I recently included GZIP in my Rails 4 application after this Thoughtbot blog post , and I also added the use Rack::Deflaterfile suggested by this post to my config.ru . My Rails seems to be serving compressed content, but when I test it with RSpec, the test fails because it response.headers['Content-Encoding']is zero.
Here is my .rb application:
module MyApp
class Application < Rails::Application
config.middleware.use Rack::Deflater
end
end
Here is my specification:
require 'rails_helper'
describe GeneralController, type: :controller, focus: true do
it "a visitor has a browser that supports compression" do
['deflate', 'gzip', 'deflate,gzip', 'gzip,deflate'].each do |compression_method|
get 'about', {}, {'HTTP_ACCEPT_ENCODING' => compression_method }
binding.pry
expect(response.headers['Content-Encoding']).to be
end
end
it "a visitor browser does not support compression" do
get 'about'
expect(response.headers['Content-Encoding']).to_not be
end
end
When I run curl --head -H "Accept-Encoding: gzip" http://localhost:3000/, I get the following output:

When I load the site and look at the Inspector’s Network tab, I see that the response size is smaller than before, but my test still does not work. I'm not sure if I skipped a step here with my test or if there is a problem with my implementation Rack::Deflater.
