Testing for your Supermaven-built JavaScript app
Expert testing for JavaScript apps built with Supermaven. We audit Supermaven-generated JavaScript code for testing issues. From $19.
Supermaven issues we find in JavaScript projects
Problems specific to Supermaven's code generation patterns when building JavaScript apps.
Fast completions accepted without review introduce subtle type errors
Supermaven's speed is its core advantage, but it encourages accepting completions quickly. TypeScript type errors, incorrect function signatures, and wrong argument orders frequently slip through when developers tab-accept completions at high speed.
Security-sensitive code patterns completed without security review
In security-critical code paths like authentication, token validation, and database queries, Supermaven's completions can introduce subtle vulnerabilities — such as completing a SQL query without parameterization or missing a signature verification step.
Existing codebase anti-patterns replicated across new files at high velocity
Supermaven learns from your codebase, which means bad patterns — deprecated APIs, insecure functions, or architectural mistakes — get propagated to new code rapidly due to how quickly completions are accepted.
JavaScript testing issues we check for
Testing-specific JavaScript problems that need attention before production.
Prototype pollution
AI-generated code merges user-supplied objects into prototypes via Object.assign or spread operators without sanitization, enabling property injection attacks.
Loose equality comparisons
Using == instead of === leads to type coercion bugs where '0' == false, null == undefined, and other non-obvious truthy/falsy comparisons cause silent logic errors.
Unhandled promise rejections
Async functions without try/catch or .catch() handlers cause unhandled rejection warnings and silent failures in production.

Frequently asked questions
Can you testing my Supermaven-built JavaScript app?
Yes. We regularly handle testing for JavaScript projects built with Supermaven. We understand Supermaven's code patterns and the specific JavaScript issues they introduce. Our review covers the full stack from frontend to backend.
What JavaScript testing issues does Supermaven typically create?
Common testing issues in Supermaven-generated JavaScript code include: fast completions accepted without review introduce subtle type errors, security-sensitive code patterns completed without security review, existing codebase anti-patterns replicated across new files at high velocity. On the JavaScript side, we often find: prototype pollution, loose equality comparisons, unhandled promise rejections.
