Hi ,

I created a trigger on Lead object and some custom lookup fields to update after insert.
It works fine. I added test code and the code coverage is not covering all code.
Really appreciate of some one can help with what I missed. Here is my trigger and class.
FYI, my test code also includes convert lead whcih is extra.

***Trigger***
trigger UpdateLeadDistifields on Lead (after insert) {
    Set<ID> LeadId = new Set<Id>();
    for (Lead cLead : Trigger.New){
        
        Lead l = [select Id,OwnerId,PartnerAccountId,RecordTypeId from Lead where  Id = :cLead.Id];
        RecordType rt = [select Name FROM RecordType where Id = :l.RecordTypeId];
        
        
        if (rt.name == 'DealRegistration'){
            User u = [select Id ,AccountId from User where Id = :l.OwnerId and AccountId  != '' and ContactId != '' and IsPortalEnabled = true];
            Account a = [select Id, RecordTypeId from Account where Id = :u.AccountId ];
            RecordType accrt = [select Name FROM RecordType where Id = :a.RecordTypeId];
            l.PortalUser__c = u.Id;
        l.PortalAccount__c = u.AccountId;
        if (accrt.Name == 'Distributor'){
            l.DistiAccount__c = l.PartnerAccountId ;
            
            
        }
        
        }else {
            l.PortalUser__c = l.OwnerId;
            l.PortalAccount__c = l.PartnerAccountId;
        }
        update l;
    }
}
