Beautiful assertion library.
No verbosity: We don't want
Helpful error messages: When things go wrong, Alright should do its best to show you exactly what's wrong and how you might fix it.
Test-framework agnostic: Alright should work with anything that expect Errors to be thrown when assertions fail.
Work with older Browsers: Some people still need to support old IEs, Alright should work on them.
Using the Sweet.js macros:
// for macros to work, you need to use 'alright' as your identifiervar alright =// simple assertionsa + bnot a + b// anything goes assertionsb shouldb should not// asynchronous assertions with pure fantasy-land monads, or Promises/A+b willb will not
var _ =// Use verify for synchronous assertions____// use verifyFuture for monadic Futures, and verifyPromise for Promises/A+__

This library assumes an ES5 environment, but can be easily supported in ES3 platforms by the use of shims. Just include es5-shim :)
