Testing for your Cursor-built React app
Expert testing for React apps built with Cursor. We audit Cursor-generated React code for testing issues. From $19.
Cursor issues we find in React projects
Problems specific to Cursor's code generation patterns when building React 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.
React testing issues we check for
Testing-specific React problems that need attention before production.
XSS via dangerouslySetInnerHTML
AI tools use dangerouslySetInnerHTML to render dynamic content without sanitization, allowing script injection.
Exposed environment variables
Sensitive keys placed in NEXT_PUBLIC_ or REACT_APP_ prefixed variables, making them visible in the browser bundle.
Unhandled promise rejections
Async operations in useEffect without proper error handling crash silently or show raw error messages.
