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
