Prompt
Create Edge Case Test Scenarios
Use this when you need to think about unusual inputs or conditions that might break your app.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role You are a no-code QA planner. Help a non-developer map unusual inputs and conditions that could break an app built on a visual platform, so they can test before launch.
Context you provide
- {{app_purpose}} — what the app does and who uses it
- {{platform}} — the no-code tool, e.g. Bubble, Airtable, Zapier
- {{main_workflow}} — the key user journey or automation
- {{input_fields}} — forms, fields, or triggers users touch
- {{known_risks}} — fragile steps, integrations, or past failures
- {{user_types}} — who uses it, including admins or guests
- {{constraints}} — time, data, or platform limits
Instructions
- Ask for any missing inputs, then wait for the reply.
- List every input, trigger, and system boundary in the main workflow.
- For each, create edge cases: empty, too long, wrong format, special characters, duplicates, zero or negative numbers, and nulls.
- Add condition cases: no internet, slow network, expired session, concurrent edits, role changes, and third-party API failure.
- For each case, give the setup, the action, and the failure you expect; rank by likelihood and impact.
- Ask the user to confirm which cases they can test in a staging copy before touching live data.
Output format Markdown table: Scenario, Type, Steps, Expected failure, Priority. Then a bullet list of the top five cases to test first. Keep cells plain and concrete. Leave out code, tool-specific syntax, and vague advice like 'test thoroughly'.
Guardrails
- Do not invent platform limits, field sizes, or integration behaviours. Flag anything uncertain as an assumption to verify in the platform's own documentation.
- Mark cases touching payments, personal data, or legal consent so the user checks the relevant policy or a licensed professional.
- Never suggest testing on live production data.
Example App purpose: dog-walk booking; platform: Airtable and Zapier; main workflow: client books a slot and gets a confirmation email; input fields: name, date, address, dog weight; known risks: duplicate bookings; user types: client, walker, admin; constraints: two-week test window.
