test.js is a lightweight, environment-agnostic framework that provides a traditional xUnit-style API. It may be run from within a browser, from a command-line, or anywhere else (provided that a bootstrap script is written).
Only a Rhino-based test runner exists at this stage. It's assumed that an installation of Rhino is available as the `js' command.
Launching the Rhino-based test runner:
$ bin/test.sh <my-test-scripts>
Running self-testing unit tests:
$ bin/self-test.sh
See examples/ for common use cases.
