## What it is
A Node.js library that intercepts require() calls so mocks or substitutes can be injected in place of real modules during unit testing. It is not a mocking framework itself but a helper for hooking mocks from any framework into the module loading system.

## Use cases
- inject mocks into require calls for unit tests
- replace node modules with test doubles
- stub dependencies in node.js unit tests
- isolate code under test from its dependencies
- control the require cache during testing

## When to choose
- you need to mock modules loaded via require in Node.js
- you want a framework-agnostic way to wire in test doubles
- you need fine control over the module cache in tests

## When to avoid
- you are testing ES modules with import statements
- you want a full mocking framework with assertion helpers
- you need an actively developed solution with modern Node support

## Facets
- artifact type: library
