Testing for your Cline-built JavaScript app

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

Cline issues we find in JavaScript projects

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

highSecurity

Unsupervised file modifications

Cline modifies multiple files autonomously. Without careful review, security-critical changes like auth configuration or API permissions can go unnoticed.

highSecurity

Dependency installation without audit

Cline installs npm packages autonomously without checking for known vulnerabilities, malicious packages, or unnecessary additions.

mediumBugs

Cascading changes across files

Cline's multi-file edits sometimes introduce bugs in files that weren't the focus of the change, causing regressions in unrelated features.

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.
