How it works

1

Describe your core flow

Check every characteristic that applies to the one user flow you're scoping — free-text input, file upload, payment, and so on.

2

Get a rule-based checklist

Each selected characteristic contributes a curated set of edge cases from a fixed, deterministic rule set — not a random or AI-generated guess.

3

Split by priority

Cases are tagged must-handle (risk of visible breakage or data loss) or can-defer (safe to note and revisit after launch).

Frequently asked questions

Is this an exhaustive QA plan?

No. It's a curated starting checklist based on common flow patterns, meant to catch the edge cases most MVPs miss — not a substitute for a full test plan.

How is must-handle vs. can-defer decided?

Each case is tagged by how likely it is to cause visible breakage or data loss if skipped (must-handle) versus a rare, lower-stakes polish gap (can-defer).

Can I select more than one characteristic?

Yes — most real flows combine several (e.g. a payment step that's also a multi-step form). Select every characteristic that genuinely applies.

Does this replace writing test cases?

No. Pair it with the Acceptance Criteria Writer or a QA test case tool to turn each edge case into something testable.
