Boundary Value Calculator
Calculate exact boundary values for test cases from any numeric range. Essential for QA boundary testing.
Examples of use
- Calculate boundary values for an age field with range 18-65
- Generate edge cases for a numeric input with min 0 and max 100
- Find exact boundary values for a quantity field ranging from 1-50
When to use this tool?
- When writing test cases for numeric input fields with defined ranges
- When performing equivalence partitioning and boundary analysis
- When validating min/max constraints in forms or APIs
Frequently asked questions
- What is Boundary Value Analysis?
- Boundary Value Analysis (BVA) is a testing technique where test cases are designed to include values at the boundaries of input domains. It is based on the observation that errors tend to occur near the extreme values of input ranges.
- Why test at boundaries?
- Most defects in software occur at the edges of input ranges rather than in the middle. Testing boundary values (Min-1, Min, Min+1, Max-1, Max, Max+1) catches off-by-one errors and range validation bugs.
