Stubbing A Model Attribute
I am writing rspec test for my Cars class, and have a question regarding setting up mocks. I'd like to stub the parts array in Cars, how can i do that?
I have the following code:
class Cars
has_many :parts
def heavy_count
parts.inject(0) { |sum, v开发者_开发技巧| v.weight > 10 ? sum + 1 : sum }
end
end
With test
context ("#heavy_count") do
let(:car) {mock_model(Car, :brand => "toyota")}
let(:vote_1) {mock_model(Part, :weight => 11)}
let(:vote_2) {mock_model(Part, :weight => 11)}
it "should return 2 if there are 2 parts heavier than 10" do
#how do I stub parts here?
end
end
Assuming you're using RSpec for mocking and not another framework:
Part.should_receive(:find).and_return([vote_1, vote2])
