Boundary value testing or Equivalence Partition Testing

It is used to check range-based data using minium,minium-1, minimum+1, max,max-1 and max+1, and middle value.

for example, if we check the marriage portal then we check the minimum age limit for males and females.

max-age limit and we can check the average age limit in the portal.


Equivalence Partition means we will subdivide the range data if the data range is too large. It is part of boundary value testing.

for example, if we want to check the income limit from  1000 rs to 1 crore then we can create a sub-partition according to the income tax slab.
