Hello

I am trying to write a test class within this apex class. I have used it before but for some reason this time it is not working. Any ideas?

My error is

Error: InvoiceCloneWithItemsController Compile Error: Method does not exist or incorrect signature: [InvoiceCloneWithItemsController].getInvoiceCloneWithItemsController() at line 68 column 5

public class InvoiceCloneWithItemsController {
 
    //added an instance varaible for the standard controller
    private ApexPages.StandardController controller {get; set;}
     // add the instance for the variables being passed by id on the url
    private miiFinance__Invoice__c po {get;set;}
    // set the id of the record that is created -- ONLY USED BY THE TEST CLASS
    public ID newRecordId {get;set;}
 
    // initialize the controller
    public InvoiceCloneWithItemsController(ApexPages.StandardController controller) {
 
        //initialize the stanrdard controller
        this.controller = controller;
        // load the current record
        po = (miiFinance__Invoice__c)controller.getRecord();
 
    }
 
    // method called from the VF's action attribute to clone the po
    public PageReference cloneWithItems() {
 
         // setup the save point for rollback
         Savepoint sp = Database.setSavepoint();
         miiFinance__Invoice__c newPO;
 
         try {
 
              //copy the purchase order - ONLY INCLUDE THE FIELDS YOU WANT TO CLONE
             po = [select Id, Name, miiFinance__Customer__c, Charged_To_Credit_Card__c, miiFinance__Company_Name__c, miiFinance__Currency__c, miiFinance__Description__c, miiFinance__Due_Date__c, Payment_Allocation__c, miiFinance__Type__c from miiFinance__Invoice__c where id = :po.id];
             newPO = po.clone(false);
             insert newPO;
 
             // set the id of the new po created for testing
               newRecordId = newPO.id;
 
             // copy over the line items - ONLY INCLUDE THE FIELDS YOU WANT TO CLONE
             List<miiFinance__Invoice_Line_Item__c> items = new List<miiFinance__Invoice_Line_Item__c>();
             for (miiFinance__Invoice_Line_Item__c pi : [Select p.Id, p.Name, miiFinance__Amount_Inc_Tax__c, Billed_From_Subscription__c, miiFinance__Currency__c, miiFinance__Display_Name__c, miiFinance__Product_For_Sale__c, miiFinance__Quantity__c, miiFinance__Tax__c, Tax_Amount_Dollars__c From miiFinance__Invoice_Line_Item__c p where miiFinance__Invoice__c = :po.id]) {
                  miiFinance__Invoice_Line_Item__c newPI = pi.clone(false);
                  newPI.miiFinance__Invoice__c = newPO.id;
                  items.add(newPI);
             }
             insert items;
 
         } catch (Exception e){
             // roll everything back in case of error
            Database.rollback(sp);
            ApexPages.addMessages(e);
            return null;
         }
 
        return new PageReference('/'+newPO.id+'/e?retURL=%2F'+newPO.id);
    }

 public static testmethod void Test1()

    {

    miiFinance__Invoice__c p=new miiFinance__Invoice__c();

    ApexPages.StandardController sc = new ApexPages.standardController(p);

           

    InvoiceCloneWithItemsController po=new InvoiceCloneWithItemsController (sc);

    po.getInvoiceCloneWithItemsController();

    }     
 
}

here is my vf page

<apex:page standardController="miiFinance__Invoice__c"
     extensions="InvoiceCloneWithItemsController"
     action="{!cloneWithItems}">
     <apex:pageMessages />
</apex:page>
