How to write a View test in Rails with RSpec

I want to write a View test. What should I do?

Step 1. Learn the view template

<% content_for :head do %>
  <title>Project Name</title>

  <link
    rel="preload"
    as="image"
    href="<%= vite_asset_url 'images/logo.jpg' %>"
  />
<% end %>

<% @blogs.each_with_index do |blog| %>
  <li><%= blog.title %></li>
<% end %>

Here I see

1. View variable @blogs
2. Rails helper vite_asset_url

Step 2. How to stub a rails helper?

To do that I'm going to use the following way. Here in view I stub vite_asset_url and it will return a string "vite_asset_url".

allow(view).to
  receive(:vite_asset_url).and_return("vite_asset_url")

Step 3. How to stub a view variable?

To do that I use assign test helper.

assign(:blogs, [blog1, blog2, blog2])

Step 4. How a test should look?

It looks like that:

require 'rails_helper'

RSpec.describe "site/landing/index", type: :view do
  let!(:published_blogs) do
    create_list(:blog, 3, :published, :for_blog) do |blog, index|
      blog.title =  "Blog Title #{index.next}"
      blog.save!
    end
  end

  before do
    allow(view).to
      receive(:vite_asset_url).and_return("vite_asset_url")
  end

  it "renders attributes in show page" do
    assign(:blogs,  published_blogs)

    render

    expect(rendered).to match(/Blog Title 1/)
    expect(rendered).to match(/Blog Title 2/)
    expect(rendered).to match(/Blog Title 3/)
  end
end

That is it!
Happy Coding!
