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: backhaulTests.m
    path of file: ./repos/monster/backhaul/tests
    
    the code of the file until where you have to start completion: classdef backhaulTests < matlab.unittest.TestCase
  
  properties
    Config;
    Logger;
    Simulation;
  end
  
  metho
    
function testDelay(testCase)
      %Apply backhaul
      testCase.Simulation = Monster(testCase.Config, testCase.Logger);
      %First arrival is expected to be after 1ms
      testCase.verifyTrue(testCase.Simulation.Traffic.TrafficSourceWithBackhaul(1,1)>10^(-3));
      %Last arrival time is expected to be larger than the number of
      %round in ms
      testCase.verifyTrue(testCase.Simulation.Traffic.TrafficSourceWithBackhaul(end
