Hi Gayatri Depending on the exact update and the relation to the first object, you could use Process Builder or Flows, or a combination of both. And if you want to simply display data in a child, you could use a formula field. Regards Andrew

Hi Gayatri Sorry for stealing your thread, but hopefully you have found this educational. @apuroop Ok, here is a quick example of why we grab the written record in our Apex Test Classes Simple Before Insert Trigger: trigger Lead_Testing on Lead (before insert){ if (Trigger.isBefore) { for (Lead lead : Trigger.new) { if (String.isEmpty(lead.Industry)) { lead.Industry = 'Other'; } } } } And a test class @isTest private class Lead_Testing_Test { @isTest static void test_method_one() { // Implement test code Lead beforeLead = new Lead(LastName='Sample', FirstName ='A', Company='ACME', Status = 'Open - Not Contacted', Email = 'sample@acme.acme'); System.assertEquals(null,beforeLead.Id); insert beforeLead; System.assertNotEquals(null,beforeLead.Id); System.assertEquals(null,beforeLead.Name); System.assertEquals(null,beforeLead.Industry); List insertedLeads = new List (); insertedLeads = [SELECT Id, Name, Industry FROM Lead WHERE Id = :beforeLead.Id]; Lead insertedLead = insertedLeads[0]; System.assertNotEquals(null,insertedLead.Id); System.assertEquals('A Sample',insertedLead.Name); System.assertEquals('Other',insertedLead.Industry); } @isTest static void test_method_two() { // Implement test code Lead beforeLead = new Lead(LastName='Sample', FirstName ='A', Company='ACME', Status = 'Open - Not Contacted', Email = 'sample@acme.acme', Industry = ''); insert beforeLead; System.assertEquals('',beforeLead.Industry); List insertedLeads = new List (); insertedLeads = [SELECT Id, Name, Industry FROM Lead WHERE Id = :beforeLead.Id]; Lead insertedLead = insertedLeads[0]; System.assertEquals('Other',insertedLead.Industry); } } Test one: So, we notice that in the first test the Industry value is null when we assert against 'in memory' value. But when we grab the written record, the asserted value is Other . (as set by the trigger). Note that I also have an assert before we insert the newLead record, to show that the record Id has not been created before we do the insert. Now, test two: To check that the issue is not because I didn't declare the field in the record creation, when we set the value to '' (blank) that is what is asserted in the in memory record. System.assertEquals('',beforeLead.Industry); This is because it is "in memory". But when we grab the written record, the asserted value is Other . (as set by the trigger). I included the Name field, as out of the box, the Name field is a concatenation of the FirstName and LastName fields. So even for OoB SF functions, the 'in memory' record is not updated by the insert, but we see that the Id is available to the in memory record after the insert. Regards Andrew

Hi I m new to sales force development ,I wrote Apex trigger for cross objects and finally trigger working ,now I should move to production ,I tried to write test class ,code coverage was zero ,Kindly help me

Trigger code

trigger Ag_PurchaseContract_UpdateTradeConfirmation_Trigger on Ag_Purchase_Contract__c (after insert,after update) {

set<string> tradeConfirmationNumSet = new set<String>();

string purchaseContractName = null;

for (Ag_Purchase_Contract__c purchase : Trigger.new)

{

list<Ag_Purchase_Contract__c> purlist = [select id, Trade_Confirmation_No__c,name from Ag_Purchase_Contract__c where Trade_Confirmation_No__c = :purchase.Trade_Confirmation_No__c and name != :purchase.name];

if (purlist != null && purlist.size() > 0 && purchase.Trade_Confirmation_No__c != null)

{

purchase.adderror('The TradeNumber is used in a different Purchase contract. The purchase contract number is ' + purlist[0].name );

}

else

{

purchaseContractName = purchase.name;

if(purchase.Trade_Confirmation_No__c != null )

{

if (purchase.Trade_Confirmation_No__c == Trigger.NewMap.get(purchase.Id).Trade_Confirmation_No__c)

{

tradeConfirmationNumSet.add(Trigger.NewMap.get(purchase.Id).Trade_Confirmation_No__c);

}

List<Trade_Confirmation__c> tcList = [Select ID,purchase_contract__c,name from Trade_Confirmation__c where id IN :tradeConfirmationNumSet];

for (Trade_Confirmation__c tc: TClist)

{

tc.purchase_contract__c = purchaseContractName;

}

update tcList;

}

the above trigger is working and

test class is

@isTest

private class Test_Ag_PurchaseContract {

@istest static void testSuccess(){

set<string> tradeConfirmationNumSet = new set<String>();

string purchaseContractName = 'AGP/19/03/16599';

String tradeConfirmationnum = 'AGC0000012';

Ag_Purchase_Contract__c purchase = new Ag_Purchase_Contract__c();

list<Ag_Purchase_Contract__c> purlist = [select id, Trade_Confirmation_No__c,name from Ag_Purchase_Contract__c where Trade_Confirmation_No__c = :tradeConfirmationnum and name=:purchaseContractName limit 1];

if (purlist != null && purlist.size() > 0)

{

purchase.adderror('The TradeNumber is used in a different Purchase contract. The purchase contract number is ' + purlist[0].name );

}

else

{

if(purchase.Trade_Confirmation_No__c != null )

{

tradeConfirmationNumSet.add(tradeConfirmationnum);

}

List<Trade_Confirmation__c> tcList = [Select ID,purchase_contract__c,name from Trade_Confirmation__c where id IN :tradeConfirmationNumSet limit 1];

system.debug('purchaseContractName '+ purchase.name);

system.debug('purchaseContractName After assign '+ purchaseContractName);

system.debug('TClist :'+tcList.size());

if(TClist!=null && TClist.size()>0)

{

for (Trade_Confirmation__c tc: TClist)

{

tc.purchase_contract__c = purchaseContractName;

system.debug('tc.purchase_contract__c '+ tc.purchase_contract__c);

}

try

{

update tcList;

}

catch(Exception e)

{

system.assertEquals(e.getMessage(), e.getMessage()) ;

}

With this test class Code coverage is zero.how to write pls help me ,

Hi Gayatri
Depending on the exact update and the relation to the first object, you could use Process Builder or Flows, or a combination of both. And if you want to simply display data in a child, you could use a formula field.
