Problem with Rspec testing sign_in (Devise) with Request and rswag - ruby-on-rails

Question

I was tempted to use rswag with rspec to document REST API and write test at the same time.
I am trying to fallow tutorials and documentations but I cannot get sign_in endpoint working ( devise - session ).
When I do run rspec than I receive status code error.
require 'swagger_helper'
require 'rails_helper'
require 'shared_context'
describe 'Sonaaar REST API', type: :request do
...
path '/users/sign_in' do
post 'Sign In' do
tags 'Session'
consumes 'application/json'
produces 'application/json'
parameter name: :user, in: :body, schema: {
type: :object,
properties: {
email: { type: :string },
password: { type: :string },
},
required: ['email', 'password']
}
response '201', 'sign in', { 'HTTP_ACCEPT' => "application/json" } do
response '201', 'sign in', { 'HTTP_ACCEPT' => "application/json" } do
#
# let(:user) do
# create(:user, email: 'email#domain.com', password: 'Password1')
# end
#Error
# Failure/Error:
# raise UnexpectedResponse,
# "Expected response code '#{response.code}' to match '#{expected}'\n" \
# "Response body: #{response.body}"
#
# Rswag::Specs::UnexpectedResponse:
# Expected response code '401' to match '201'
# Response body: {"error":"You need to sign in or sign up before continuing."}
let(:user) { { user: { login: 'email#domain.com', password: 'Password1' } } }
# Rswag::Specs::UnexpectedResponse:
# Expected response code '401' to match '201'
# Response body: {"error":"You need to sign in or sign up before continuing."}
# /Users/filip/.rvm/gems/ruby-2.7.1/gems/rswag-specs-2.4.0/lib/rswag/specs/r
run_test!
end
Than i do have RSpec error:
1) Sonaaar REST API /users/sign_in post sign in returns a 201 response
Failure/Error:
raise UnexpectedResponse,
"Expected response code '#{response.code}' to match '#{expected}'\n" \
"Response body: #{response.body}"
Rswag::Specs::UnexpectedResponse:
Expected response code '401' to match '201'
Response body: {"error":"You need to sign in or sign up before continuing."}

Answer 1

Request specs need a little bit more help than just the normal warden helpers that work for feature specs:
RSpec.configure do |config|
config.include Warden::Test::Helpers
end
Add to rails_helper or another file and require in rails_helper:
module DeviseRequestSpecHelpers
include Warden::Test::Helpers
def sign_in(user)
login_as(user, scope: :user)
end
def sign_out
logout(:user)
end
end
Then in rails_helper add
RSpec.configure do |config|
config.include DeviseRequestSpecHelpers, type: :request
end
You should be able to login now in request specs with:
context 'some context' do
scenario 'some scenario' do
login_as(user)
end
end

Answer 2

as #sam said, but actually you can just include the warden helpers
RSpec.configure do |config|
config.include Warden::Test::Helpers
end
And then
let(:admin) { create(:admin) } # for this case it's devise :admins
before do
login_as(admin, scope: :admin)
end
# If you want to logout admin
after do
logout(:admin)
end
it 'should return 200 'do
get 'some_path_that_needs_session'
expect(response).to have_http_status(200)
end
You can refer to [Warden::Test::Helpers] (https://www.rubydoc.info/github/hassox/warden/Warden/Test/Helpers) docs
