In your test_helper.rb file's ActiveSupport::TestCase class, add a new method log_in_as like this:

require "test_helper"
ENV["RAILS_ENV"] = "test"
require File.expand_path("../../config/environment", __FILE__)
require "rails/test_help"
require "minitest/rails"
require "minitest/reporters"
Minitest::Reporters.use!(
    Minitest::Reporters::SpecReporter.new,
    ENV,
    Minitest.backtrace_filter
)

class ActiveSupport::TestCase
  fixtures :all
  include FactoryGirl::Syntax::Methods

  # Returns true if a test user is logged in.
  def is_logged_in?
    !session[:user_id].nil?
  end

  # Logs in a test user.
  def log_in_as(user, options = {})
    password    = options[:password]    || 'password'
    remember_me = options[:remember_me] || '1'
    if integration_test?
      post login_path, session: { email:       user.email,
                                  password:    password,
                                  remember_me: remember_me }
    else
      session[:user_id] = user.id
    end
  end

  private

  # Returns true inside an integration test.
  def integration_test?
    defined?(post_via_redirect)
  end
end

class ActionController::TestCase
  include Devise::TestHelpers
end

Then, use this log_in_as method instead of sign_in in your test:

require "test_helper"

class AwardedBidsControllerTest < ActionController::TestCase
  test "should get index" do
    user = create(:user)
    log_in_as user
    get :index
    assert_response :success
  end
end
