API Test Case Generator – REST & Integration QA

Our API test case generator creates structured cases for REST endpoints—valid payloads, error responses, auth, rate limits, and boundary conditions—from your requirements or OpenAPI-style descriptions.

What you get

  • HTTP method, path, headers, and body scenarios
  • Expected status codes and response validation
  • Negative cases: invalid tokens, malformed JSON, missing fields
  • Edge cases: pagination, limits, idempotency

How to use it

  1. Paste an API user story or endpoint description on the Generate tab.
  2. Enable "Include API Test Cases" when uploading documents.
  3. Review generated cases and export to CSV, Excel, or Jira.
