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.
