Hello there,

I'm still pretty new to code development and I am using the following trigger and class.

Trigger:

trigger AccountTerritoryTag on Account (before insert, before update)
{
    Set<String> setName =  new Set<String>();
    for (Account account : Trigger.new)
    {       
        if (account.RunAssignment__c == TRUE)
        {
            setName.add(account.RoutingKey__c);
        }   
    }   
    
    if(setName.size() > 0 )
    {
        List<RoutingKey__c> routingkey = [select Name,Territory__c from RoutingKey__c  where Name in :setName ];
        Map<String, RoutingKey__c> mapNameWiseR = new  Map<String, RoutingKey__c> ();
        for(RoutingKey__c  RK : routingkey )
        {
            mapNameWiseR.put(RK.Name , RK);
        }

        for (Account account : Trigger.new)
        {    
          if (account.RunAssignment__c == TRUE)
          {
              if (mapNameWiseR.containsKey(account.RoutingKey__c) )
              {   
                    RoutingKey__c rk = mapNameWiseR.get(account.RoutingKey__c);
                  //assign the territory 
                    account.Territory__c = rk.Territory__c;
                    account.RunAssignment__c = FALSE;
             
              }
           }
        }
        
    }
        
}

Test Class:

@isTest

private class AccountTerritoryTest
{
    static testMethod void AccountTerritoryTest()
    { 
       Territory__c t = new Territory__c();
       t.Name = 'TerritoryTest';
       insert t;
       
       RoutingKey__c k = new RoutingKey__c();
       k.Name = 'NAM|SMB|FL';
       k.Territory__c = t.id;
       insert k;
       
       Account a = new Account();
       a.Name  = 'Test';
       a.OverrideCountry__c = 'US';
       a.OverrideEmployees__c = 'A) 1-100';
       a.OverrideState__c = 'FL';
       a.RunAssignment__c = TRUE;
       insert a;
       
       a.RunAssignment__c  =  FALSE;
       a.Territory__c = t.id;
       update a;
       
    }
    
}

I'm stuck at 72% coverage and would like to increase as much as possible. I looked at my dev console and lines 17, 18, and 27-30 are uncovered by my class. I'm not certain how to write the class to cover these lines and the account update doesn't cover it. Can someone help/explain what I can do to fix this? Thank you in advance for the help!
