Boundary-value test generator
Turn a signal range, resolution, and thresholds into a reusable set of boundary tests. Export the cases as CSV.
Your result
ON YOUR DEVICEEnter your inputs and calculate to see the result.
Test around the decision.
Generate minimum and maximum neighbours, a nominal value, and three values around each threshold. Duplicate values are combined. The table distinguishes range violations from values that do not lie on the configured resolution grid. These are candidate test inputs; add expected ECU behaviour from your requirements.
For each boundary b: b − resolution, b, b + resolution
Grid: minimum + k × resolution, where k is an integer
