Obtention d'une erreur constante non initialisée avec RSpec. Je ne sais pas quelle est la cause

Question

J'utilise RSpec pour tester et quand je suis parti travailler vendredi après-midi, mes tests passaient. Mais quand je suis allé à la maison et synchronisé mon dépôt, les tests ont échoué sur mon ordinateur portable. Maintenant au travail, les tests échouent encore. Ne croyez pas que c'est mon code car lancer rspec lui-même renvoie une erreur et le démarrage ne démarre même pas. Lorsque je tente de démarrer Spork, je reçois le message d'erreur suivant:

Using RSpec 
Loading Spork.prefork block...

Quelqu'un sait ce qui pourrait être la cause?

Answer 1

J'ai rencontré ce problème. Dans le spec_helper.rb essayez de remplacer:

require "rails" 

avec

require "rails/all" 

A travaillé dans ma situation.

Answer 2

Si ce n'est pas une application Rails et que vous ne voulez pas inclure tous Rails, ajouter ceci à votre spec_helper.rb:

require 'action_view' 

Answer 3

Vous devez initialiser l'environnement, ajoutez cette ligne à spec_helper.rb :

require File.expand_path("../../config/environment", __FILE__) 

Answer 4

vous pouvez rencontrer ce problème si vous essayez d'utiliser rspec-rails dans un projet non-rails. Dans ce cas, l'utilisation require "rails/all" n'est pas une option, car elle avait besoin des choses ActiveRecord vous laissant avec:

ActiveRecord::ConnectionNotEstablished: No connection pool with 'primary' found.

Au lieu de cela, vous pouvez résoudre ce problème avec:

require "action_controller/railtie"
