Question

rspec-rails (2.7.0) rails (3.0.10)
post: Rails 3.1 Error Catching is irrelevant for me.

Code:

class ApplicationController < ActionController::Base
  unless Rails.application.config.consider_all_requests_local
    rescue_from ActiveRecord::RecordNotFound, :with => :render_404
    rescue_from Exception, :with => :render_500
    rescue_from FunnyException, :with => :my_errors

    def my_errors(exception)
      #some stuff for production
      puts "=======From top====#{Rails.application.config.consider_all_requests_local}"
    end
  else
    rescue_from FunnyException, :with => :my_errors
    def my_errors(exception)
      #some stuff for development
      puts "=====From bottom======#{Rails.application.config.consider_all_requests_local}"
    end
  end
end

This code perfectly works with production/development… problem is when I wanna test it with rspec. How to switch test case between environments?

I tried adding something like:

before do
  Rails.application.config.consider_all_requests_local = true
end

I get:

…=====From bottom======true .=====From bottom======true .=====From
bottom======true .=====From bottom======true

so tried

before do
  Rails.application.config.consider_all_requests_local = false
end

so I get:

…=====From bottom======false .=====From bottom======false .=====From
bottom======false .=====From bottom======false

How is that even possible? … same with changing spec_helper

config.before(:each) do
  Rails.application.config.consider_all_requests_local = false
end

unless is not working. Top section is unreachable with rspec… always hits Bottom why ? I assume it is somehow tied now with Rack… but is there any solution to dynamically change this behavior inside rspec?

Answer 1

Ok I found quite easy solution

before do
  Rails.application.config.consider_all_requests_local = false
  load "application_controller.rb"
end

after do
  Rails.application.config.consider_all_requests_local = true
  load "application_controller.rb"
end

It is part of anonymous application controller test suite.

You have to add after block… because this change will persist through other suites.

Any improvements welcome 😀

edit: Using spork and guard causes for me sometimes random errors… before :all seems to solve that problem
