I have the code working for this but I wanted an opinion on making a patch.
I sometimes have the need to expect that a method will yield a block it's given. Usually this means something like this:
yielded = false
subject.method { yielded = true }
yielded.should == true
which is a bit tedious and ugly. My solution might be just as ugly, but I wanted to get feedback because it saves that tedious code.
subject.method(&should_yield)
I wrote a few methods, that when called, return an object with #to_proc that expects that the proc is called (or not called). I have the following forms available fairly simply:
subject.method(&should_not_yield)
subject.method(&should_yield_with(object))
# Expects 3 yields, one with each argument
[1,2,3].each(&should_yield_each(1,2,3))
I think this is a little cleaner and the code is very simple. I wanted to get an opinion on whether this is worth making into a patch.
