RSpec with devise test helpers

Testing RSpec
1

I’ve set my Rails (engine) project to include devise and other tools
like FactoryGirl.
I’d like to write some tests with contexts around anon/authenticated
users.

In my spec_helper.rb’s RSpec.configure block, I have this:

config.include Devise::TestHelpers, type: :controller

Which gives me this, when running rspec:

  1. PropertiesController GET ‘index’ returns http success
    Failure/Error: Unable to find matching line from backtrace
    TypeError:
    no implicit conversion of nil into Hash

/Users/phendrick/.rvm/gems/[email protected]/gems/devise-3.0.0/lib/devise/test_helpers.rb:31:in
merge!' # /Users/phendrick/.rvm/gems/[email protected]/gems/devise-3.0.0/lib/devise/test_helpers.rb:31:inblock in warden’
#
/Users/phendrick/.rvm/gems/[email protected]/gems/warden-1.2.3/lib/warden/manager.rb:23:in
`initialize’
…

Without the TestHelpers module included, the specs run (obviously none
of them have devise logic in them just yet).

Any ideas what’s causing this error and how I can resolve it?

thanks.
