How to set locale in default url options for integration tests

Question

Using Rails 4.0.0beta1, i'm trying to create some integration tests. All my URLs are scoped with me locale (eg /en/user/new ) and i'm having the following error each time i try to call new_user_url :

ActionController::UrlGenerationError: No route matches {:action=>"new", :controller=>"user"} missing required keys: [:locale]

I've tried the solution given by @Balint Erdi in the following question

class ActionController::Integration::Session
  def url_for_with_default_locale(options)
    options = { locale: I18n.locale }.merge(options)
    url_for_without_default_locale(options)
  end

  alias_method_chain :url_for, :default_locale
end

It works but gives me a deprecation warning because of rails4:

DEPRECATION WARNING: ActionController::Integration is deprecated and will be removed, use ActionDispatch::Integration instead. (called from <top (required)> at /path/to/project/test/test_helper.rb:46)
DEPRECATION WARNING: ActionController::IntegrationTest is deprecated and will be removed, use ActionDispatch::IntegrationTest instead. (called from <top (required)> at /path/to/project/test/test_helper.rb:46)

For my controller tests i added this :

class ActionController::TestCase

  module Behavior
    def process_with_default_locale(action, http_method = 'GET', parameters = nil, session = nil, flash = nil)
      parameters = { locale: I18n.locale }.merge( parameters || {} ) 
      process_without_default_locale(action, http_method, parameters, session, flash)
    end

    alias_method_chain :process, :default_locale
  end 
end

I've also tested adding a default_url_options method directly into the tests but it did not work.

How can i set the default url parameters in integration tests ?

Answer 1

An option that worked for me (at least in Rails 4.2.0) was to add a setup method to the ActionDispatch::IntegrationTest class in my test/test_helper.rb :

class ActionDispatch::IntegrationTest
  def setup
    self.default_url_options = { locale: I18n.default_locale }
  end
end

Ok, it seems it's as easy as replacing ActionController by ActionDispatch . I don't know why it didn't work before but since I updated to the latest rails which deprecates rake test:integration for rails test integration it seems to work:

class ActionDispatch::Integration::Session
  def url_for_with_default_locale(options)
    options = { locale: I18n.locale }.merge(options)
    url_for_without_default_locale(options)
  end

  alias_method_chain :url_for, :default_locale
end

Rails 5, Minitest example:

class SomeTest < ActionDispatch::IntegrationTest
  setup do
    self.default_url_options = { locale: I18n.default_locale }
  end

  def test_something
    ...
  end
end
