RSpec Failure/Error: click_link article.title - ruby-on-rails

Question

I am facing this error when running an rspec test. I have tried click_link "Title 1" and assigning Article.create to a variable but the same error appears.
Failure/Error: click_link article.title
Capybara::ElementNotFound:
Unable to find link "Title 1"
comment_spec.rb
require "rails_helper"
describe 'navigate' do
let(:user) { FactoryGirl.create(:user) }
let(:article) do
Article.create(title: "Title 1", description: "Some description", user_id: user.id)
end
before do
login_as(user, :scope => :user)
end
describe 'create' do
before do
visit articles_path
end
it"permits a signed in user to write a review" do
click_link article.title
fill_in "Content", with: "An awesome article"
click_button "Post"
expect(page).to have_content("An awesome article")
expect(current_path).to eq(article_path(article.id))
end
end
end
spec/factories/user.rb
FactoryGirl.define do
sequence :email do |n|
"test#{n}#example.com"
end
factory :user do
name 'Tester'
email { generate :email }
password "asdfasdf"
password_confirmation "asdfasdf"
end
EDIT:
article/index.html.erb
<div class="tab-pane active" id="tab1">
<% #articles.each do |article| %>
<%= render 'article', article: article %>
<% end %>
</div>
_article.html.erb
<%= link_to article.title, article_path(article) %>

Answer 1

let is lazy loading which means that the block is not evaluated until you call it.
before do
article # calls the block
visit articles_path
end
An alternative is to use let! which is not lazy loading:
require "rails_helper"
describe 'navigate' do
let(:user) { FactoryGirl.create(:user) }
let!(:article) do
Article.create(title: "Title 1", description: "Some description", user_id: user.id)
end
before do
login_as(user, :scope => :user)
end
describe 'create' do
before do
visit articles_path
end
it"permits a signed in user to write a review" do
click_link article.title
fill_in "Content", with: "An awesome article"
click_button "Post"
expect(page).to have_content("An awesome article")
expect(current_path).to eq(article_path(article.id))
end
end
end
