rspec users - May 2012 - alternate way to stub out I18n translations?

Hi,

I''ve run into a bit of a snag...

I have a method like this

class Thing
  def bar
    I18n.t("waka.waka", { :fozzy => "bear" })
  end
end

And I was trying to make a test that did:

describe "#bar" do
  it "translates like a mo fo" do
    I18n.stubs(:t).with("waka.waka", { :fozzy => "bear"
}).returns "hooray!"
    subject.bar.should == "hooray!"
  end
end

However running this test gives me:

     Mocha::ExpectationError:
       unexpected invocation: I18n.t(:user_subject, {:scope => [:devise,
:mailer, :confirmation_instructions], :default => [:subject,
''Confirmation instructions'']}

...

Which is obviously because when I stub the t method, I am killing any
previous behavior..........  So, I am quite confused what to do here.

If I try to just be more generic and do:

describe "#bar" do
  it "translates like a mo fo" do
    I18n.stubs(:t).returns "hooray!"
    subject.bar.should == "hooray!"
  end
end

Then I get a whole different weird error:

     Failure/Error: let(:notification) { new_notification(:notifiable =>
create_offer, :action => "made") }
     ArgumentError:
       wrong number of arguments (4 for 5)

...

But I don''t want to be generic like that anyway--- So I am wondering
what can I do to solve this?

Does any one know of a way to temporarily add an entry into my en.yml
locale dynamically?  In other words, so that instead of stubbing I could
just do something like:

I18n.t("waka")[:waka] = "hooray!"

and then in code can still access

I18n.t("waka.waka")..  But that doesn''t work, and I am not
sure how to
pull that off...  Any help would be greatly appreciated.

I usually do something like this in the before filter

   en = { :my => { :stuff => ''things'' } }
   I18n.backend.store_translations(:en, en)
