Rspec：水豚幫手找不到鏈接

Question

建立一個基本的博客應用程序，以推動我學習TDD，所以我是相當新的。我有問題讓水豚識別鏈接。好像所有的元素都在的地方，所以我在我缺少什麼困惑..

這裏是失敗的：

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)>' 

規格/支持/ 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 

規格/控制器/ posts_controller_spec.rb

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 
      sign_in(build_stubbed(:user)) 
      @post = Post.last 
      expect(@post.user).to eq(user) 
      end 
    end

如果這個信息是相關的;身份驗證是從頭構建的，我還沒有實施授權。

'註冊'是一個鏈接，而不是一個按鈕，因此您需要使用click_link（或click，它適用於這兩種類型）。
