AI QA built for SaaS
SaaS products have more surface area than any other type of application. Multi-tenant data isolation, subscription billing, OAuth token lifecycle, webhook processing, role-based access — each one is a category of bugs that can lose customers. VibeProof tests all of them.
What VibeProof tests
- Tenant isolation — cross-workspace data leakage, shared resource conflicts, org-level permissions
- Billing and subscriptions — plan limits, upgrade/downgrade flows, trial expiry, failed payment handling
- OAuth integrations — token refresh, scope changes, revocation handling, concurrent connection management
- Webhook reliability — signature verification, idempotency, retry handling, payload validation
- RBAC — role hierarchy, permission inheritance, admin escalation, invite/remove flows
- Audit logging — sensitive action tracking, PII handling, compliance requirements
Why this matters
SaaS bugs don't just break features — they break trust. A data leak between tenants, a billing error, or a broken integration costs you the customer forever. VibeProof generates the test cases that protect your most critical flows.
Example test cases
OAuth token refresh race condition
1.Set integration token to expire in 1 second
2.Trigger two concurrent API calls that both need the token
3.Verify both calls succeed
4.Check that only one refresh was performed
Expected: Both calls succeed. Token refreshed once, not twice. No duplicate refresh errors.
Plan downgrade with over-limit usage
1.Create 10 projects on Pro plan (limit: unlimited)
2.Downgrade to Starter plan (limit: 1 project)
3.Verify existing projects are not deleted
4.Verify new project creation is blocked
Expected: Existing projects preserved but read-only. New creation blocked with upgrade prompt.
FAQ
Does VibeProof test multi-tenant isolation?+
Yes. VibeProof generates test cases that specifically attempt cross-tenant data access — querying resources with IDs from other workspaces, accessing shared endpoints without proper scoping.
Can it test billing flows?+
VibeProof generates test cases for subscription lifecycle events — trial expiry, plan changes, failed payments, cancellation, and refund handling.
