## What it is
fetch-mock is a JavaScript library for mocking HTTP requests made with the fetch API, with an intuitive API for routing mocks based on request criteria. It runs in environments from Node.js to service workers and is compatible with most testing frameworks.

## Use cases
- mock fetch requests in unit tests
- simulate different HTTP responses based on URL or criteria
- test code that calls the fetch API in node
- intercept fetch calls in service workers
- stub network responses for frontend testing

## When to choose
- your code uses the fetch API and you need deterministic tests
- you need fine-grained routing of mocked responses by URL, method, or other criteria
- you need a mock that works across node, browsers, and service workers

## When to avoid
- your code uses axios or another XHR-based client rather than fetch
- you need full end-to-end tests against a real server
- you want automatic request recording/replay rather than hand-written mocks
