Dear All,

  I have a test case code coer proble in my controller we are using pagination the record we are having 2000+ for that we used bellow code how to cover that code with test case

public void lastAction() {        
        bondList = new List<Bond__c>();
        offSetNumber = totRecCnt - Math.mod(totRecCnt, defaultPageSize);
        /*if((totreccnt - offSetNumber) == 0) {
            offSetNumber = totreccnt-defaultPageSize;
        }    */    
        system.debug('..........................'+offSetNumber);
         if(offSetNumber >2000){                 
             searchString = ' Bond_Status__c !=null and recordtypeId = \''+PrivateBond_Helper.retrieveRecordType(Label.PrivateBondRecType)+'\'';
             List<Bond__c> tempBondList = PrivateBond_Helper.RecordsNavigation(searchString);
             if(offSetNumber != totRecCnt){                                   
                  system.debug('.......JA........'+offSetNumber);
                  for(integer recIndex=offSetNumber; recIndex < totRecCnt; recIndex++){
                     bondList.add(tempBondList[recIndex]);  
                  } 
             }else{                 
                  offSetNumber = totRecCnt-defaultPageSize;                  
                  for(integer recIndex=offSetNumber; recIndex < totRecCnt; recIndex++){
                      bondList.add(tempBondList[recIndex]);
                  } 
             }            
        }
}
