Hi Malli,

Below is the Test Class:
  
@isTest
public class testforcontact {
	@istest
    static void testme(){
        account a1=new account(name='aaa',phone='9908294936');
		insert a1;
		contact c1=new contact(lastname='suresh', firstname='malli',accountid=a1.id);
		insert c1;    
        Account acc = [Select Id, count_of_contact__c from Account where ID =: a1.Id LIMIT 1];
		System.assertEquals(1, acc.count_of_contact__c);
        delete c1;
		Account acc = [Select Id, count_of_contact__c from Account where ID =: a1.Id LIMIT 1];
		System.assertEquals(0, acc.count_of_contact__c);
    }
}

Please do let me know if it helps you.

Hi Malli,

Below is the code which is used for real roll up summary calculation:
  
trigger PrimaryContactCount on Contact (after insert, after delete, after undelete,after update) {
    set<Id> accIds = new set<Id>();
    
    if(trigger.isinsert || trigger.isUpdate || trigger.Isundelete){
        for(Contact con: Trigger.new){
			if(Trigger.isInsert || Trigger.isUndelete || (con.AccountId != Trigger.oldMap.get(con.Id).AccountId))
				accIds.add(con.AccountId);
        }
    }
    
    if(trigger.isUpdate || trigger.isDelete) {
        for(Contact con: Trigger.old){
            if(Trigger.isDelete || (con.AccountId != Trigger.oldMap.get(con.Id).AccountId))
				accIds.add(con.AccountId);
        }
    }    
    
	if(!accIds.isEmpty()) {
		List<Account> accList = [select id, Count_of_Contact__c, (Select Id from Contacts) from Account Where ID IN: accIds];
		
		for(Account acc : accList){
			system.debug('Contacts--->'+acc.contacts.size());
			acc.Count_of_Contact__c = acc.contacts.size();
		}
		update accList;
	}
}

Please do let me know if it helps you.
