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: test_gem_resolver_dependency_request.rb
    path of file: ./repos/truffleruby/test/mri/tests/rubygems
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
require_
    
  def test_matches_spec_eh_prerelease
    spec = util_spec "a", "1.a"

    dependency = dep "a", ">= 0"
    dr = @DR.new dependency, nil

    assert dr.matches_spec? spec
  end
