rails test issue with devise

[modosc]

(this is a weird and probably rare occurrence so i'm just logging it for posterity)

i have a controller setup with devise and mounted like so in my routes:

devise_for :users, :controllers => { sessions: 'users' }

if i setup a functional test for this like so:

it 'works with a valid password' do
  # have to do this (or write an integration test) since devise does stuff
  # from inside of the router and blows up otherwise
  @request.env["devise.mapping"] = Devise.mappings[:user]
  post :create, user: { email: user.email, password: user.password }, access_token: access_token, format: :json
  expect(response).to have_http_status(:created)
end

it 'fails with an invalid password' do
  @request.env["devise.mapping"] = Devise.mappings[:user]
  post :create, user: { email: user.email, password: 'asdfasdfisdf8981u23123' }, access_token: access_token, format: :json
  expect(response).to have_http_status(:unauthorized)
end

the positive case passes, but on the failure case i get this nobrainer error:

 NoMethodError:
   undefined method `total_duration' for nil:NilClass

 # ./spec/controllers/users_controller_spec.rb:17:in `block (3 levels) in <top (required)>'

note that nobrainer isn't being used at all in this test.

writing the same test as an integration test works fine and doesn't result in the error, i expect it's got something to do with devise and the router but i don't have the time to dig too deep right now.

that should be fixed :)
