Rspec doesn't see my model Class. uninitialized constant error

Question

I\'m writing tests on Rspec for my models in Ruby on Rails application. And I receive this error while starting \'rspec spec\'

command:
/spec/models/client_spec         


        

Answer 1

I'm using Rails 5.0.0.1.
Here's how I resolved this concern.

On your Gemfile, please add -> gem 'rspec-rails', ">= 2.0.0.beta"

Like so,

group :development, :test do
  gem 'rspec-rails', ">= 2.0.0.beta"
end

Reason: if the rspec-rails is not added and when you execute the rspec command, it will generate this error -> "cannot load such file -- rails_helper"

Now, execute this command on the terminal.

bundle install

Once bundle command went good, execute the rails generate. Like so,

rails generate rspec:install

Reason: this command will create a new .rspec(hit overwrite when prompted), spec/rails_helper.rb and spec/spec_helper.rb

Now, at this point, rspec should pretty much run properly.
However, if you encounter an error where in the model is not found e.g. cannot load such file -- idea, try adding this on top of your spec/spec_helper.rb

require 'rubygems'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)

Reason: seems that spec_helper is not loading the Rails environment. We're requiring it.

Hope this helps!
