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
