ruby on rails - Rspec test helper -

i having hard time figuring out how test helper because current_group not defined in test case , not sure how can stub it.

module admin   module employeeshelper     def upload_access       policy(current_group).can_bulk_create_employees?     end      def dashboard_params       download_employee_url = upload_access ?         download_admin_group_employees_import_csv_index_path(current_group) : nil       upload_employee_url = upload_access ?         admin_group_employees_import_csv_index_path(current_group) : nil       make_hash(upload_employee_url, download_employee_url)     end      private      def make_hash(upload_url, download_url)       {          employees: @employees,         addemployeeurl: new_admin_group_employee_path(current_group),         terminated_employees: @terminated_employees,         new_employees: @new_employees,         test_employees: @test_employees,         group_id: current_group.id,         downloademployeeurl: download_url,         uploademployeeurl: upload_url       }      end   end end 

here's test looks like, fails because current_group not defined.

require 'rails_helper'  describe admin::employeeshelper   let!(:group) { create(:group) }    before     # stub doesn't work because helper doesn't implement current_group      allow(helper).to receive(:current_group).and_return(group)   end    'returns correct dashboard props'     allow(helper).to receive(:upload_access).and_return(true)     props = helper.dashboard_params     expect(props).values_at(:downloademployeeurl, :uploademployeeurl).should_not include(nil)   end end 

if problem current_group method, include helper in dummy class. this:

let(:klass) {   class.new     include admin::employeeshelper      def current_group       nil     end   end }  let(:instance) { klass.new }  before    allow(instance).to receive(:current_group).and_return('whatever') # test-specific group end  'returns correct dashboard props'   allow(instance).to receive(:upload_access).and_return(true)   props = instance.dashboard_params   expect(props).values_at(:downloademployeeurl, :uploademployeeurl).should_not include(nil) end 

although foresee you'll have include url helpers too. , set instance vars. in all, isn't worth trouble.
