Testcase Coverage & Edge Cases Prompt - Usage Guide

This guide explains how to use the provided QA prompt to maximize your project’s test coverage, especially for negative and edge cases.

How to Use the Prompt

  1. Copy the Prompt:
    Copy the prompt from PROMPT.md and provide it to your QA team or AI tool, along with your project context.

  2. Generate Testcases:
    The QA or AI will generate a comprehensive set of testcases, covering unhappy paths, edge cases, invalid input, timeouts, unauthorized access, and non-ideal user behaviors.
    All testcases will be organized by category and written in the format:
    • Verify that user can’t sign up without filling the mandatory fields
    • Verify the behaviour when user who already had an account trying to register again

  3. Review Techniques:
    The prompt instructs to apply three expert QA techniques (such as Boundary Value Analysis, Error Guessing, and Exploratory Testing) and to review the testcases twice, ensuring completeness and quality.

  4. Check Output:
    All generated testcases will be saved in a separate file named testcases_checklist.md for easy review and tracking.

Best Practices

  • Provide Project Context:
    The more details you provide about your project, the more relevant and thorough the testcases will be.

  • Iterative Review:
    Use the expert review techniques as described in the prompt to iteratively improve the testcases.

  • Collaborate:
    Share the testcases_checklist.md file with your team for further feedback and continuous improvement.

  • Keep Updated:
    Update the checklist as your project evolves or new features are added.

Benefits

  • Improved Coverage:
    Ensures all negative, edge cases, and non-ideal scenarios are tested.
  • Reduced Risk:
    Helps catch bugs that might otherwise go unnoticed.
  • Clear Documentation:
    Keeps your testcases organized and easy to maintain.

By following this guide and using the prompt, you can significantly improve the reliability and robustness of your project through better test coverage.
