Boundary Value Analysis:
Many systems have tendency to fail on boundary. So testing
boundary values of application is important. Boundary Value
Analysis (BVA) is a test Functional Testing technique where
the extreme boundary values are chosen. Boundary values
include maximum, minimum, just inside/outside boundaries,
typical values, and error values.
Extends equivalence partitioning
Test both sides of each boundary
Look at output boundaries for test cases too
Test min, min-1, max, max+1, typical values
BVA techniques:
1. Number of variables
For n variables: BVA yields 4n + 1 test case.
2. Kinds of ranges
Generalizing ranges depends on the nature or type of variables
Advantages of Boundary Value Analysis
1. Robustness Testing – Boundary Value Analysis plus values
that go beyond the limits
2. Min – 1, Min, Min +1, Nom, Max -1, Max, Max +1
3. Forces attention to exception handling
