ruby on rails - rspec controller testing with devise -

i'm using devise + rspec + factory + shoulda , having trouble controller specs. i've read bunch of articles , docs couldn't figure out best way log_in user , use user instance.

task nested under user index route /users/:user_id/tasks , task belongs_to :assigner, class_name: "user" , belongs_to :executor, class_name: "user"

at moment following code both tests fail. best approach sign_in user , use in controller tests?

the error message first one:

failure/error: expect(assigns(:tasks)).to eq([assigned_task, executed_task])  expected: [#<task id: 1, assigner_id: 1, executor_id: 2, .....>, #<task id: 2, assigner_id: 3, executor_id: 1, ......>]         got: nil  (compared using ==) 

the error second one:

failure/error: { is_expected.to respond_with :ok }    expected response 200, 302 

tasks_controller_spec.rb

require "rails_helper"  describe taskscontroller    describe "when user signed in"      describe "collections"        login_user       let(:assigned_task) { create(:task, assigner: @user) }       let(:executed_task) { create(:task, executor: @user) }       let(:other_task) { create(:task) }        context "get index"         before           :index, user_id: @user.id         end          "assigns user's tasks"           expect(assigns(:tasks)).to eq([assigned_task, executed_task])         end          { is_expected.to respond_with :ok }        end        context "get incoming_tasks"     end   end  end 

controller_macros.rb

module controllermacros   def login_user     before(:each)       @request.env["devise.mapping"] = devise.mappings[:user]       @user = create(:user)       sign_in @user     end   end end 

tasks controller

def index   @tasks = task.alltasks(current_user).uncompleted.includes(:executor, :assigner).order("deadline desc").paginate(page: params[:page], per_page: task.pagination_per_page) end 

add following line in rails_helper.

config.include controllermacros, :type => :controller  

see thread.

i assuming fails in rspec. when test in browser works fine.
