Stubbing current_user in Rails functional test using Minitest

Question

I'm having some trouble stubbing current_user in a Rails functional test for a controller. I'm using Rails 4 and Minitest. Currently, in the setup block I have this line.

ApplicationController.any_instance.stubs(:current_user).returns(users(:admin))

That's kind of working; however, I'm getting the following error from my view where current_user is referenced into a routing/url helper (edit_user_path(current_user)).

ActionView::Template::Error: No route matches {:action=>"edit", :controller=>"users", :id=>nil} missing required keys: [:id]

What is the recommended way of stubbing current_user in controller/functional test? Here's my full test.

require 'test_helper'

class Admin::SitesControllerTest < ActionController::TestCase
  setup do
    @site = sites(:test)
    @request.env['HTTP_HOST'] = "#{@site.ssl_prefix}.testing.com"
    ApplicationController.any_instance.stubs(:current_user).returns(users(:admin))
  end

  test "should show edit form" do
    get :edit, id: @site.id
    assert_response :success
    assert_template layout: "layouts/admin/layout"
  end
end

Have you implemented `current_user` yourself, or it it part of the library? — D-side, Oct 21 '15 at 19:57
i hope http://stackoverflow.com/questions/22187127/test-helper-method-with-minitest answers your question — chanakya devraj, Oct 21 '15 at 20:30
D-side, current_user is a method I have defined myself (not using devise) in a helper (Admin::SessionHelper). — ajporterfield, Oct 22 '15 at 02:38
Thanks for this! A way to stub it in RSpec 3: `allow_any_instance_of(ApplicationController).to receive(:current_user).and_return(my_user)` — Henrik N, Jun 16 '16 at 12:41

As always there are many ways to do this. The recommended way to stub the controller instance is to stub directly on the instance you are dealing with.

def setup
  @controller.stubs(:current_user).returns(users(:admin))
end

In controller tests you have access to the @controller instance.

Hope this helps.

`def setup puts @controller end` prints `NilClass` – Chris Vilches Sep 06 '17 at 10:52
Are you using `ActionController::TestCase` ? FYI: https://github.com/rails/rails/blob/master/actionpack/lib/action_controller/test_case.rb#L264 – pixeltom Sep 07 '17 at 07:10
