Capybara not finding link in support file.

Question

I'm following along this course as a guide while developing my own app. I'm currently trying to add the spec/support/authentication_helpers.rb helper file.

In the video, Jason uses stubs to stub out a current_user and user_id. From my understanding, you are no longer able to stub in a before block, so I'm having my helper file manually sign_in using Capybara.

Basically, I'm copying the sign_in process from the spec/features/users/registration_spec.rb file. That Capybara spec (with the same syntax) passes with no issues, however, my authentication_helpers.rb fails..

 1) PostsController#GET create with valid attributes creates a post by the current_user
     Failure/Error: sign_in(build_stubbed(:user))
     Capybara::ElementNotFound:
       Unable to find link "Sign Up"
     # ./spec/support/authentication_helpers.rb:7:in `sign_in'
     # ./spec/controllers/posts_controller_spec.rb:44:in `block (4 levels) in <top (required)>'

spec/support/authentication_helper.rb

require 'rails_helper'

module AuthenticationHelpers

    def sign_in(x)
        visit root_path
        click_link "Sign Up"
        fill_in "First Name", with: x.first_name
        fill_in "Last Name", with: x.last_name
        fill_in "Email", with: x.email
        fill_in "Password", with: x.password
        fill_in "Password Confirmation", with: x.password
        click_button "Sign Up"
    end
end

spec/controllers/posts_controller_spec.rb

  before :all do
    sign_in(build_stubbed(:user))
  end

describe '#GET create' do
    context 'with valid attributes' do
      before :each do
        post :create, post: attributes_for(:post)
      end

          it { expect(Post.count).to eq(1) }
          it { expect(flash[:success]).to eq('Your post has been saved!') }
          it { expect(assigns(:post)).to be_a(Post) }
          it { expect(assigns(:post)).to be_persisted }
          it { expect(response).to redirect_to Post.first }

          it "creates a post by the current_user" do
            @post = Post.last
            expect(@post.user).to eq(user)
          end
    end

Try changing this:

<a href="#"><%= link_to "Sign Up", new_user_path %></a>

to this:

<%= link_to "Sign Up", new_user_path %>

The link_to helper generates its own a tag, so putting a link inside a link may confuse Capybara. Same for the Log In link.
