I am recently working through a Rails 5 upgrade, and am running into this error when I try to fire up the rails console:

/actionpack-5.0.0/lib/action_controller/test_case.rb:49:in initialize': wrong number of arguments (0 for 2) (ArgumentError)

Currently bundle update rails has finished with gem dependencies resolved enough to to do the update to 5.0.0, rspec is running (albeit with a lot of breaks I am fixing). I can also run rails s without an error.

Here is the line of code breaking:

https://github.com/rails/rails/blob/master/actionpack/lib/action_controller/test_case.rb

Full stack:

    Redundant question, solved here: http://stackoverflow.com/questions/38188968/ruby-on-rails-5-0-upgrade-not-working-with-rails-console-or-dbmigrate – Scott W Aug 02 '16 at 23:53

Kudos to Scott W.

Issue mostly answered here: Ruby on Rails 5.0 upgrade not working with rails console or db:migrate

I want to clarify that gem 'draper', github: 'drapergem/draper', branch: 'rails-5' no longer works, but gem 'draper', github: 'audionerd/draper', branch: 'rails5' did work to fix this error.
