CLI tool for building browser extensions

#!/usr/bin/env node

/**
 * @name xt-test
 * @module
 * @public
 *
 * @description
 *
 * ```text
 * xt-test [--pattern] [--coverage] [--watch]
 * ```
 *
 * This command will run project unit tests located in `./test` directory.
 *
 * Command sets up extension unit testing environment with ES6 syntax support that is pre-initialized
 * with [mocha](https://mochajs.org/), [chai](https://www.chaijs.com/) and expect.
 * [nyc](https://www.npmjs.com/package/nyc) is used for computing code coverage.
 * The following browser APIs are also initialized: `window`, `document`, `chrome`.
 * Window is setup using [jsdom-global](https://www.npmjs.com/package/jsdom-global) and
 * chrome using [sinon-chrome](https://www.npmjs.com/package/sinon-chrome).
 *
 * You may extend this test environment within a single project. This is simply the base setup
 * for running unit tests. Or create your own testing environment at project level if this is
 * not suitable.
