That’s what I was going to say, but I’m not sure that it’s a Rails
helper…the calculation rounds self. So I’m a bit confused.
If this is a module that you’re using to extend the behavior of
Numeric classes, just mix it in somewhere and write examples for the
class that got the mixin.

I prefer to test modules in isolation by mixing them into a stub in
the spec, in order to make it explicit that we’re describing the
module itself (not some other class), and to avoid dependencies on
that other class. For example:
describe ArtistsHelper do
before do
@artist = 123.456
class << @artist
include ArtistsHelper
end
end
it "should round stuff" do
@artist.round_to(1).should == 123.5
end
end
Granted, it looks a little awkward here since it looks like the module
is meant to be used with a Numeric, but in general I find this
approach to be pretty clean.

Isn’t it? That’s probably what I would infer if I read this code.
Is there any reason why you don’t do this?
@artist = Object.new.extend(ArtistHelper)
