need help - test class

Hi all,

I need help on test class, this is my class:

When creating a task of type (Phone Call or Last Face to Face) from contact,need to update the account fields

I have a trigger:
trigger TaskTrigger on Task (after delete, after insert, after undelete, after update, before delete, before insert, before update) {
    
    TaskTriggerHandler handler = new TaskTriggerHandler (Trigger.isExecuting, Trigger.size);
    //After Update
     if(Trigger.isUpdate && Trigger.isAfter){
         handler.OnAfterUpdate(Trigger.new,Trigger.oldMap);
          
   }
 }

TriggerHandler class:

public with sharing class TaskTriggerHandler {
    
    private boolean trigger_isExecuting = false;
    private integer batchSize = 0;
    
    public TaskTriggerHandler ( boolean isExecuting, integer size){
        trigger_isExecuting = isExecuting;
        batchSize = size;        
    }

    public void OnAfterUpdate(List<Task> Tklist, Map<id,Task> OldMaplst){
        //EXECUTE AFTER UPDATE LOGIC
        //first condition is to check the record type then 
         Set<ID> tid = new Set<ID>();
         list<Account> acclst = new list<Account>();
        
        for(Task tk:Tklist){
        if(tk.Whoid!=null && tk.WhoId.getSObjectType().getDescribe().getName()=='Contact'){
         tid.add(tk.whoid);
            }
          }
        List<Contact> con = new List<Contact>();
        con=[select id,accountid from Contact where id =:tid];
        Map<id,account>Lstacc=new Map<id,account>();
        if(!con.isEmpty()){
            account acc;
            for(Task tk:[select id,LastModifiedBy.name,type,LastModifiedDate from task where id in :Tklist]){
                DateTime dt = tk.LastModifiedDate;
                Date myDate = date.newinstance(dt.year(), dt.month(), dt.day());
                acc=new account(id=con[0].accountid);
                    if(tk.type=='Face 2 Face Meeting'){
                        acc.Last_Face_to_Face_Activity__c= myDate;
                        acc.Last_Visited_By__c =tk.LastModifiedBy.name;
                        
                    }
                    else if(tk.type=='Phone Call'){
                     acc.Last_Call_Activity__c =  myDate;
                    }
                     Lstacc.put(acc.id,acc);
        }
                if(!Lstacc.isEmpty())
                    Update Lstacc.values();

    }
  }
}

Change yout test class as below 
 
@isTest
public class TaskTriggerHandlerTest

static testMethod void testStandardUserwithTask()

Hi AviKerari,

You may want to put try....catch in your code

For test class/method, one of option is 
- create a input file with multiple records of task and upload to static resource.
- insert record from static resource and it will fire your trigger and execute other apex class
- create another input fiel with account details and upload to static resource
- compare the list from 3rd step and query for records of account and decide fail/success.

Give it a try and intimate if you were able to progress....

Thanks for the reply Britto, Please can you give an example of code that will be a great help

System.DmlException: Insert failed. First exception on row 0; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, TaskTrigger: execution of AfterUpdate

caused by: System.DmlException: Update failed. First exception on row 0; first error: MISSING_ARGUMENT, Id not specified in an update call: []

Looks like you have't added id while updating the records . ISSING_ARGUMENT, Id not specified in an update call
 

please check in code 
AviKesariAviKesari
I'm updating the account fields, so you mean account IDs in the triggerhandler class?
Raj VakatiRaj Vakati
yes .. here from this link   account acc

 
account acc;
            for(Task tk:[select id,LastModifiedBy.name,type,LastModifiedDate from task where id in :Tklist]){
                DateTime dt = tk.LastModifiedDate;
                Date myDate = date.newinstance(dt.year(), dt.month(), dt.day());
                acc=new account(id=con[0].accountid);
                    if(tk.type=='Face 2 Face Meeting'){
acc.Id = 'YOUR ACCOUNID' ;
                        acc.Last_Face_to_Face_Activity__c= myDate;
                        acc.Last_Visited_By__c =tk.LastModifiedBy.name;
                        
                    }
                    else if(tk.type=='Phone Call'){
                     acc.Last_Call_Activity__c =  myDate;
                    }
                     Lstacc.put(acc.id,acc);
        }
                if(!Lstacc.isEmpty())
                    Update Lstacc.values();

    }

 
AviKesariAviKesari
account acc;
            for(Task tk:[select id,LastModifiedBy.name,type,LastModifiedDate from task where id in :Tklist]){
                DateTime dt = tk.LastModifiedDate;
                Date myDate = date.newinstance(dt.year(), dt.month(), dt.day());
               // acc=new account(id=con[0].accountid);
                    if(tk.type=='Face 2 Face Meeting'){
                     acc.Id = con[0].accountid; //updated HERE

        }
                if(!Lstacc.isEmpty())
                    Update Lstacc.values();

    }

But I'm getting a different error:

no luck, I have updated the test class, still the same null reference error.
AviKesariAviKesari
I have updated the code to :
whatid is account id and whoid is contact id..is this causing an issue? 


  List<Task> tasks = new List<Task>{};
            for(Integer i = 0; i < 5; i++) 
        {
            Task t = new Task(Subject='Donni'+i,Status='New',Priority='Normal',Type='Face 2 Face Meeting' ,whatid = a.Id, Whoid = c.Id );
            tasks.add(t);
        }
AviKesariAviKesari
update of account in the end helped to fix the issue. Thanks raj!
