AI QA built for Python
Python web frameworks handle a lot of magic — Django ORM queries, FastAPI dependency injection, Flask context locals. VibeProof reads your Python codebase and generates test cases that cut through the abstraction to find real bugs.
What VibeProof tests
- View/endpoint testing — auth decorators, permission classes, request parsing edge cases
- Serializer validation — field-level constraints, nested object handling, partial update bugs
- ORM query correctness — N+1 queries, missing select_related, filter vs exclude logic
- Background task reliability — Celery/RQ task failure handling, retry logic, idempotency
- Middleware configuration — CORS settings, security headers, authentication pipelines
- Type safety — Pydantic model validation, optional field handling, enum constraints
Why this matters
Python's dynamic typing means bugs that TypeScript would catch at compile time only surface at runtime in Python. AI-generated Python code is especially prone to type confusion, missing None checks, and incorrect ORM query chains. VibeProof generates test cases that expose these issues before users do.
Example test cases
Django view without permission check
1.Send authenticated request as non-admin user to admin-only endpoint
2.Verify response status
3.Check if sensitive data is returned
Expected: 403 Forbidden. No admin data exposed to regular users.
FastAPI Pydantic model with optional fields
1.Send POST request with all optional fields omitted
2.Send POST request with optional fields set to null
3.Send POST request with optional fields set to empty strings
Expected: All three requests handled correctly without 500 errors.
FAQ
Does VibeProof work with Django REST Framework?+
Yes. VibeProof reads DRF serializers, viewsets, and permission classes to generate test cases for your API endpoints, including nested serializers and custom validation.
Does it support FastAPI?+
Yes. VibeProof understands FastAPI dependency injection, Pydantic models, and async route handlers. It generates test cases for path parameters, query parameters, and request body validation.
