I have written the following trigger, however I'm unable to cover the following lines in my test class. Unable to figure out what I'm missing. Thank you in advance for everyones help!


Here is the trigger:

trigger SetCaseDetails on Case (before insert, before update) {
    Id ITSRecordID = Olympus__c.getOrgDefaults().ITS_Case_Record_Type__c;
    Id TechRecordID = Olympus__c.getOrgDefaults().TechSupportID__c;
    Map<Id, Case> parentCaseOwners = new Map<Id, Case>();
    Map<String, Repair_History__c> repairHistories = new Map<String, Repair_History__c>();
    for (Case c : Trigger.new) {
        if (c.ParentId != null) {
            parentCaseOwners.put(c.ParentId, null);
        }
        if (c.SO__c != null) {
            repairHistories.put(c.SO__c, null);
        } if (c.Status == 'Closed' || c.Status == 'No Bid' || c.Status == 'Complete' || c.Status == 'Cancelled') {
            c.Open_Lookup__c = null;
       } else if (c.AccountId != null) {
            c.Open_Lookup__c = c.AccountId;
        }
    }    
    if (!parentCaseOwners.isEmpty()) {
        for (Case pc: [SELECT Id, OwnerId FROM Case WHERE Id in :parentCaseOwners.keySet()]) {
            parentCaseOwners.put(pc.Id,pc);
        }        
        for (Case c : Trigger.new) {
            if (c.ParentId != null & c.RecordTypeID != ITSRecordID & c.RecordTypeID != TechRecordID) {
                c.OwnerId = parentCaseOwners.get(c.ParentId).OwnerId;
            }
        }
    }   
    if (!repairHistories.isEmpty()) {
        for (Repair_History__c rh : [SELECT Id, Account__c, Repair_Number__c, Product__c FROM Repair_History__c WHERE Repair_Number__c in : repairHistories.keySet()]) {
            repairHistories.put(rh.Repair_Number__c, rh);
        }        
        for (Case c : Trigger.new) {
            if (c.SO__c != null && repairHistories.get(c.SO__c) != null) {
                c.Repair_History__c = repairHistories.get(c.SO__c).Id;
                c.ProductId = repairHistories.get(c.SO__c).Product__c;
                if (c.AccountId == null && repairHistories.get(c.SO__c).Account__c != null) {
                    c.AccountId = repairHistories.get(c.SO__c).Account__c;
                }
            }
        }
    }
}

Here is the test class:
 

@isTest

  static testMethod void test() {       
        List<Repair_History__c> repairhistories = new List<Repair_History__c>();

        );
        insert a1;
        
        case c1 = new Case(

            Open_Lookup__c=a1.id,
            accountid=a1.id
        	);
        insert c1;
      newMap.put(c1.id,null);
      caseowners.add(c1);
      
     	case c2 = new Case(

            SO__c='12345678',
            RecordTypeId=caserec
        	);
        insert c2;
      newMap.put(c2.id,null);

        	);
        insert c3;
      
      caseowners.add(c2);
      
        Account a2 = new Account(
            Name = 'A2',
            JDE_Account_Number__c='JDE',
            ParentId=a1.Id,
            BillingStreet = 'Street',
            BillingCity = 'City',
            BillingPostalCode = 'Postal Code',
            BillingState = 'ON',
            BillingCountry = 'Country'
        );
        insert a2;
        
      	Repair_History__c p1 = new Repair_History__c();
            p1.Repair_Number__c  = '123456';
            p1.Total_Price__c  = 100;
            p1.Account__c = a1.Id;
            insert p1;
      
      	Repair_History__c p2 = new Repair_History__c();
            p2.Repair_Number__c  = '1234567';
            p2.Total_Price__c  = 100;
            p2.Account__c = a2.Id;
            insert p2;
      
      	repairhistories.add(p1);
        repairhistories.add(p2);
      
    }
