Testing for your v0-built Next.js app
Expert testing for Next.js apps built with v0. We audit v0-generated Next.js code for testing issues. From $19.
v0 issues we find in Next.js projects
Problems specific to v0's code generation patterns when building Next.js apps.
No backend or API integration
v0 generates frontend components only. There's no database connection, API routes, authentication, or server-side logic — all of which need to be built separately.
Static mock data instead of real data
Components use hardcoded mock data for display. Connecting them to real APIs requires significant additional work to handle loading states, errors, and data fetching.
Components not connected to state
Interactive elements like forms, filters, and toggles look correct but don't actually do anything. State management needs to be wired up manually.
Next.js testing issues we check for
Testing-specific Next.js problems that need attention before production.
Unprotected API routes
Next.js API routes and server actions without authentication checks, allowing anyone to call them directly.
Server action data exposure
Server actions that return sensitive data to the client or don't validate user permissions before modifying data.
Incorrect middleware configuration
Auth middleware that doesn't cover all protected routes, uses wrong matchers, or can be bypassed with URL manipulation.

Frequently asked questions
Can you testing my v0-built Next.js app?
Yes. We regularly handle testing for Next.js projects built with v0. We understand v0's code patterns and the specific Next.js issues they introduce. Our review covers the full stack from frontend to backend.
What Next.js testing issues does v0 typically create?
Common testing issues in v0-generated Next.js code include: no backend or api integration, static mock data instead of real data, components not connected to state. On the Next.js side, we often find: unprotected api routes, server action data exposure, incorrect middleware configuration.
How much does testing cost for a v0 Next.js project?
Start with our $19 automated audit to get a prioritized list of issues. For hands-on testing work on v0-built Next.js projects, we provide a fixed quote after reviewing the audit results. No surprises.
