foounit

A functionally scoped BDD style test framework that runs everywhere.

Key features:

• Asyncronous test running
• Out of the box support for multiple javascript host environments: node.js, major browsers, Adobe AIR, The Ruby Racer
• BDD style test running
• A simple API

Contrived Example

var MyLib = foounit.require(':src/my_lib');

foounit.add(function (kw){ with(kw){
  describe('when something happens', function (){
    var myLib;
    before(function (){
      myLib = new MyLib();
    });

    it('does something awesome', function (){
      expect(myLib.someFunc()).to(equal, 'foo');
    });
  });
}});

Other Alternatives

foounit isn't for you?

There's a lot of great unit testing frameworks for javascript these days. It's more important that people are testing their code than it is that people use foounit.

Some notable alternatives are:

• jasmine (This is also a rewrite of Screw Unit)
• shoulda.js (BDD with different syntax)
• vows (BDD with different syntax)
• logan (Cross environment unit testing)

Greetz

• mde - for providing good ideas
• peterbraden - for identifying problems with foounit's first iteration
• nathansobo - for rewriting Screw Unit while I was at Grockit which got me this far
• Alex Russell and James Burke - for being a sounding board for synchronous loader ideas
• jasmine for beating me to the punch :) and also providing a better API than I originally had
