Testing for your GitHub Copilot-built JavaScript app

Expert testing for JavaScript apps built with GitHub Copilot. We audit GitHub Copilot-generated JavaScript code for testing issues. From $19.

GitHub Copilot issues we find in JavaScript projects

Problems specific to GitHub Copilot's code generation patterns when building JavaScript apps.

highSecurity

Insecure code patterns from training data

Copilot sometimes suggests patterns from its training data that are known to be insecure — like using eval(), innerHTML, or outdated crypto functions.

highSecurity

Hardcoded secrets in suggestions

Copilot occasionally suggests placeholder API keys or credentials that look real and get committed to version control.

lowCode Quality

Inconsistent code style across files

Different completions use different patterns — sometimes callbacks, sometimes async/await, sometimes .then(). The codebase becomes inconsistent over time.

JavaScript testing issues we check for

Testing-specific JavaScript problems that need attention before production.

security

Prototype pollution

AI-generated code merges user-supplied objects into prototypes via Object.assign or spread operators without sanitization, enabling property injection attacks.

bugs

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.

bugs

Unhandled promise rejections

Async functions without try/catch or .catch() handlers cause unhandled rejection warnings and silent failures in production.
