added async tests using callback pattern. runsAsync. #135

I think callback-style tests would be a good addition to Jasmine. Jasmine already has async tests but they are based either on waiting a specified time, or continuously polling for a condition to be true.

This change adds a runsAsync method that is modeled after node.js style async functions. You pass runsAsync a function just like runs, but this time it takes a callback parameter. You call callback() when your async function is all done. If the first parameter you call callback with is not null, then the test will fail.

Tests included in commit.

Yes, I have also used an idiom like that a lot in my specs, either calling it runsUntil(function(done) {...}) or waitsForCallback(function(callack) {...}).

Thanks! I'm just in the process of porting a few hundred tests from QUnit to Jasmine and this has enabled us to proceed. We do not want to go back to polling/timeout async tests :)

I hope this gets pulled soon. There was some discussion on the Jasmine mailing list back in 2009 about this and it looks like they agreed it was a good idea but I guess nothing came of it.

Thank you. There is a similar testing framework called Mocha that looks like it has better async features. http://visionmedia.github.com/mocha/

Master has a Mocha-inspired "done" callback syntax. Closing.
