Mocking does not work

Testing RSpec
1

The spec

it “should expose a newly created logo as @logo” do
Logo.should_receive(:new).with({‘these’ =>
‘params’}).and_return(mock_logo(:save => true))
Logo.should_receive(:company=).with(mock_model(Company))
post :create, :logo => {:these => ‘params’}
assigns(:logo).should equal(mock_logo)
end

The code:

def create
@logo = Logo.new(params[:logo])
@logo.company = current_user.company
puts current_user.full_name
if @logo.save
flash[:notice] = ‘You logo was successfully uploaded.’
redirect_to logo_setting_path
else
render :action => logo_setting_path
end
end

And the error:

Spec::Mocks::MockExpectationError in ‘LogosController responding to POST
create
with valid params should expose a newly created logo as @logo’
Mock ‘Logo_1001’ received unexpected message :company= with
(#<Company:0x219a800
@name=“Company_1”>)

Question:
How could I mock a company= methond on Logo?

The instance of Logo should receive the company= method, not the class,
so:

@logo = mock_logo
Logo.should_receive(:new).and_return(@logo)
@logo.should_receive(:company=)

I would probably use stub! instead here and move this code into a before
block, and just keep the post and assigns lines in the it block.

Thanks for your reply, I did move the code to before

before(:each) do
Logo.stub!(:new).and_return(mock_logo(:save => true, :company= =>
nil))
end
