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_parallel.rb
    path of file: ./repos/sshkit/test/unit/runners
    
    the code of the file until where you have to start completion: require "helper"
require "sshkit"

module SSHKit
  module 
    
      def test_wraps_ruby_standard_error_in_execute_error
        host = Host.new("deployer@example")
        runner = Parallel.new([host]) { raise "oh no!" }
        error = assert_raises(SSHKit::Runner::ExecuteError) do
          runner.execute
        end
        assert_match(/deployer@example/, error.message)
        assert_match(/oh no!/, error.message)
      end
