Test Class for Trigger.

Hi,

This is my trigger and how to write test class for this trigger.

trigger OppProductDelete on OpportunityLineItem (before delete){
Id sysAdminId = [Select Id, Name from Profile where id = '00e90000001qXNbAAM' LIMIT 1].Id;
for (OpportunityLineItem oppProd : trigger.old){
if(UserInfo.getProfileId() ==sysAdminId)
oppProd.addError('This Opp Product may not be deleted');}
}

thanks.

Hi Srikanth,

1. Please do not hard code profile id to anywhere. User profile name instead of that.
2. To cover your trigger, you need to insert, opportunity, product, pricebook. Then finally delete it and assert the exception.

Find the modfied class and new test class, it will solve your problem.

Trigger 
trigger OppProductDelete on OpportunityLineItem (before delete)
{
Id sysAdminId = [Select Id, Name from Profile where Name = 'System Administrator' LIMIT 1].Id;
for (OpportunityLineItem oppProd : trigger.old)
{
if(UserInfo.getProfileId() ==sysAdminId)
oppProd.addError('This Opp Product may not be deleted');
}
}

Test Class
  
@isTest
private class TestLineItemDelete
{
    
    static testMethod void deleteLineItem()
    {
        Profile p = [SELECT Id FROM Profile WHERE Name='System Administrator'];

            oppLineItem.PricebookEntryId = customPriceBookEntry.Id;
            oppLineItem.UnitPrice = 7000;
            oppLineItem.Quantity = 5;
            insert oppLineItem;
            
            try

            }
            catch(DmlException e)
            {
                system.assert(e.getMessage().contains('This Opp Product may not be deleted'));
            }

Hi Sreekant, 

Have you tried any snippet of code that you can share?

You need to first insert an opportunity  and then opportunity line item in your test class and then delete it.

Hi Sreekanth,

Please use below code it will help you to solve your problem .
But only thing is that in each record level you have to give the mandatory fields as per your organisation .
  
@isTest(SeeAllData=true)
  private class TestOppProductDeleteOne {
   public static testMethod void unitTest() {
      Profile p = [SELECT Id FROM Profile WHERE Name='Standard User']; 
      User u = new User(Alias = 'standt', Email='standarduser@testorg.com', 
      EmailEncodingKey='UTF-8', LastName='Testing', LanguageLocaleKey='en_US', 
      LocaleSidKey='en_US', ProfileId = p.Id, 
      TimeZoneSidKey='America/Los_Angeles', UserName=Datetime.now().getTime() + 'test@xxx.com');

      System.runAs(u) {
        Account acc=new Account();
          acc.Name='TestAcc';
          insert acc;
         
      Product2 newProd = new Product2();
          newProd.Name = 'test product';
          newProd.family = 'test family';
          insert newProd;

     PriceBookEntry pbEntry = new PriceBookEntry();
        pbEntry.UnitPrice = 300;
        pbEntry.PriceBook2Id = [select id from PriceBook2 where isStandard = true].Id;
        pbEntry.Product2Id = newProd.Id;
        pbEntry.IsActive = true;
       insert pbEntry ;
     Opportunity opp=new Opportunity();
          opp.AccountId=acc.id;
          opp.Name='TestOpp';
          opp.closeDate=System.Today().addMonths(5);
          Opp.StageName='Prospecting';
          opp.Pricebook2Id=pbEntry.PriceBook2Id;
          insert opp;
    
    OpportunityLineItem oppLitem=new opportunitylineItem();
          oppLitem.pricebookentryid=pbEntry.Id; 
         oppLitem.Quantity=1; 
         oppLitem.OpportunityId=opp.id; 
         oppLitem.TotalPrice=1000;
         Insert oppLitem;
         delete oppLitem;
      }
   }
}
