Hi ,

I created trigger for lead conversion and i  am doing the lead conversion in class and its working properly but i am facing the issue with the Test code  coverage for classand my trigger had 100 % code coverage

Right now i am getting only 61% code coverage for my test class and please find the both trigger and class as well.

Trigger
------------:

trigger Leads on Lead (after update) {
    
    if(Trigger.isAfter && Trigger.isUpdate){
        Leads l = new Leads();
        l.SetContactRoleDefaults(Trigger.new, Trigger.oldMap);
    }

for this i had 100% code coverage

Class
======:


public class Leads {
    
// Sets default values on the Opportunity and Opportunity Contact Role record created during Conversion. Called on AFTER UPDATE
public void SetContactRoleDefaults(Lead[] leads, map<ID,Lead> old_leads)
{
    
    set<ID> set_opptyIDs = new set<ID>();
                
    // Get Opportunity IDs into a Set if the lead was just converted and an Opportunity was created
    for (Lead l:leads){
        if (l.IsConverted && !old_leads.get(l.id).IsConverted){
            if (l.ConvertedOpportunityId != null){
                set_opptyIDs.add(l.ConvertedOpportunityId);
            }
        }
    }
    
    // Update Opportunity Contact Roles
    list<OpportunityContactRole> list_opptyContactRolesToUpdate = new list<OpportunityContactRole>();
    for(OpportunityContactRole ocr:[select Id,IsPrimary,Role from OpportunityContactRole where OpportunityId in :set_opptyIDs]) {
        ocr.IsPrimary = true;
        ocr.Role = 'Decision Maker'; // set to what you want defaulted
        list_opptyContactRolesToUpdate.add(ocr);
    }
    
     System.debug('list_opptyContactRolesToUpdate size : '+list_opptyContactRolesToUpdate.size());
    
    if (list_opptyContactRolesToUpdate.size() > 0) {
    System.debug('list_opptyContactRolesToUpdate : '+list_opptyContactRolesToUpdate);
        delete list_opptyContactRolesToUpdate;
    }
    
}

}
Bold lines are not get covered

Test Class:
==========
@IsTest
private class Leads_Test {
    static testMethod void SetContactRoleDefaults_Test() {
           
            RecordType Rectype = [Select id from RecordType where name=:'Insurance Provider'];
            
            Account Acc = new Account();
            Acc.Name = 'Company';
            Acc.RecordTypeId = Rectype.Id;
            Insert Acc;
          
            Lead l = new Lead();
            l.lastname = 'Lastname';
            l.firstname = 'FirstName';
            l.company = 'Company';
            //l.Ready_to_Convert__c = true;
            insert l;
         
            System.debug('--------l Value---------'+l);
       
            User testUser1 = new User();
          
            //Convert the Lead
            test.startTest();
           
            Database.LeadConvert lc = new database.LeadConvert();          
            lc.setLeadId(l.id);
            lc.setDoNotCreateOpportunity(true);
            lc.setOwnerId(testUser1.id);
            lc.setConvertedStatus('Qualified');
           
            Database.LeadConvertResult lcr = Database.convertLead(lc);
            System.assert(lcr.isSuccess());
           
            Lead existingLead = [Select id, isConverted, ConvertedAccountId, ConvertedOpportunityId, createdbyid FROM Lead where id = :l.id];
           
            System.assert(existingLead.isConverted);
            System.assert(existingLead.ConvertedAccountId != null);
            System.assert(existingLead.ConvertedOpportunityId != null);
           
            test.stopTest();

}
}
Right now my code coverage is 61% can any help me  to reach the 100%
if any one help would be greatly appriciated .
