Team, 

I have the following trigger on my person accounts and am trying to run the below test class with the following error. 
Error: " System.ListException: List index out of bounds: 0 "  Saying its in line 3570 of my test class (which doesn't exsit)

Appreciate any guidance.

Trigger:

trigger LogPersonAccountChange on Account (before delete, after insert, after undelete)
{
  List<pi__ObjectChangeLog__c> logs = new List<pi__ObjectChangeLog__c>(); 

  if (Trigger.new != null) {
    for (Account account : Trigger.new) {

      if (Account.PersonEmail != null && Account.PersonEmail != '') {
        pi__ObjectChangeLog__c log = new pi__ObjectChangeLog__c();
        log.pi__ObjectFid__c = Account.PersonContactId;
        log.pi__ObjectType__c = 1;
        log.pi__ObjectEmail__c = Account.PersonEmail;

        if  (System.Trigger.isInsert) {
          log.pi__ObjectState__c = 1;
        } else if  (System.Trigger.isDelete) {
          log.pi__ObjectState__c = 2;
        } else if  (System.Trigger.isUnDelete) {
          log.pi__ObjectState__c = 3;

        }
        logs.add(log);
      }
    }
  } else if (Trigger.old != null) {
    for (Account account : Trigger.old) {
      if (Account.PersonEmail != null && Account.PersonEmail != '') {
        pi__ObjectChangeLog__c log = new pi__ObjectChangeLog__c();

        log.pi__ObjectFid__c = Account.PersonContactId

        ;
        log.pi__ObjectType__c = 1;
        log.pi__ObjectEmail__c = Account.PersonEmail;
        if  (System.Trigger.isInsert) {
          log.pi__ObjectState__c = 1;
        } else if  (System.Trigger.isDelete) {
          log.pi__ObjectState__c = 2;
        } else if  (System.Trigger.isUnDelete) {
          log.pi__ObjectState__c = 3;
        }
        logs.add(log);
      }
    }
  }

  if (logs.size() > 0) {

    insert logs;
  }
}

Test class: 
 

/**
 * This class contains unit tests for validating the behavior of Apex classes
 * and triggers.
 *
 * Unit tests are class methods that verify whether a particular piece
 * of code is working properly. Unit test methods take no arguments,
 * commit no data to the database, and are flagged with the testMethod
 * keyword in the method definition.
 *
 * All test methods in an organization are executed whenever Apex code is deployed
 * to a production organization to confirm correctness, ensure code
 * coverage, and prevent regressions. All Apex classes are
 * required to have at least 75% code coverage in order to be deployed
 * to a production organization. In addition, all triggers must have some code coverage.
 * 
 * The @isTest class annotation indicates this class only contains test
 * methods. Classes defined with the @isTest annotation do not count against
 * the organization size limit for all Apex scripts.
 *
 * See the Apex Language Reference for more information about Testing and Code Coverage.
