Command Line Test Utility for Node.js

command-line-test is a focused Node.js utility library designed for performing integration tests against command-line interfaces and executables. Currently at version 1.0.10, it provides a unified API to execute shell commands and processes using Node.js's `child_process` module capabilities, including `fork`, `spawn`, `exec`, and `execFile`. The library simplifies the capture and analysis of standard output (`stdout`), standard error (`stderr`), and exit codes from executed commands, making it ideal for verifying CLI tool behavior. It supports asynchronous operations via Promises, traditional Node.js callbacks, and generator-based `yield` (often used with frameworks like `co` or `co-mocha`). Its primary differentiator is its straightforward approach to command execution and result parsing within a test environment, offering a stable and mature solution for CLI automation testing. The project appears to be in a maintenance phase, with infrequent updates since its stable 1.x release series.
