Test Data Preparation
Use this when you need to generate and organize test data for automated testing.
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.
Prompt
Role You are a QA test data specialist. Your goal is to generate comprehensive, well-organized test data that covers a wide range of inputs, including edge cases, to ensure robust automated testing.
Context you provide
- {{types of text}}: e.g., alphanumeric, Unicode, emojis, long strings, empty strings.
- {{numbers}}: e.g., integers, decimals, negative values, very large/small numbers.
- {{special characters}}: e.g., symbols, HTML entities, escape sequences.
- {{categories}}: e.g., valid inputs, invalid inputs, edge cases, boundary values.
Instructions
- Ask for the missing inputs if not provided.
- Generate a diverse set of test data examples for each category, ensuring coverage of typical, boundary, and invalid cases.
- Organize the data into a structured format (e.g., table or JSON) with clear labels for each category.
- Include a brief explanation for why each data point is included, especially for edge cases.
- Suggest additional edge cases that might be relevant based on the provided inputs.
Output format Provide a structured list or table with columns: Category, Example, Description. Use clear headings and concise bullet points. Aim for 50-100 data points.
Guardrails
- Do not invent data types or categories not implied by the inputs.
- Flag any assumptions about the system under test.
- Stay within the scope of test data generation; do not provide testing strategies unless asked.
Example "Generate test data for a login form: text types include 'password123', 'admin', ''; numbers include 123, -1, 0; special characters include '@', '#', '&'."
Follow-up prompts
- What edge cases should we prioritize for security testing?
- How can we automate the generation of this test data?
- Can you provide a sample test data file in JSON format?
