Testing Email w/ Pony and RSpec in Rails 3.1

I tried using this How do I test Pony emailing in a Sinatra app, using rspec? to test a Rails 3.1 app sending emails. The sending works fine, but I'm having a hard time getting the tests to work. Here's what I have so far ...

spec/spec_helper.rb

config.before(:each) do
    do_not_send_email
end
.
.
.
def do_not_send_email
    Pony.stub!(:deliver) # Hijack to not send email.
end

and in my users_controller_spec.rb

it "should send a greeting email" do
    post :create, :user => @attr
    Pony.should_receive(:mail) do |params|
        params[:to].should == "nuser@gmail.com"
        params[:body].should include("Congratulations")
    end
end

and I get this ...

Failures:

1) UsersController POST 'create' success should send a greeting email Failure/Error: Pony.should_receive(:mail) do |params| (Pony).mail(any args) expected: 1 time received: 0 times # ./spec/controllers/users_controller_spec.rb:121:in `block (4 levels) in '

It looks like Pony's not getting an email, but I know the real email is getting sent out.

Any ideas?

Here's what I finally ended up with for the test ...

it "should send a greeting email" do
    Pony.should_receive(:deliver) do |mail|
        mail.to.should == [ 'nuser@gmail.com' ]
        mail.body.should =~ /congratulations/i
    end
    post :create, :user => @attr
end

The Pony.should_rececieve needs :deliver (not :mail), the do/end was changed a bit, and the post was done after the setup.

Hope this helps someone else.
