SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Write Vitest tests for MongoDB repository implementations. This Skill helps teams validate their MongoDB data access layers by providing a ready-to-use test scaffold and an in-memory MongoDB setup.

Core Features & Use Cases

  • In-memory MongoDB environments for safe, fast tests
  • Vitest-based test scaffolds with global setup and per-test hooks
  • Clear patterns for CRUD-style repository tests across entities

Quick Start

Run the Vitest suite for tests/repositories/{entity-name}.mongodb.repository.test.ts to begin validating your MongoDB repositories.

FAQPage Schema
How do I test MongoDB repository implementations without a live database?

You can test MongoDB repository implementations without a live database by using an in-memory MongoDB instance. This provides a fast, isolated environment for safely validating data access layers and CRUD operations.

How do I configure Vitest with globalSetup and setupFiles for database testing?

Configuring Vitest for database testing involves setting up a globalSetup to initialize a test database and setupFiles for per-test hooks. This scaffold ensures a clean test database state before running repository validations.

What is the best way to write CRUD tests for TypeScript repositories?

The best way to write CRUD tests for TypeScript repositories is using a Vitest-based scaffold with an in-memory database. This setup provides clear patterns for testing data access layers across multiple entities safely.

Can I use mongodb-memory-server with Vitest for repository integration tests?

Yes, you can use mongodb-memory-server with Vitest for repository integration tests. This combination creates a mock-like test helper environment, allowing you to run tests quickly without modifying a persistent database.

Why do my MongoDB repository tests fail when run in parallel?

MongoDB repository tests may fail in parallel if they share a database state. Using an in-memory MongoDB setup with proper Vitest per-test hooks ensures test isolation, preventing data collisions between parallel test runs.
