Rspec: how to execute ApplicationController method from feature spec

It's a simple (and maybe common) question but I can't find a clear answer.

I'm testing my rails engine from the dummy application with Rspec and Capybara. In my feature spec I need to use a ApplicationController method named get_component() with a specific argument. How can I do it?

My feature test is: 

require "rails_helper"

describe "My test", type: :feature do
    it "gets a component if slug is provided" do
        # ...
        component = ApplicationController.get_component( slug )
        # ...
    end
end

Which returns 

NoMethodError:
undefined method `get_component' for #<ApplicationController:0x007ff7207234f8>

I don't want to mock/stub that method, I want it to run for real.

Also, the application ApplicationController should inherit the engine one, shouldn't it? So it's right to call ApplicationController, isn't it?

Remember that get_component is an instance method, not a class method, so you can only call it on an ApplicationController object, not on the class itself. Try this instead...

component = ApplicationController.new.get_component( slug )
