How do I estimate the hours needed to cover untested scenarios by risk class?

Use distinct identified scenarios and expected authoring time per missing test. Already covered scenarios count once.

Where the idea came from

Estimate the hours needed to cover untested scenarios by risk class. The demonstration requires actual execution before work can be marked complete. Benchcraft designed this tool’s inputs, decision rule and example for this office task.
