Boundary Value Generator

Automate BVA and Equivalence Partitioning. Enter your range limits to generate all critical test data points instantly.

BVA Rules Used

Boundary Value Analysis (BVA) is based on the principle that most errors occur at the extreme boundaries of input ranges.

Minimum (Min)The exact lowest boundary. Expected to be Valid.
Just Below Min (Min-)Lowest boundary minus one. Expected to be Invalid.
Just Above Min (Min+)Lowest boundary plus one. Expected to be Valid.
NominalA value exactly in the middle of the range. Valid.

Why Use the Boundary Value Generator?

In Software Testing, manually calculating boundary values for every input field is tedious and prone to human error. Whether you are testing an "Age" field (18-60) or a "Quantity" field, our Boundary Value Generator ensures you never miss a critical edge case. This tool is a favorite among Manual Testers and QA Lead professionals for creating high-coverage test cases in seconds.

Equivalence Partitioning vs. BVA

While Equivalence Partitioning (EP) helps you divide input data into valid and invalid classes, BVA focuses on the points where those classes meet. Combining these two techniques provides the most robust test coverage. Use this tool alongside our JSONPath Evaluator and Assertion Generator to build a complete API and Functional testing suite.

Limitless and Secure Testing

At Software Testers Hub, we prioritize your data privacy. This tool runs entirely on client-side JavaScript; your input ranges and field names are never uploaded to our server. This makes it safe for enterprise use and allows us to offer unlimited usage to our community of 50,000+ testers. No more manual calculations—just enter your limits and start testing.

Pro Tip: After generating your boundary test cases, log your execution results in the Reporting Hub or audit your test scenarios for maximum coverage with the Scenario Audit Tool.
