ruby on rails - RSpec tests broken after application i18n -

after finishing railstutorial.org have decided i18n application , suddently tests started failing following,

failures:

1) user pages index failure/error: sign_in user capybara::elementnotfound: unable find field "email" # ./spec/support/utilities.rb:5:in sign_in' # ./spec/requests/user_pages_spec.rb:11:inblock (3 levels)

the changes have made where,

routes.rb

sampleapp::application.routes.draw   scope '(:locale)'     resources :users     resources :sessions, only: [:new, :create, :destroy]     root to: 'static_pages#home'     match '/signup',    to: 'users#new',              via: 'get'     match '/signin',    to: 'sessions#new',           via: 'get'     match '/signout',   to: 'sessions#destroy',       via: 'delete'     match '/help',      to: 'static_pages#help',      via: 'get'     match '/about',     to: 'static_pages#about',     via: 'get'     match '/contact',   to: 'static_pages#contact',   via: 'get'   end 

and config/initializers/i18n.rb

i18n.default_locale = :en  languages = [   ['english',               'en'],   ['portuguese',        'pt'] ] 

before i18n routes looked following,

users_path      /users(.:format)    users#index     post    /users(.:format)    users#create new_user_path       /users/new(.:format)    users#new edit_user_path      /users/:id/edit(.:format)   users#edit user_path       /users/:id(.:format)    users#show     patch   /users/:id(.:format)    users#update     put     /users/:id(.:format)    users#update     delete  /users/:id(.:format)    users#destroy sessions_path   post    /sessions(.:format)     sessions#create new_session_path        /sessions/new(.:format)     sessions#new session_path    delete  /sessions/:id(.:format)     sessions#destroy root_path       /   static_pages#home signup_path         /signup(.:format)   users#new signin_path         /signin(.:format)   sessions#new signout_path    delete  /signout(.:format)  sessions#destroy help_path       /help(.:format)     static_pages#help about_path      /about(.:format)    static_pages#about contact_path        /contact(.:format)  static_pages#contact  

and now,

users_path      (/:locale)/users(.:format)  users#index     post    (/:locale)/users(.:format)  users#create new_user_path       (/:locale)/users/new(.:format)  users#new edit_user_path      (/:locale)/users/:id/edit(.:format)     users#edit user_path       (/:locale)/users/:id(.:format)  users#show     patch   (/:locale)/users/:id(.:format)  users#update     put     (/:locale)/users/:id(.:format)  users#update     delete  (/:locale)/users/:id(.:format)  users#destroy sessions_path   post    (/:locale)/sessions(.:format)   sessions#create new_session_path        (/:locale)/sessions/new(.:format)   sessions#new session_path    delete  (/:locale)/sessions/:id(.:format)   sessions#destroy root_path       /(:locale)(.:format)    static_pages#home signup_path         (/:locale)/signup(.:format)     users#new signin_path         (/:locale)/signin(.:format)     sessions#new signout_path    delete  (/:locale)/signout(.:format)    sessions#destroy help_path       (/:locale)/help(.:format)   static_pages#help about_path      (/:locale)/about(.:format)  static_pages#about contact_path        (/:locale)/contact(.:format)    static_pages#contact

could please provide tips beginners? support.

if you're going scope routes include locale, you'll need pass in locale paths when test them (as can see in new output rake routes, :locale expected), put, say, visit users_path, put
visit users_path(locale). locale list of i18n.available_locales. you'll need change strings you're using find fields i18n equivalent eg
fill_in "email" becomes fill_in i18n.t('sessions.new.email')

i i18n-ized sample app, here's user_pages_spec.rb give idea on kind of changes you'll need make.
