To do this, I've typically just add the HTTP_ACCEPT header. I can't
remember where I picked this up, but it's does specify a format in
your respond_to block:
Here's the do_request (and a sample spec) for one of my specs where
I'm checking for a generated csv file:
def do_request
@request.env["HTTP_ACCEPT"] = "text/csv"
get :show, :id => "1"
end
it "should return a csv download" do
@controller.should_receive(:send_file).with(@file, {:filename => "[EMAIL
PROTECTED]
}.csv", :type => 'text/csv', :disposition => 'attachment'})
do_get
end
Now my assumption is that your mime-type would need to be registered
in rails for this to work (if you have need of one outside of the
norm), which arguably has the added benefit of ensuring you added it
into your environment initializers...
