I've already added my app a support button for microposts and if the user supports the micropost the button changes to "Not Support". Everything is working perfect in localhost but when I run "bundle exec rake test", I have an error.
Error
$ bundle exec rake test
1) Error:

You do hot have authenticated user in tests by default, so current_user
return nil
. Same error may happen in production, if user somehow visits that page without logging-in before.
If you are using devise for auth - see devise wiki on test helper
class SomeControllerTest < ActionController::TestCase
include Devise::TestHelpers
def setup
@request.env["devise.mapping"] = Devise.mappings[:user]
sign_in FactoryGirl.create(:user) # or other method of making/getting test user
end
