Hi All,
I have written a small trigger on opportunity.Which is updating field 'opportunity sales Leader' with the user in opportunity team member.Here is trigger.

trigger UpdateOpportunity on Opportunity (after insert) 
{
    Set<Id> setOfOppty = new Set<Id>();
    List<Opportunity> listOfOpptyToUpdate = new List<Opportunity>();
    for(Opportunity opp : Trigger.New){
        if(opp != null && (opp.RecordTypeId == Label.Oppty_Record_Type_ISV || opp.RecordTypeId == Label.Oppty_Record_Type_OEM || opp.RecordTypeId == Label.Oppty_Record_Type_Wholesale || opp.RecordTypeId == Label.Oppty_Record_Type_xSP)){
            setOfOppty.add(opp.Id);
        }
    }
    List<OpportunityTeamMember> listOTM = new List<OpportunityTeamMember>([SELECT Id, UserId, OpportunityId, User.Name FROM OpportunityTeamMember WHERE OpportunityId in :setOfOppty AND TeamMemberRole = :Label.Opportunity_Sales_Leader]);
    for(OpportunityTeamMember otmObj: listOTM){
        
        if(otmObj != null && otmObj.UserId!=null && otmObj.OpportunityId != null){
            Opportunity opp = new Opportunity(Id = otmObj.OpportunityId, Opportunity_Team_Member_Sales_Leader__c = otmObj.UserId);
            listOfOpptyToUpdate.add(opp);
        }
    }   
    if(!listOfOpptyToUpdate.IsEmpty()){
        Database.SaveResult[] saveResultList = Database.update(listOfOpptyToUpdate,false);
        for(Database.SaveResult svResult : saveResultList){
            if(!svResult.isSuccess()){                
                system.debug('Error::'+svResult);
                break;
            }
        }
    }
}

And Here Is Test clas.;

@Istest(SeeAllData=false)
Private class Test_opportunity 
{
     public static testmethod void testOpportunity()
     {   
         //ProId = [SELECT Id FROM Profile WHERE Name = 'Consumer Sales Ops'].Id;
         User user = new User();
        
        user.FirstName = 'Test';
        user.LastName = 'Name';
        user.CompanyName = 'IT Test Company';
        user.MobilePhone = '123-456-7890';
        
        user.Username = 'testUser-' + '@test.com';
        user.Email = 'testUser-' +'@test.com';
  user.Alias = 'test';
        user.CommunityNickname = 'test1';
        user.TimeZoneSidKey = 'America/New_York';
        user.LocaleSidKey = 'en_US';
        user.EmailEncodingKey = 'UTF-8';
        user.ProfileId = '00e1I000000Veel';
        user.LanguageLocaleKey = 'en_US';
        
        user.Street = '123 Test St';
        user.City = 'Testcity';
        user.State = 'va';
        user.PostalCode = '23223';
        user.Country = 'USA';
        
        insert user;
         Date myDate = Date.today();
         Opportunity opp=new opportunity();
         opp.RecordTypeId='0122F0000004ot9';
         opp.name='test opp';
         opp.AccountId='0012F00000EXcyQ';
         opp.CurrencyIsoCode='AED';
         opp.CloseDate= myDate;
         opp.StageName='Identification';
         opp.Opportunity_Team_Member_Sales_Leader__c=user.Id;
         insert opp;
         OpportunityTeamMember opptyteam=new OpportunityTeamMember();
         opptyteam.opportunityId=opp.Id;
         opptyteam.TeamMemberRole='Sales Leader';
         opptyteam.UserId=user.Id;
         insert opptyteam;
         opp.Opportunity_Team_Member_Sales_Leader__c = opptyteam.UserId;
         update opp;
         
     }
}

But its covering only 53 %

if(otmObj != null && otmObj.UserId!=null && otmObj.OpportunityId != null){
            Opportunity opp = new Opportunity(Id = otmObj.OpportunityId, Opportunity_Team_Member_Sales_Leader__c = otmObj.UserId);
            listOfOpptyToUpdate.add(opp);
        }

this if condition and also error statment is not been covered.any suggestion on this would be really help full
