proxyquire
Proxies Node.js require to allow easy overriding of dependencies during testing without modifying source code.
What is proxyquire?
Proxyquire is a Node.js library that proxies the `require` function to allow easy stubbing and mocking of dependencies during unit testing. It solves the problem of isolating modules by letting developers override specific dependencies without altering the original source code, ensuring tests are focused and reliable.
Node.js developers and testers who need to write isolated unit tests for modules with external dependencies, particularly those working in test-driven development (TDD) or behavior-driven development (BDD) environments.
Developers choose Proxyquire because it requires no changes to production code, works with any mocking framework, and provides fine-grained control over dependency behavior while keeping non-overridden methods intact, making it a flexible and unobtrusive testing tool.
