Generate Synthetic Data for Negative Testing

A well-structured mind map can help identify and categorize different types of negative tests. Break down test cases into primary categories like Invalid Data TypesMalformed Requests, and Boundary Values.

  1. Invalid Data Types
    • String in place of integer (e.g., “Thirty” for age)

  2. Malformed Requests
    • Missing fields
    • Incorrectly nested JSON objects
  3. Boundary Value Tests
    • Entering values slightly above or below expected range

Here’s an example mind map layout that can be a helpful guide for visualizing edge cases:
