Spec2Test Engine Demo | Generate API Test Cases & Postman Collections from OpenAPI
🚀 Spec2Test Engine – Custom GPT for API QA Automation
In this demo, I showcase how Spec2Test Engine transforms OpenAPI (Swagger 2.x / 3.x) specifications into structured API test scenarios and ready-to-run Postman collections.
🔹 What this video covers:
• Uploading an OpenAPI YAML file
• Endpoint selection control
• Generating structured test scenarios
• Edge case and boundary validation
• Response body schema validation
• Authentication validation
• Organized Postman Collection (v2.1) generation
• Exporting CSV and JSON artifacts
Spec2Test Engine enforces:
✔ Deterministic scenario classification
✔ Schema-driven request generation
✔ Response body validation (not just status codes)
✔ Edge case handling with safe large-data controls
✔ Enterprise governance and traceability
This project explores how Custom GPTs can power real engineering workflows beyond simple chat use cases.
