SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables comprehensive testing of Nuxt 3 / Nitro applications by providing a framework for realistic integration tests against a real PostgreSQL database, with transactional rollback to ensure deterministic isolation.

Core Features & Use Cases

End-to-end testing of Nuxt server API handlers and frontend components using a real DB.
Transaction-based isolation that auto-rolls back between tests for fast, repeatable results.
Example scenarios include API handler validation, page data fetching, and component testing with mountSuspended.

Quick Start

Install and configure vitest with globalSetup to reset and migrate the test DB, then write tests using test-utils primitives and run the suite.

FAQPage Schema

How do I test Nuxt 3 API handlers against a real PostgreSQL database?▼

You can test Nuxt 3 API handlers against a real PostgreSQL database by using Vitest with Nuxt test-utils to validate endpoints, while relying on transactional rollback for test isolation.

What is transactional rollback isolation in Vitest database testing?▼

Transactional rollback isolation in Vitest wraps each test in a database transaction that is automatically rolled back afterward, ensuring deterministic and repeatable test runs without manual data cleanup.

Does nitro-testing work with frontend components and mountSuspended?▼

Yes, nitro-testing supports frontend component testing using mountSuspended, allowing you to test Nuxt page data fetching and component behavior with the same real database and isolated rollback environment.

How do I configure Vitest globalSetup for Nuxt Nitro database testing?▼

Configure Vitest globalSetup to reset and migrate your test database before running the suite, then write isolated test files using Nuxt test-utils primitives to validate server handlers and components.

What's the best way to get deterministic results when testing Nitro server endpoints?▼

Using a real PostgreSQL database with transaction-based rollback is the best way to achieve deterministic results, ensuring every Nitro server endpoint test starts with a clean, isolated data state.

Why does my Nuxt test suite leak data between integration tests?▼

Data leaks between integration tests occur without transactional rollback; applying this Skill's transaction-based isolation auto-rolls back database changes after each test, preventing state leakage.
