Here is my test code

        static testMethod void TestXXCSRLeadConvertClass() {
      
       test.startTest();
           Boolean bolCreateOpp;
           String strAccountId;
     String strContactId;
            Lead l = new Lead();
            l.FirstName = 'CRM Testing First';

            insert l;
       
      Id leadId = l.Id;
  bolCreateOpp = false;
  //Create a reference to the VF page
  PageReference pageRef = Page.XXCSR_LEAD_CONVERT;
        Test.setCurrentPageReference(pageRef);

     //Create an instance of the controller extension and call the autoRun method.
  //autoRun must be called explicitly even though it is "autoRun".
  ApexPages.StandardController sc = new ApexPages.standardController(l);
  XXCSRLeadConvertClass leadconvt = new XXCSRLeadConvertClass(sc);
   String nextPage = sc.save().getUrl();
 
      
       List<SelectOption> testacct = new List<SelectOption>();
