No guarantees here, but it''s possible that
ActionView::TestCase::TestController is not loaded yet, in which case its own
definition of default_url_options would clobber yours when it does get loaded.
Try this instead:

ActionView::TestCase::TestController.class_eval do
  undef_method :default_url_options
  def default_url_options(options={})
    { :locale => I18n.default_locale }
  end
end

ActionDispatch::Routing::RouteSet.class_eval do
  undef_method :default_url_options
  def default_url_options(options={})
    { :locale => I18n.default_locale }
  end
end

If those classes aren''t loaded yet, Rails will find and load them first
(via its autoload strategy) before invoking class_eval on them, thus ensuring
that you''re replacing the existing methods rather than writing methods
that will later be replaced.

HTH,
