AI Test Case Generator
Turn a user story and acceptance criteria into structured QA test cases, including positive, negative, and edge scenarios. It helps testers and developers cover cases they might otherwise miss.
AI Test Case Generator
Generate structured software test cases from requirement text with positive, negative, and edge-case coverage.
Generated Test Cases
Generated output will appear here after you run generate test cases.
Coverage is where teams slip
Most teams write the obvious 'happy path' tests and forget the cases that actually break software: empty inputs, maximum values, invalid formats, and unexpected sequences. This tool is built to push past the happy path, generating negative and edge scenarios from your criteria so the suite covers more than the demo flow.
The quality of the output tracks the quality of your acceptance criteria. Clear, specific criteria produce specific test cases; vague criteria produce vague tests that still need a human to make them concrete.
From draft to real suite
Use the generated cases as a checklist to refine.
- Add the exact expected results and test data your application uses.
- Prune cases that do not apply and add domain-specific ones the AI could not know.
- Map each case back to an acceptance criterion so you can prove coverage.

FAQs
Does it replace a QA engineer?▼
No. It speeds up the first draft and reduces missed scenarios, but a tester still needs to add real data, expected results, and domain knowledge, and to judge which cases matter most.
Will it find edge cases I missed?▼
Often, yes - generating negative and boundary scenarios is one of its main strengths. It is a useful prompt against tunnel vision, though it is not exhaustive.
What input gives the best test cases?▼
Clear acceptance criteria with specific, measurable conditions. The more concrete your story, the more concrete and useful the generated cases.
Is my user story sent to a model?▼
Yes. The story and criteria are processed by a language model, so avoid including confidential product details.
