Testing

Minitest

Here is an example of how you can test-drive your configuration using Minitest:

class SomeControllerTest < ActionController::TestCase

  test "index with token authentication via query params" do
    get :index, { user_email: "[email protected]", user_token: "1G8_s7P-V-4MGojaKD7a" }
    assert_response :success
  end

  test "index with token authentication via request headers" do
    @request.headers['X-User-Email'] = "[email protected]"
    @request.headers['X-User-Token'] = "1G8_s7P-V-4MGojaKD7a"

    get :index
    assert_response :success
  end
end

Rspec

Here is an example of how you can test-drive your configuration using Rspec:

require 'rails_helper'

RSpec.describe 'when user logs in', type: :request do

  describe "POST #create as :json" do

    let(:endpoint) { user_session_path }
    let(:headers) { {'Content-Type': 'application/json', 'Accept': 'application/json' } }
    let(:user) { create(:user) }
    let(:email) { user.email }
    let(:password) { user.password }
    let(:right_request) { { user: { email: email, password: password } } }
    let(:wrong_request) { { user: { email: email, password: 'wrong_password' } } }

    it "should successfully return access token" do
      post endpoint, JSON.dump(right_request), headers

      expect(response).to be_success

      json = JSON.parse(response.body)
      expect(json['authentication_token']).to_not be_empty
    end

    it "should return error message" do
      post endpoint, JSON.dump(wrong_request), headers

      expect(response).to have_http_status(401)

      json = JSON.parse(response.body)
      expect(json['error']).to eq I18n.t('devise.failure.invalid')
    end

  end

end
