What is the benefit of the transaction rollback pattern?

It allows tests to interact with a real PostgreSQL database for maximum accuracy while remaining as fast as mocks, as it reverts changes instantly instead of performing slow table truncations.

Does this skill support both backend and frontend testing?

Yes, it provides comprehensive guidance for testing Nitro API handlers (backend) as well as Vue components, pages, and composables (frontend).

How does this skill handle Nuxt auto-imports in Vitest?

It provides setup file patterns that stub common Nuxt/Nitro auto-imports such as defineEventHandler, createError, and useDatabase, ensuring your tests run smoothly in a Node environment.

Can I use this with query builders like Kysely or Prisma?

Absolutely. While the examples use Kysely, the transaction-bound database fixture pattern is adaptable to any query builder or ORM that supports transactional access.

Security & Testing

Streamlines testing for Nuxt 3 and Nitro applications using transactional PostgreSQL isolation and advanced component testing patterns.

About

This skill provides a robust framework for end-to-end and unit testing within the Nuxt 3 and Nitro ecosystem. It focuses on a high-performance database isolation pattern where real PostgreSQL transactions are automatically rolled back after each test, eliminating the need for slow table truncations while maintaining data integrity. For the frontend, it offers standardized patterns for testing Vue components, pages, and composables using @nuxt/test-utils and mountSuspended. By providing mock event helpers, transaction-bound factories, and stubs for Nuxt auto-imports, this skill ensures developers can write fast, reliable, and deeply integrated tests for both their API handlers and UI logic.
