Domain Testing (Boundary Value Analysis)

What is Boundary Value Analysis?

Boundary value analysis focuses on values at and around the boundaries of input domains. Most defects occur at boundaries — this technique efficiently finds them.

How to use this tool?

1. Enter the minimum and maximum valid values for your input
2. The tool generates all boundary test cases automatically
3. Values include: below min, at min, min+1, max-1, at max, above max
4. Use these values in your test cases

Equivalence partitioning explained

The tool identifies equivalence partitions: valid range (values that should be accepted), invalid low range (below minimum), and invalid high range (above maximum). Test one value from each partition.
