Using Grammatical Evolution to Discover Test Payloads: A New Frontier in API Testing

"What if your test cases evolved on their own, like digital bacteria, probing your API for weaknesses while you slept?" Welcome to the Strange Future of API Testing Grammatical Evolution (GE), when fused with Genetic Algorithms (GA), opens up a beautifully chaotic new approach to payload discovery. This post introduces a fully containerized system that mutates and evolves API payloads using the DEAP Python library to hunt for: Validation failures Authentication edge cases Timeouts and memory issues Vulnerabilities (SQLi, auth bypass, broken logic)

  • Authentication edge cases
  • Timeouts and memory issues
  • Vulnerabilities (SQLi, auth bypass, broken logic)
