Minimal Test Runner Command Builder

The `test-cmd` package is a minimalist Node.js utility designed to facilitate the creation and execution of simple command-line test runners. Released with its latest stable version 1.7.0 over eight years ago, this package is built entirely on CommonJS modules and leverages older dependencies like `optimist` for argument parsing, `tape` for test assertions, and `through` for stream manipulation. Its primary function is to wrap shell commands and integrate them into a testing flow, making it suitable for black-box testing of command-line interfaces. Due to its age and lack of recent maintenance, it does not support modern JavaScript features like ESM or `async/await` and is generally considered superseded by contemporary testing frameworks. It has an infrequent release cadence, with its last update being many years ago, indicating it is no longer actively maintained.
