test‑kit is a lightweight add‑on for the JavaScript testing frameworks **tape** or **tap** that enriches the test object (`t`) with a collection of handy utility functions—most notably data‑driven helpers like `t.table()` and `t.table_assert()`—plus string, array, UTF‑8 and other helpers. It’s aimed at developers who want clearer, more productive test suites and the ability to plug in their own custom assertions while keeping dependencies minimal.
