Acceptance test failed when js enabled

I am having a weird problem with my acceptance test for login page.

The login works fine when js in not enabled ie. the following case:

  scenario "login with valid authentication" do
    visit login_path
    page.should have_content("Sprout Login开发者_运维技巧")
    fill_in("user_login", :with => "mark")
    fill_in("user_password", :with => "secured")
    click_button "Sign in"
    page.should have_content("mark")
  end

But when I enabled javascript, the login fails and gives invalid login message.

  scenario "login with valid authentication", :js => true do
    visit login_path
    page.should have_content("Sprout Login")
    fill_in("user_login", :with => "mark")
    fill_in("user_password", :with => "secured")
    click_button "Sign in"
    page.should have_content("mark")
  end

BTW I am using Devise for authentication. Thanks in Advance.

UPDATE: recently noticed that when js is enabled, test server is not starting and hence login fails. Any idea?

Your tests will fail unless a default user is created and logs in before each test runs. Devise provides test helpers to make it simple to create and log in a default user. Create a file spec/support/devise.rb:

RSpec.configure do |config|
  config.include Devise::TestHelpers, :type => :controller
end

I was having the same issue and found a thread with a solution:

RSpec.configure do |config|
  config.use_transactional_fixtures = false

  config.before(:suite) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end

end

For the DatabaseCleaner stuff to work you'll need to include the database_cleaner gem. If you haven't used it before, you may need to rake db:test:prepare before rerunning your tests. I hope this works for you, too!
