Why is devise not displaying authentication errors on sign in page?

Question

I\'m using rails 4.2

I have a helper file called devise_helper.rb

module DeviseHelper
    def devise_error_messages!
        return \"\" if resource         


        

Answer 1

For newer version of Rails/Devise I recommend:

Instead of <%= devise_error_messages! %> do:

      <% if flash[:alert] %>
        <%= flash[:alert] %>
      <% end %>

Your test may look something like this (note, you must make this a 'feature' functional test to have access to the "page" variable):

RSpec.feature 'Sign In', :type => :feature do

  describe "correct error message w/ wrong password" do
    before :each do
      @user = create(:user)
      @user.confirm

      visit new_user_session_path
      fill_in "user_email", with: @user.email
      fill_in "user_password", with: "wrongpassword"
      click_button "Log in"
    end

    it "tells user on page 'Invalid Email or password'" do
      expect(page).to have_text("Invalid Email or password")
    end
  end

end
