Check an AI-built form with missing and awkward inputs

Fictional local form rules. This example runs locally; files selected here stay in browser memory.

Test the actual input boundary

Give independent expected cases. Browser validation improves feedback, but does not secure a real server submission.

Take the technique to your next job

Build a local form implementing these supplied rules only: [rules]. Use fictional fields/values, readable labels and specific error messages. Prevent external submission; a valid local result is a preview, not a saved service record. Include valid, empty, whitespace, threshold and awkward numeric/text cases with independent expected outcomes. Do not write tests that merely repeat your implementation's own answer. Provide actual runnable files and state which cases were really checked.
