My final solution for this was to write...
describe Cart do
before(:each) do
@product1 = mock_model Product, :name => "Brown Trousers", :price =>
23.99
@product2 = mock_model Product, :name => "Yellow Shirt", :price =>
15.74
@cart_item1 = mock_model CartItem, :name => "Brown Trousers", :price
=> 23.99, :quantity => 1
@cart = Cart.new
end
it "should increment quantity when it does find a product" do
@cart_item1.should_receive(:increment_quantity).once.with(:no_args).and_return(2)
@cart.should_receive(:find_item_by_name).twice.with("Brown
Trousers").and_return(nil, @cart_item1)
@cart.add_product(@product1)
@cart.add_product(@product1)
@cart.items.should have(1).item
end
end
Which seems to work. I'm right?
