I can't seem to get my test code to check a chunk of my trigger.  I have a trigger, a class to prevent recursion, and my test class.

Trigger (basically any time the Opp Stage changes a pair or records are created in a custom object assigning points to the move to and from the stage.)  Lines 15 through 30 are not covered by the test class listed at the bottom.

 line 	 source
 1 	  trigger UpdateSalesScoreEvents on Opportunity (After update) {
 2 	  
 3 	   try {
 4 	  
 5 	   // List of variables to be used later.
 6 	   List<Sales_Score__c> ScoreEvents = new list<Sales_Score__c>();
 7 	   List<Opportunity> OldStage = New list<Opportunity>();
 8 	  
 9 	  
 10 	   // Add to the list all opps associated with an agreement in the trigger that has been signed
 11 	   for (Opportunity Opp: Trigger.New) {
 12 	   if ((Opp.Company_Division__c == 'Textura') && (Opp.StageName != trigger.oldMap.get(Opp.id).StageName) && (!ScoreEventHelper.hasAlreadyCreatedScores())){
 13 	  
 14 	   //
 15 	   Sales_Score__c OldEvent = new Sales_Score__c();
 16 	   OldEvent.Opportunity__c = opp.id;
 17 	   OldEvent.Direction__c = 'Leaving Stage';
 18 	   OldEvent.Movement_Date__c = system.Today();
 19 	   OldEvent.Stage__c = Trigger.oldMap.get(opp.ID).StageName;
 20 	   // Add to ScoreEvent list
 21 	   ScoreEvents.add(OldEvent);
 22 	  
 23 	   //
 24 	   Sales_Score__c Event = new Sales_Score__c();
 25 	   Event.Opportunity__c = opp.id;
 26 	   Event.Direction__c = 'Entering Stage';
 27 	   Event.Movement_Date__c = system.Today();
 28 	   Event.Stage__c = opp.StageName;
 29 	   // Add to ScoreEvent list
 30 	   ScoreEvents.add(Event);
 31 	  
 32 	  
 33 	   }
 34 	   ScoreEventHelper.setAlreadyCreatedScores();
 35 	   insert ScoreEvents;
 36 	   }
 37 	   } catch (Exception e) {Trigger.new[0].addError(e.getMessage());}
 38 	  }

 Class used to prevent recurrsion;

 1 	  public class ScoreEventHelper{
 2 	  
 3 	   // Static variables are local to the context of a Web request
 4 	  
 5 	   // (or testMethod during a runTests call)
 6 	  
 7 	   // Therefore, this variable will be initialized as false
 8 	  
 9 	   // at the beginning of each Web request which accesses it.
 10 	  
 11 	  
 12 	   private static boolean alreadyCreatedScores = false;
 13 	  
 14 	  
 15 	   public static boolean hasAlreadyCreatedScores() {
 16 	   return alreadyCreatedScores;
 17 	   }
 18 	  
 19 	   // By setting the variable to true, it maintains this
 20 	  
 21 	   // new value throughout the duration of the request
 22 	  
 23 	   // (or testMethod)
 24 	  
 25 	   public static void setAlreadyCreatedScores() {
 26 	   alreadyCreatedScores = true;
 27 	   }
 28 	  }

 This is the test method I created.  Something in it needs to be added to check more code from the trigger.

 1 	  public class ScoreEventTests {
 2 	   static testMethod void TestScoreEvents() {
 3 	   User user1 = new User();
 4 	   user1.FirstName = 'Steve';
 5 	   user1.LastName = 'Will';
 6 	   user1.UserName = 'stevew@submittalexchange.com';
 7 	   user1.Email = 'stevew@submittalexchange.com';
 8 	   user1.Alias = 'swill';
 9 	   user1.CommunityNickname = 'steve';
 10 	   user1.TimeZoneSidKey = 'America/Chicago';
 11 	   user1.LocaleSidKey = 'en_US';
 12 	   user1.LanguageLocaleKey = 'en_US';
 13 	   user1.EmailEncodingKey = 'UTF-8';
 14 	   user1.ProfileId = '00e70000000swZU';
 15 	   insert user1;
 16 	  
 17 	   Account account = new Account();
 18 	   account.Name = 'Test GradeBeam Account';
 19 	   account.Type = 'Architect';
 20 	   account.AD_Rep__c = user1.Id;
 21 	   account.NCA_Rep__c = user1.Id;
 22 	   account.Account_Source__c = 'BSD';
 23 	   insert account;
 24 	  
 25 	   Opportunity opp1 = new Opportunity();
 26 	   opp1.Name = 'Test Opp';
 27 	   opp1.AccountId = account.id;
 28 	   opp1.CloseDate = System.today();
 29 	   opp1.StageName = 'Qualified';
 30 	   opp1.Amount = 100;
 31 	   opp1.OwnerId = user1.Id;
 32 	   opp1.Company_Division__c = 'Textura';
 33 	   insert opp1;
 34 	  
 35 	  
 36 	   opp1.StageName = 'Sales Process';
 37 	   update Opp1;
 38 	  
 39 	   opp1.StageName = 'Written Agreement';
 40 	   update Opp1;
 41 	  
 42 	   opp1.StageName = 'Negotiation';
 43 	   update Opp1;
 44 	   }
 45 	  }
