thanks pat, it''s still a good primer ;)
I''m getting a better handle at it, but I''m still confused as
to how to
test assigment of associated objects. for instance, how do I test this
(using attachment_fu)?
@work.image = @image

I see. I had gotten to trying the first way you suggested (haven''t
tried the second yet):
it "should assign an image to the work" do
@work.should_receive(:image=).with(@image)
end
but I got the following error:
should assign an image to the work
Mock ''Work_1002'' expected :image= with (#<Image:0x19e8094
@name="Image_1001">) once, but received it 0 times
though in the actual controller @work does receive it:
def create
@work = @category.works.build(params[:work])
@image = Image.new(params[:image])
@work.image = @image
respond_to do |format|
if @image.save and @work.save
flash[:notice] = ''Work was successfully created.''
format.html { redirect_to admin_category_work_path(@category, at work) }
else
format.html { render :action => "new" }
end
end
end
I''m sure I''m missing something here...

Are u stubbing Image.new and returning @image?? otherwise I think the error is accurately complaining that it did not receive :image= with the object that you have said.

And the other thing I am not seeing .... you are calling create somewhere in the spec?

You need to take control of the objects if you want to make interaction verifications of them. Read through some of the documentation starting at http://rspec.info/documentation/mocks/ and see if you can grok it. Feel free to ask more questions if you run into trouble. Pat
should have posted the code, sorry about that :) http://pastie.caboo.se/165708 I was actually posting to :create, but hadn''t added do_post() to the example :P adding it solved this specific problem, thanks. hope the pastie helps another newb out 2008/3/13, Shane Mingins <smingins at elctech.com>:> And the other thing I am not seeing .... you are calling create > somewhere in the spec? > > Always a good idea to post all the code :-) > > > Cheers > Shane > > > On 14/03/2008, at 12:55 PM, Oliver Barnes wrote: > > > > I see.
