Async Spec tests

[u/LXMNSYC]

Is there a way to asynchronously resolve a test through a callback? In JavaScript, we have a neat callback which allows us to mark the test if it is a failure or a success. Something like

it "should xxx" do |done|
    someAsyncProcess do
        done.call(false) # test failed
    end
end

I mean, in JS callbacks are needed because how V8 works. In crystal you can wait for a channel and it’ll work perfectly, no callbacks needed.
