Test controller failed: NoMethodError: undefined method `env' for nil:NilClass - ruby-on-rails

Question

I have a problem with unit testing in ruby on rails (rails v. 5.001). The user needs to login in a test unit, but how can I implement this? Here is the code:
appointments_controller_test.rb
require 'test_helper'
class AppointmentsControllerTest < ActionDispatch::IntegrationTest
include Devise::TestHelpers
setup do
#heikoAppointment = appointments(:appointment_heiko)
#heiko = users(:heiko)
heiko = users(:heiko)
end
test "should get index" do
get appointments_url
assert_response :success
end
test "should get new" do
sign_in #heiko
get new_appointment_url
assert_response :success
end
......
appointments_controller.rb
class AppointmentsController < ApplicationController
load_and_authorize_resource
layout 'appointment', only: [:shopper_show, :senior_show]
def index
#shopping_lists = ShoppingList.where(user_id: current_user.id)
#users = User.senior.where.not(id: current_user.id).order(:firstname)
##appointments = Appointment.where(user_id: current_user.id)
##invitations = Invitation.where(user_id: current_user.id)
#todo: merge #invitations.appointmen into #appointments
end
# GET /shopping_processes/1
# GET /shopping_processes/1.json
def show
#appointment = Appointment.find(params[:id])
#shopping_lists = get_both_lists
#users = get_both_users
end
# POST /shopping_processes
# POST /shopping_processes.json
def create
#appointment.status = nil
#appointment.processed = nil
#appointment.user_id = current_user.id
sl_created = create_shopping_list?
respond_to do |format|
if #appointment.save
format.html { redirect_to #appointment, notice: t(:appointment_created) }
format.json { render :show, status: :created, location: #appointment }
else
if sl_created
ShoppingList.find(#appointment.shopping_list_id).destroy
end
format.html { render :new }
format.json { render json: #appointment.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /shopping_processes/1
# PATCH/PUT /shopping_processes/1.json
def update
respond_to do |format|
if #appointment.update(appointment_params)
format.html { redirect_to #appointment, notice: t(:appointment_updated) }
format.json { render :show, status: :ok, location: #appointment }
else
format.html { render :edit }
format.json { render json: #appointment.errors, status: :unprocessable_entity }
end
end
end
# DELETE /shopping_processes/1
# DELETE /shopping_processes/1.json
def destroy
#appointment.destroy
respond_to do |format|
format.html { redirect_to appointments_url, notice: t(:appointment_deleted) }
format.json { head :no_content }
end
end
def shopper_index
end
def ready_index
appointments_hash = {}
customers = User.where.not(current_appointment: nil).where(role: :senior)
customers.each {|user| appointments_hash[user.current_appointment.id] = user.current_appointment}
shoppers = User.where.not(current_appointment: nil).where(role: :shopper)
shoppers.each {|user| appointments_hash.delete(user.current_appointment.id)}
#appointments = []
appointments_hash.each { |appointment_id, appointment| #appointments.push(appointment)}
end
def shopper_show
#appointment = Appointment.find(params[:id])
#shopping_lists = get_both_lists
both_users = get_both_users
#users = {}
first = true
both_users.each do |user|
#users[user.id] = {color: (first ? 'blue' : 'yellow'), name: user.firstname + ' ' + user.lastname}
first = false
end
end
def senior_show
#appointment = Appointment.find(params[:id])
if #appointment.user == current_user
#shopping_list = #appointment.shopping_list
else
#shopping_list = #appointment.invitation.shopping_list
end
#D.S.:Diese zuweisung funktioniert nicht richtig. Sie wurde vor den DB änderung erstellt und muss angepasst werden
#D.S.:ShoppingItem.joins(:list_item) und ListItem.where(shopping_list_id: #shopping_list.id]) ergeben ein korrektes Resultat
#D.S.:Aber zusammengenommen ist die query leer
##shopping_items = ShoppingItem.joins(:list_item).where(list_item: [shopping_list_id: #shopping_list.id])
end
private def get_both_lists
shopping_lists = [ #appointment.shopping_list]
if #appointment.invitation && #appointment.invitation.shopping_list
shopping_lists << #appointment.invitation.shopping_list
end
shopping_lists
end
private def get_both_users
users = [ #appointment.user]
if #appointment.invitation
users.push(#appointment.invitation.user)
end
users
end
private
# Use callbacks to share common setup or constraints between actions.
def set_appointment
#appointment = Appointment.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def appointment_params
params.require(:appointment).permit(:shopper_id, :status, :appointed, :processed, :shopping_list_id, invitation_attributes: [:user_id, :message ])
end
def create_shopping_list?
if #appointment.shopping_list_id.blank?
name = "Liste für den " + #appointment.appointed.strftime("%d.%m.%Y").to_s
invitee_id = "" + (#appointment.invitation.user_id.to_s) if #appointment.invitation
name = name + ( " mit " + User.find(invitee_id).firstname) unless invitee_id.blank?
sl = current_user.shopping_lists.create(:name => name)
#appointment.shopping_list_id = sl.id
true
else
false
end
end
end
And here is the Error I get when I run the test:
Error:
AppointmentsControllerTest#test_should_get_new:
NoMethodError: undefined method `env' for nil:NilClass
Does somebody know the solution? I would be very thankful
UPDATE: include Devise::TestHelpers is deprecated. Now I use include Devise::Test::IntegrationHelpers. Now my appointments_controller_test.rb looks like this:
require 'test_helper'
class AppointmentsControllerTest < ActionDispatch::IntegrationTest
include Devise::Test::IntegrationHelpers
def sign_in(user)
post user_session_path \
"heiko#me.com" => user.email,
"hhdk#s0" => user.password
end
setup do
#heikoAppointment = appointments(:appointment_heiko)
#heiko = users(:user_heiko)
sign_in(#heiko)
end
test "should get index" do
get appointments_url
assert_response :success
end
test "should get new" do
sign_in(#heiko)
get new_appointment_url
assert_response :success
end
However I get another error:
AppointmentsControllerTest#test_should_get_new [C:/Users/Clemens/meindorfladen/Server/test/controllers/appointments_controller_test.rb:33]:
Expected response to be a <2XX: success>, but was a <302: Found> redirect to <http://www.example.com/users/sign_in>
Does somebody knows why there is this redirect to http://www.example.com/users/sign_in? I thought now the user is signed in

You should include Devise::Test::IntegrationHelpers not Devise::TestHelpers as per the readme.
