include Devise::TestHelpers --- NoMethodError: undefined method `env' for nil:NilClass

I'm trying to use the devise test helpers while doing integration
tests but I'm getting this error once I include Devise::TestHelpers in
my integration test helper.

NoMethodError: undefined method `env' for nil:NilClass
/home/alex/.rvm/gems/ruby-1.9.2-p0/gems/activesupport-3.0.0/lib/active_support/whiny_nil.rb:48:in
`method_missing'
/home/alex/.rvm/gems/ruby-1.9.2-p0/bundler/gems/devise-5c928df/lib/devise/test_helpers.rb:55:in

/home/alex/.rvm/gems/ruby-1.9.2-p0/gems/activesupport-3.0.0/lib/active_support/testing/setup_and_teardown.rb:34:in
`run'

I'm using the git version of devise.

Am I missing some setup or is this a bug?

Ahh, nevermind, I see further down on the docs that I shouldn't use
these helpers in integration tests.
