stub any_instance using Minitest

Question

How can I do the following without using any_instance from Mocha? I just want to test a protected Controller as described here without using Rspec.

class PortfoliosControllerTest < ActionController::TestCase

  setup do
    @portfolio = portfolios(:p2)
    user = @portfolio.user

    token = Doorkeeper::AccessToken.create!(application_id: 'minitest',
                                            resource_owner_id: user.id)
    PortfoliosController.any_instance.stubs(:doorkeeper_token).returns(token)
  end
end

Have you seen this solution for stubbing with no libraries? http://stackoverflow.com/a/10329105/356060 — TuteC, Nov 10 '14 at 00:44

You don't need to stub any instance of PortfoliosController, just the instance that the test is using. This is available in the @controller variable, as explained in the ActionController::TestCase documentation.

class PortfoliosControllerTest < ActionController::TestCase

  setup do
    @portfolio = portfolios(:p2)
    user = @portfolio.user

    token = Doorkeeper::AccessToken.create!(application_id: 'minitest',
                                            resource_owner_id: user.id)
    @controller.stubs(:doorkeeper_token).returns(token)
  end
end

`NoMethodError: undefined method `stubs' for #` now I guess, I just need the correct way to stub with Minitest – André Ricardo Nov 01 '14 at 00:36
If you have required Mocha then `.stubs` will be available. That error makes me think you haven't loaded Mocha. – blowmage Nov 03 '14 at 15:21

not requiring Mocha is part of my question. How can I do it using only Minitest? – André Ricardo Nov 05 '14 at 18:42

since controller tests are integration tests in rails 5, this won't work anymore. #sadpanda – srecnig Jul 22 '16 at 13:02

I'd recommend checking out this gem. Would allow you to do something like...

class PortfoliosControllerTest < ActionController::TestCase
  def cool_test
    PortfoliosController.stub_any_instance(:doorkeeper_token, token) do
      # Assert whatever you were going to assert
    end
  end
end

kind of nice not to have to worry about setup either.

'no Mocha' version of 'blowmage' answer

 class PortfoliosControllerTest < ActionController::TestCase

  setup do
    @portfolio = portfolios(:p2)
    user = @portfolio.user

    token = Doorkeeper::AccessToken.create!(application_id: 'minitest',
                                            resource_owner_id: user.id)
    @controller.stub(:doorkeeper_token,token) do
      #do your tests
    end
  end
end
