

There are 4 possible values like min, min+, max- and max.

1 is for nominal.

We can generate 9 test cases from both variables x1 and x2
