Hello All,

I have been able to write a trigger with "bulkification" but I am having problems understanding how to write the test class to cover all lines.

Here is the code that I am trying to cover.

trigger ContactOpportunityAssoc on Contact (after insert) {
set<String> custnmbr = new set<String>();
		for (Contact c: Trigger.new){
            if (c.cnt_plcsc_CustNmbr_ExtID__c != null){custnmbr.add(c.cnt_plcsc_Customer_Number__c);}
        }
        
Map<String,Id> mapOpps = new Map<String,Id>();
/*List all Contacts that have the customer number the same as the loaded custnmbr set*/      
		for(Opportunity opp: [Select Id, Customer_Number__c 
							From Opportunity 
							Where Customer_Number__c IN: custnmbr]){mapOpps.put(opp.Customer_Number__c , opp.Id);}

set<String> oppids = new set<String>();
		for(Opportunity opp2: [Select Id, Customer_Number__c 
								From Opportunity 
								Where Customer_Number__c IN: custnmbr]){oppids.add(opp2.Id);}

Map<String,Id> mapCnts = new Map<String,Id>();
/*List all Contacts that have the customer number the same as the loaded custnmbr set*/      
		for(Contact cnt: Trigger.new){mapCnts.put(cnt.cnt_plcsc_Customer_Number__c , cnt.Id);}
		
/*Loop through the main list of Cnts*/
List<OpportunityContactRole> ocr = new List<OpportunityContactRole>();
List<Opportunity> oppsList = [Select Id, Customer_Number__c From Opportunity Where Customer_Number__c In: custnmbr];

			for(Opportunity o2: oppsList){
				if(mapOpps.containsKey(o2.Customer_Number__c)){
						OpportunityContactRole ocr2 = new OpportunityContactRole();
						ocr2.ContactId = mapCnts.get(o2.Customer_Number__c);
						ocr2.OpportunityId = o2.Id;
						ocr2.IsPrimary = true;
						ocr2.Role = 'Primary Insured';
						ocr.add(ocr2);
				}
			}
/*Insert the new list of OCR's*/
	if(!ocr.isEmpty()){
		insert ocr;}
}

 Here is my sad attempt at code coverage:

Contact cntExisting = new Contact(LastName = 'Tester');
			cntExisting.FirstName = 'Test';
			cntExisting.RecordTypeId = '01240000000DVfaAAG';
			cntExisting.Email='test@hanover.com';
			cntExisting.cnt_plcsc_CustNmbr_ExtID__c = '123456789INS01';
			cntExisting.cnt_plcsc_Customer_Number__c='123456789';
			cntExisting.MailingPostalCode = '01453';
			String cntId = cntExisting.Id;
		insert cntExisting;
		
		cntExisting = [Select Id, Name, cnt_plcsc_Customer_Number__c from Contact Where Id=:cntExisting.Id];
    	System.assertEquals('123456789', cntExisting.cnt_plcsc_Customer_Number__c);
    	
    	Map<String,Id> mapCntpRecs = new Map<String,Id>();
    		for(Contact mapcnts:[Select Id, cnt_plcsc_Customer_Number__c from Contact Where cnt_plcsc_Customer_Number__c=:cntExisting.cnt_plcsc_Customer_Number__c]){
    			mapCntpRecs.put(mapcnts.cnt_plcsc_Customer_Number__c, mapcnts.Id);}
    		
    	Contact cntExisting2 = new Contact(LastName = '2Tester');

    	OpportunityContactRole ocrInsert = new OpportunityContactRole(OpportunityId = otherPol1.Id, ContactId = cntExisting2.Id);
    			ocrInsert.IsPrimary = true;
    			ocrInsert.Role = 'Primary Insured';
    			insert ocrInsert;
    	
    	Map<String,Id> mapOppRecs = new Map<String,Id>();
    		for(OpportunityContactRole mapoppscntr:[Select Id, ContactId, OpportunityId from OpportunityContactRole Where OpportunityId=:otherPol1.Id]){
    			mapOppRecs.put(mapoppscntr.OpportunityId, mapoppscntr.Id);} 
    						     
		List<OpportunityContactRole> ocrs=new List<OpportunityContactRole>();
		List<Opportunity> oppsList = [Select Id, Customer_Number__c From Opportunity Where Id In: oppids];
		for(Opportunity o2:oppsList){
			if(mapOppRecs.containsKey(o2.Customer_Number__c)){
				OpportunityContactRole ocr2 = new OpportunityContactRole(OpportunityId = otherPol.Id, ContactId = cntExisting2.Id);

		        		ocr2.IsPrimary = false;

 Any help would be greatly appreciated.  :)
