Testing for your Cursor-built FastAPI app
Expert testing for FastAPI apps built with Cursor. We audit Cursor-generated FastAPI code for testing issues. From $19.
Cursor issues we find in FastAPI projects
Problems specific to Cursor's code generation patterns when building FastAPI apps.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
FastAPI testing issues we check for
Testing-specific FastAPI problems that need attention before production.
Missing authentication on endpoints
API routes that handle sensitive data or actions without any auth middleware — Depends() for authentication is simply not included in the route definition.
No CORS configuration
CORSMiddleware either missing (blocking all cross-origin requests) or set to allow_origins=['*'] (allowing any website to call your API).
Pydantic models without validation constraints
Request models that accept any string length, any number range, and any format. No Field() constraints, so invalid data flows through your system.

Frequently asked questions
Can you testing my Cursor-built FastAPI app?
Yes. We regularly handle testing for FastAPI projects built with Cursor. We understand Cursor's code patterns and the specific FastAPI issues they introduce. Our review covers the full stack from frontend to backend.
What FastAPI testing issues does Cursor typically create?
Common testing issues in Cursor-generated FastAPI code include: exposed api keys in client code, missing input validation on api routes, unhandled async errors. On the FastAPI side, we often find: missing authentication on endpoints, no cors configuration, pydantic models without validation constraints.
