How to send custom header with rack::test?

I spent about two days without success trying to send custom headers with Rack::Test. I just can't send any header into my app. I found a lot of examples in the net with the similar code -- method( address, body, headers ), but for me they don't work at all.

ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]

# grep rack  Gemfile.lock
    rack (2.0.4)
    rack-protection (2.0.1)
      rack
    rack-test (1.0.0)
      rack (>= 1.0, < 3)
      rack-protection (>= 1.5.0)
      rack (~> 2.0)
      rack-protection (= 2.0.1)
  rack-test

The code in app (sinatra):

$log = Logger.new STDERR
class MyApi < Sinatra::Application
  before do
    $log.debug{ "Headers: #{ headers.keys.inspect }" }
  end
  get '/offers' do
    #... some code
  end
  post '/offers' do
    # .. some another code
  end
end

spec/api_spec.rb

RSpec.describe MyApi, '/offers' do
  include Rack::Test::Methods
  def app
    MyApi
  end

  context 'авторизация' do
    it 'правильная - get с токеном' do
      get '/offers', nil, {
        'X-Auth' => 'some key'
      }
      $log.debug{ "ENV was: '#{ last_request.env.keys }'" }
    end
    it 'правильная - post с токеном' do
      post '/offers', '', {
        'Content-Type' => 'application/json; charset: utf-8',
        'X-Auth' => 'some long key'
      }
    end
  end
end

Output contains for both tests:

Headers: ["Content-Type"]
...
ENV was: '["rack.version", "rack.input", "rack.errors",
"rack.multithread", "rack.multiprocess", "rack.run_once", 
"REQUEST_METHOD", "SERVER_NAME", "SERVER_PORT", "QUERY_STRING", 
"PATH_INFO", "rack.url_scheme", "HTTPS", "SCRIPT_NAME", "CONTENT_LENGTH", 
"rack.test", "REMOTE_ADDR", "X-Auth", "HTTP_HOST", "HTTP_COOKIE", 
"sinatra.commonlogger", "rack.logger", "rack.request.query_string", 
"rack.request.query_hash"]'

This code is working:

get '/offers', nil, { 'X-Auth' => 'long key' }

And this also is correct:

header 'X-Auth', 'some key'
get '/offers'

I changed the manner I look for that header in app:

request.get_header('HTTP_X_AUTH') || request.env['X-Auth']

The first - get_header was triggered when I call my app with curl, the last - request.env - when in tests.

You have to use Rack::Test::Methods#header (which delegates to Rack::Test::Session#header): 

it 'правильная - get с токеном' do
  header 'X-Auth', 'some key'
  get '/offers'
  $log.debug{ "ENV was: '#{ last_request.env.keys }'" }
end
