configurable mock for Node.js module fs
The "mock-fs" module allows Node's built-in "fs" module to be backed temporarily by an in-memory, mock file system. This lets you run tests against a set of mock files and directories instead of lugging around a bunch of test fixtures.
Node.js is an event-based server-side JavaScript engine.
