## What it is
A comprehensive guide to modern Node.js testing featuring 50+ best practices, advanced topics like database, message queue, and contract testing, plus a fully worked example backend application. Authored by Yoni Goldberg and based on consulting experience with dozens of companies.

## Use cases
- learn node.js testing best practices
- how to write integration tests for express api
- test nodejs app with real database
- testing message queue flows in nodejs
- mocking external services in jest
- speed up nodejs test suite
- component testing patterns for backend apis

## When to choose
- you're building or testing Node.js backends and want battle-tested patterns
- you need guidance on integration/component testing with real databases and queues
- you want a runnable example app demonstrating the practices

## When to avoid
- you need a testing library or tool rather than guidance
- you're testing frontend code or non-JavaScript stacks
- you need formally licensed content - the repo has no license

## Facets
- artifact type: learning-resource
- maturity: active
- function: testing, e2e-testing, mocking, benchmarking
- domain: testing, backend, developer-tools, tutorials
