Stub methods on objects, not modules. The method can be one that
*comes from* a module, but you need to stub it on the specific object
that is at play in the example.
module Foo
def do_something
end
class Bar
include Foo
end
describe Bar do
before(:each) do
@bar = Bar.new
@bar.stub(:do_something)
end
...
end
