Testing models with RSpec using devise

Question

I am using devise for authentication in my rails app and I'm unable to test any model with RSpec. Controller specs work fine, but I'm unable to make model specs work.

I am getting this error:

Failures:

1) Group should create new group

Failure/Error: Unable to find matching line from backtrace

I have included

  config.include Devise::TestHelpers

in my spec_helper.rb. Here is my model test file

require 'spec_helper'

describe Group do

  before :each do 
    @group = Factory.build(:group)
  end 

  it "should create new group" do
    Group.create!(@group)
  end
end

This is my factories.rb file

Factory.define :group do |group|
  group.name "Example group"
  group.description "Example description"
end

How to fix this?

Answer 1

config.include Devise::TestHelpers, :type => :controller
