You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: integration_spec.rb
    path of file: ./repos/dd-trace-rb/spec/datadog
    
    the code of the file until where you have to start completion: require 'datadog/tracing'
require 'datadog/statsd'

RSpec.describe 'Datadog integration' do
  context 'graceful shutdown', :integration do
    before do
      # TODO: This test is flaky, and the flakiness affects JRuby really often.

    
      def open_file_descriptors
        # Unix-specific way to get the current process' open file descriptors and the files (if any) they correspond to
        Dir['/dev/fd/*'].each_with_object({}) do |fd, hash|
          hash[fd] =
            begin
              File.realpath(fd)
            rescue SystemCallError # This can fail due to... reasons, and we only want it for debugging so let's ignore
              nil
            end
        end
