setImmediate shouldn't be used, since it means we will never be able to run these tests in a real browser. https://developer.mozilla.org/en-US/docs/Web/API/Window/setImmediate
Consider setTimeout instead.

setTimeout is mocked by jest, don't know how to simulate asynchronous in jest

I don't see a problem with this? You guys should upgrade to jasmine2 so you can use the done feature of jasmine2 for async testing. Otherwise waitsFor is fine, just ugly API. You can also do jest.runAllTimers() to advance them manually – that way you can get rid of the waitsFor.

runAllTimers run function provided to setTimeout synchronously. This test case needs asynchronization

what kind of async? You can also do jest.runAllImmediates.
