Testing Object Instantiation in Rails Controllers

(In RSpec) I am testing that an object in my controller is getting instantiated:

CONTROLLER:

stripe_params = StripeParams.new(params)

TEST:

it "creates a new params instance" do
  get :message, params
  StripeParams.should_receive(:new).with(params)
end

... However, this is giving me the following test error:

expected: 1 time
received: 0 times

Solution

  • you have to work expectation prior to run the code:

    it "creates a new params instance" do
  StripeParams.should_receive(:new).with(params) 
  get :message, params
end
