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_integration_ssl_session.rb
    path of file: ./repos/puma/test
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require_relative 'helper'
require_relative 'helpers/integration'

# These tests are used to verify that Puma works with SSL sockets.  Only
# integration tests isolate the server from the test environment, so there
#
    
  def client_skt(tls_vers = nil, session_pems = [])
    ctx = OSSL::SSLContext.new
    ctx.verify_mode = OSSL::VERIFY_NONE
    ctx.session_cache_mode = OSSL::SSLContext::SESSION_CACHE_CLIENT
    if tls_vers
      if ctx.respond_to? :max_version=
        ctx.max_version = tls_vers
        ctx.min_version = tls_vers
      else
        ctx.ssl_version = tls_vers.to_s.sub('TLS', 'TLSv').to_sym
      end
