Here I am going to explain simple case study for BVA++, to easy understand we can take our Case Study itself, about the employees

Age: 24-54

Salary: 8000-20000

Employee Type :{ Tester, Developer, Manager}

Normally the Boundary value testing is used for single data validation with seven values like Min-1,Min,Min+1,Mid,Max-1,Max,Max+1, In this Boundary TestCase Generator we can generate multiple interactions of different fields range.

EG:

For Age the boundary values are 23,24,25,39,53,54,55

For Salary the boundary values are 7999, 8000,8001,14000,19999,20000,20001

For Employee the possibilities are Tester, Developer, Manager

TC1:

From the above example minValue of Age 24 can interact with maxValue of Salary 20000

If For single Data validation the minvalue of Age 24 will pass and there is a chance of occurring the bug when this minvalue is interacts with another Maxvalue or Max+1 value

TC2:

Max Value of Age 54+ Mid Value of Salary 14000+Manager

Like above TestCases we can write multiple interactions.

Have a nice Day
