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.
