[HELP solved] undefiend method 'mutual_friendship' - Adding State > Destroying Friendships

I followed the video 'Destroying Friendships' (up to 3:10) I got error when trying to pass the test (context "#delete_mutual_friendship!" do) But I don't know what I am doing wrong, please help me.

1) Error:

test: #delete_mutual_friendship! should delete the mutual friendship. (UserFriendshipTest):
NoMethodError: undefined method `mutual_friendship' for nil:NilClass
    test/unit/user_friendship_test.rb:117:in `block (2 levels) in <class:UserFriendshipTest>'
    /usr/local/rvm/gems/ruby-1.9.3-p194/gems/shoulda-context-     1.0.2/lib/shoulda/context/context.rb:398:in `call'
    /usr/local/rvm/gems/ruby-1.9.3-p194/gems/shoulda-context- 1.0.2/lib/shoulda/context/context.rb:398:in `block in create_test_from_should_hash'
    /usr/local/rvm/gems/ruby-1.9.3-p194/gems/mocha-   0.10.5/lib/mocha/integration/mini_test/version_230_to_262.rb:28:in `run'

My code (user_friendship_test.rb):

  context "#delete_mutual_friendship!" do
    setup do
      UserFriendship.request users(:john), users(:jim)
      friendship1 = users(:john).user_friendships.where(friend_id: users(:jim).id).first
      friendship2 = users(:jim).user_friendships.where(friend_id: users(:john).id).first
    end

    should "delete the mutual friendship" do
      assert_equal @friendship2, @friendship1.mutual_friendship
      @friendship1.delete_mutual_friendship!
      assert !UserFriendship.exists?(@friendship2.id)
    end
  end

(user_friendship.rb)

    def delete_mutual_friendship!
        mutual_friendship.delete
    end

My entire code for this: https://github.com/yhagio/pwitter/blob/master/test/unit/user_friendship_test.rb https://github.com/yhagio/pwitter/blob/master/app/models/user_friendship.rb

Try putting @ signs in front of your friendship variables:

@friendship1 =
@friendship2 =

That will give you access to the variables in the later tests.
