**Project Summary:** `data-driven` is a small Node.js library that extends the Mocha testing framework with built‑in support for parameterized (data‑driven) tests. It lets developers define a data set as an array of objects and automatically generates a separate test case for each item, inserting data values into test titles and passing the current data object to the test function—useful for both synchronous and asynchronous tests. Target audience: JavaScript developers who write unit tests with Mocha and want a concise way to run the same test logic against multiple input scenarios.
