JSpec is a extremely small, yet very powerful testing framework. Utilizing its own custom grammar and pre-processor, JSpec can operate in ways that no other JavaScript testing framework can. This includes many helpful shorthand literals, a very intuitive / readable syntax, as well as not polluting core object prototypes.

JSpec can also be run suites in a variety of ways, such as via the terminal with Rhino support, via browsers using the DOM or Console formatters, or finally by using the Ruby JavaScript server which runs browsers in the background, reporting back to the terminal.
