hi,

I'm trying to create a test class for a trigger:

trigger deleteTask on OpportunityLineItem (before delete) {

List<OpportunityLineItem> OppLIs = Trigger.old;
List<Task> tasks = new List<Task>();

for (OpportunityLineItem OppLI : OppLIs) {

Opportunity Opp = [ Select OwnerId from Opportunity where id=:OppLI.OpportunityId limit 1 ];
User usuario = [ Select Sociedad__c from User where id=:Opp.OwnerId ];

//el usuario debe pertenecer a argentina = usuario.Sociedad__c == 1000
if ( usuario.Sociedad__c == '1000' ) {
tasks = [ Select Id from Task where whatID=:OppLI.OpportunityId and Subject='Recordatorio: Vencimiento de producto'];
}
}

delete tasks;

}

My test class is:

@isTest
private class deleteTaskTest {

static testMethod void myUnitTest() {

//Create a custom pricebook
Pricebook2 pb = new Pricebook2(Name='Custom Pricebok',IsActive=true);
insert pb;

// Create a new product
Product2 prod = new Product2(IsActive=true, Name='Product');
insert prod;

// Create a pricebook entry for custom pricebook
PricebookEntry pbe2 = new PricebookEntry(Pricebook2Id=pb.Id, Product2Id=prod.Id,
IsActive=true, CurrencyIsoCode='ARS', UnitPrice=100,

  UseStandardPrice=false);

insert pbe2;

test.startTest();

delete prod;

test.stopTest();

}
}

When I run this test class, I get this error message:

 Insert failed. First exception on row 0; first error: STANDARD_PRICE_NOT_DEFINED, No standard price defined for this product: []

In the line: insert pbe2;

 Can someone understand why this is happening? Thanks!
