Hi,
I've got trouble when describe infinite loop.
code snippet:
def start_loop
while true
data = self.server.handle_client
if data
self.manager.dispatch(data)
end
end
end
without the loop, it is easy to test the logic.
but how can I describe it to tell the developer ( me :-) ) that there
should be an infinite loop inside.
Here's a tip which Aslak gave me several months ago, and I find myself
repeating it in many different contexts on this mailing list:
One way is with dependency injection:
def start_loop(looping_infinitely = true)
while looping_infinitely
...
end
end
In your spec, you simply pass false (but production code can call the
method as if there is no option).
