Capybara can't find a file to attach in an RSpec/Rails test

I'm using Capybara/RSpec to write a feature test in a Rails 5 app to check the uploading of images on my site. I am getting this error:

  1) Photos user adds a photo
     Failure/Error: attach_file("photo[image]", '/app/assets/images/instagram-logo.jpg')


 Capybara::FileNotFound:
   cannot attach file, /app/assets/images/instagram-logo.jpg does not exist

My test is require 'rails_helper' require 'web_helpers'

RSpec.feature "Photos", type: :feature do
  scenario "user adds a photo", :type => :feature do
    add_photo
    page.should have_content("Instagram Logo")
    expect(page).to have_css("img[src*='instagram-logo.jpg']")
  end
end

Web helper:

def add_photo
  sign_up
  visit "/photos"
  click_button "New Photo"
  fill_in "Title", :with => "Instagram Logo"
  attach_file("photo[image]", Rails.root + '/app/assets/images/instagram-logo.jpg')
end

The view:

  <div class="field">
    <%= form.label :title %>
    <%= form.text_field :title, id: :photo_title %>
  </div>

  <div class="field">
    <%= form.label :image %>
    <%= form.file_field :image, id: :photo_title %>
  </div>

  <div class="actions">
    <%= form.submit %>
  </div>

The HTML compiled from the view:

<form enctype="multipart/form-data" action="/photos" accept-charset="UTF-8" method="post"><input name="utf8" type="hidden" value="&#x2713;" /><input type="hidden" name="authenticity_token" value="igZ4MndDfIQdZOmdiPxKu14bTIkAQTeKG+hwq0E6swKuskkkiCFwEVkarMgS26lc83z1eB/QyuQtnfFLRyuLWQ==" />

  <div class="field">
    <label for="photo_title">Title</label>
    <input id="photo_title" type="text" name="photo[title]" />
  </div>

  <div class="field">
    <label for="photo_image">Image</label>
    <input id="photo_title" type="file" name="photo[image]" />
  </div>

  <div class="actions">
    <input type="submit" name="commit" value="Create Photo" data-disable-with="Create Photo" />
  </div>
</form>

The file is definitely in that filepath. I have tried it without the Rails.root, and also originally had it in the public folder where I tried Rails.root + /public/instagram-logo.jp and simply /public/instagram-logo.jpg and finally instagram-logo.jp. Not sure if the issue is the filepath or perhaps a bit further back along the line. Have also tried attach_file("image"... in the web_helper.

Any help much appreciated!

When you pass an abolute path like Rails.root + '/app/assets/images/instagram-logo.jpg', Rails.root will be ignored. Try Rails.root + 'app/assets/images/instagram-logo.jpg' and see what happens.

Also check if the File really exists with: 

File.exist?(Rails.root + 'app/assets/images/instagram-logo.jpg')

(Since this is the error thrown by CapyBara https://github.com/teamcapybara/capybara/blob/3a2c5d21e756460d388995aa9698c4bc8c6ba49d/lib/capybara/node/actions.rb#L238)

FYI: This is a behaviour of Pathname:

pry(main)> Pathname.new("/this/is/my/root") + "/plus/absolute"
=> #<Pathname:/plus/absolute>
pry(main)> Pathname.new("/this/is/my/root") + "plus/relative"
=> #<Pathname:/this/is/my/root/plus/relative>
