rspec / testing after_action

I guess am not testing it the right way, but still I was wondering how to make sure a method call is triggered in an after_action.

Having the followings :

  class AbcdController < ApplicationController
    after_action :handle_after, only: [:receive]
    def receive
       …… do some stuff
    end

    private

    def handle_after
       MyModule.my_method(some_data)
    end
  end

Then I'd like to test it like so (in a request spec) :

post  '/abcd/receive.json', params: params
expect(MyModule).to receive(:my_method)

This test does not passes. What would be an other approach to make sure the MyModule.method is called when the url if reached ?

Try have_received:

post  '/abcd/receive.json', params: params
expect(MyModule).to have_received(:my_method)

That's basically the way to do it.

Maybe, when you want more integration approach, instead of checking if MyModule received :my_method test the effect of calling this Module. For example, if it was recording an event in the DB, check 

expect {post '/abcd/receive.json'}.to change{ Event.count }.by(1)

You need to define borders when your testing stops, so you have to balance amount of mocking with deeply checking the behavior of your app.
