Hey,
I am having issues getting the converage for the apex class (newCom). This class gives users a list of record and they can click any number of cases to attach them to the parent (Billing_Change_Form__c). I am getting 67% coverage but I am not able to cover the else statement lines. 
My apex class (newCom)

// Controller for Billing Form Button on Account

public with sharing class newCom {
	//Declare variables
    public account acc{get;set;}
    public Billing_Change_Form__c comBill {get;set;}
    id acID = System.currentPagereference().getParameters().get('id');
    public list<conCase> caseList{get;set;}
    public boolean bool{get;set;}
    public set<id> caseIds{get;set;}
    ApexPages.StandardController controller;
    public string result{get;set;}
                      
    //Contructor
    public newCom (ApexPages.StandardController con){
        comBill = new Billing_change_form__c();
        id acID = System.currentPagereference().getParameters().get('id');
        comBill.RecordTypeId = '0124A000001lBu9QAE';
        comBill.Account__c = acId;
         controller = con;
        caseList = new list<conCase>();
        bool = false;
        caseIds = new Set<id>();
    }
    
    //Event on clicking the checkbox
    public void inIt(){
        List<Contingency__c> selectedCase = new list<Contingency__c>();
        for(conCase conObj : caseList){
            if(conObj.check != False)
            { system.debug('conObj.con'+ conObj.con);   
             selectedCase.add(conObj.con); 
             caseIds.add(conObj.con.id); bool = true;
            }
               If(conObj.check != true) 
               {caseIds.remove(conObj.con.id); }   
    }
    }
   
    //Displaying the case findings records
   
    public List<conCase> getShow(){
        caseList = new list <conCase> ();

        for(Contingency__c coObj : [Select id, name,billing_type__c, report_description__c, discovery_amount__c,
                        billing_begins_date__c, contingency__c, VENDOR_INVOICE__r.Account_del__r.Id from Contingency__c

                                   ORDER BY NAME])  
        {caseList.add(new conCase(coObj, Bool));}
                                 
        return caseList;
    }

    
    //Event on saving
    public PageReference comInsert(){
        // newBill.RecordTypeId = '0124A000001lBu9QAE';
        // Inserting the new record

        else{

    }
    //Wrapper class for the selected records
       public class conCase{
        public contingency__c con{get;set;}
        public boolean check{get;set;}
        public conCase(contingency__c c, boolean boo){
            con = c;
            check = boo;           
        }
    }
}

My test class

public static testMethod void btnTestCom(){
        
       Account accTest = new Account();
        accTest.Name = 'Test Account';
        insert accTest;
        
       Account accTest2 = new Account();
        accTest2.Name = 'Test Account2';
        insert accTest2;
       
        Account_number__c venTest = new Account_Number__c();
           venTest.Name = 'Test Ven';
           venTest.Account_del__c = accTest.id;

           venTest2.Account_del__c = accTest2.id;
        insert venTest2;
        
         Billing_Change_form__c testBill2 = new Billing_Change_Form__c();
        testBill2.Name = 'Test name2';
         
        testBill2.Reason_for_Removal__c = 'Term Completed';
        testbill2.Reason_what_why__c = 'nada';
       testbill2.Total_Adjustment_Amount__c = 123;
        insert testBill2;
         
          Billing_Change_form__c testBill = new Billing_Change_Form__c();

       testbill.Total_Adjustment_Amount__c = 123;
        insert testBill;

         Contingency__c caseTest = new Contingency__c();
        caseTest.Name = 'test Case';
        caseTest.Contingency__c = 'IN BILLING';
        caseTest.vendor_invoice__c = venTest.id;
        insert caseTest;
        
       Contingency__c caseTest2 = new Contingency__c();
        caseTest2.Name = 'test Case2';
        caseTest2.Contingency__c = 'IN BILLING';
        caseTest2.Bill_form__c = testBill.Id ;
        caseTest2.vendor_invoice__c = venTest2.id;
        insert caseTest2;
       
         Set<id> caseIds = new Set<id>();   
         caseIds.add(caseTest.id);
        	caseIds.add(caseTest2.id);

        Test.startTest();
		
       PageReference pageRef = Page.accBill; // Add your VF page Name here
        pageRef.getParameters().put('id', String.valueOf(testBill.Id));
       Test.setCurrentPage(pageRef);
       
       ApexPages.StandardController sc = new ApexPages.StandardController(testBill);
       newCom  testAccPlan = new newCom(sc);

		 newCre.conCase wrap1 = new newCre.conCase(caseTest2, false);
           wrap1.check = true;
           wrap1.con = caseTest2;
           
           list<newCre.conCase> caseList = new list<newCre.conCase>();
         caseList.add(wrap);
   		 caseList.add(wrap1);

       testAccPlan.inIt();
       testAccPlan.getShow();
       testAccPlan.comInsert();
       testAccPlan.noBill();
       
        test.stopTest();
    }

The uncovered lines in the picture are where the users are click and select the cases.

Any help will be appreciated.
Thanks!​​​​​​​
