Tips

If you want to have this file downloaded, like in your tests, you could use this following piece of code:

def image_file(size: '300x300', format: 'png', background_color: nil, text_color: nil, text: nil)
  file = Tempfile.new("faker_placeholdit")
  file.binmode
  file << Net::HTTP.get(URI(Faker::Placeholdit.image(size: size, format: format, background_color: background_color, text_color: text_color, text: text)))
  file.close

  ::File.new(file.path)
end
