This is awesome news (to me)! Thank you for sharing.
For anyone that wants to use Jasmine 2 I created atom-jasmine2-test-runner.
atom-jasmine2-test-runner you can choose which helpers you want to include.
The way Atom uses to get around this is to call
jasmine.useRealClock() to unSpy all of the mocked clock functions or use
window.advanceClock(ms) to artificially advance the mocked clock and call the
setTimeout/setInterval function without actually waiting for the timeout.
