## What it is
A Node.js library that proxies the require function so dependencies can be overridden with stubs or mocks during testing without modifying the code under test. It is mocking-framework agnostic and lets non-overridden methods behave like the original.

## Use cases
- stub node modules in unit tests
- override dependencies without changing production code
- mock require calls in javascript tests
- inject test doubles into nodejs modules
- partially mock a module while keeping other methods real
- prevent call-thru to original dependencies during tests

## When to choose
- you test CommonJS Node.js code that uses require and want unobtrusive dependency stubbing
- you want to use your existing mocking/stubbing library with require overrides
- you need to stub only some methods of a dependency and leave the rest intact

## When to avoid
- you write ES modules with import statements instead of CommonJS require
- you use a bundler-based test setup (browser/client code) rather than Node.js
- you prefer modern test runners with built-in module mocking
