bypass_rescue
の使用
rescue_from
ステートメントで宣言されているカスタムのエラー処理だけでなく、Railsのデフォルトのエラー処理を回避するために bypass_rescue
を使用します。
これにより、例外が上流でどのように扱われているかにかかわらず、発生している例外の詳細を指定できます。
Background
Given a file named "spec/controllers/gadgets_controller_spec_context.rb" with:
class AccessDenied < StandardError; end
class ApplicationController < ActionController::Base
rescue_from AccessDenied, :with => :access_denied
private
def access_denied
redirect_to "/401.html"
end
end
Standard exception handling using rescue_from
Given a file named "spec/controllers/gadgets_controller_spec.rb" with:
require "rails_helper"
require 'controllers/gadgets_controller_spec_context'
RSpec.describe GadgetsController, type: :controller do
before do
def controller.index
raise AccessDenied
end
end
describe "index" do
it "redirects to the /401.html page" do
get :index
expect(response).to redirect_to("/401.html")
end
end
end
When I run rspec spec/controllers/gadgets_controller_spec.rb
Then the examples should all pass.
