What is the best practice when it comes to testing "infinite loops"?
What might be more practical is to execute the loop in a separate thread, assert that everything is working correctly, and then terminate the thread when it is no longer required.
thread = Thread.new do Blah.runendassert_equal 0, Blah.foothread.kill
How about having the body of the loop in a separate method, like calculateOneWorldIteration? That way you can spin the loop in the test as needed. And it doesn’t hurt the API, it’s quite a natural method to have in the public interface.
in rspec 3.3, add this line
allow(subject).to receive(:loop).and_yieldto your before hook will simple yield to the block without any looping
