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: rspec.rb
    path of file: ./repos/vcr/lib/vcr/test_frameworks
    
    the code of the file until where you have to start completion: module VCR
  # Integrates VCR with RSpec.
  module RSpec
   
    
      def configure!
        ::RSpec.configure do |config|

          when_tagged_with_vcr = { :vcr => lambda { |v| !!v } }

          config.before(:each, when_tagged_with_vcr) do |ex|
            example = ex.respond_to?(:metadata) ? ex : ex.example

            cassette_name = nil
            options = example.metadata[:vcr]
            options = case options
                      when Hash #=> vcr: { cassette_name: 'foo' }
                        options.dup
                      when String #=> vcr: 'bar'
                        cassette_name = options.dup
                        {}
                      else #=> :vcr or vcr: true
                        {}
                      end

            cassette_name ||= options.delete(:cassette_name) ||
                              VCR::RSpec::Metadata.vcr_cassette_name_for(example.metadata)
            VCR.insert_cassette(cassette_name, options)
          end

          config.after(:each, when_tagged_with_vcr) do |ex|
            example = ex.respond_to?(:metadata) ? ex : ex.example
            VCR.eject_cassette(:skip_no_unused_interactions_assertion => !!example.exception)
          end
