test class coder coverage issue

Hi all,

I have a test class and i am not able to increase its code coverage.
I am posting my apex class and test class code.
Apex Class----------------------------------------

public class DisplayNotesNew{

public List<WrapperClass> listWrapper {get;set;}
public List<ContactWrapper> listWrapper1 {get;set;}
public List<OpportunityWrapper> listWrapper2 {get;set;}

public void assignNoteId() {
   Id note = ApexPages.currentPage().getParameters().get('note');
   system.debug('18-->'+note );
   if(note != null) {
      noteID = note;

public DisplayNotesNew(){
public DisplayNotesNew(ApexPages.StandardController Controller) {

accId = ApexPages.currentPage().getParameters().get('id');
List<Note> listAcct = [SELECT Id,Title, Body,Parent.Id,CreatedDate FROM Note where Parent.Id =: accId order by ID DESC];
  if(listAcct.size() > 0) {
    listWrapper = new List<WrapperClass>();
       for(Note a : listAcct) {
          listWrapper.add(new WrapperClass(a));

List has no rows for assignment

in which line??

Amita TatarAmita Tatar
Class.DisplayNotesNew.assignNotes: line 57, column 1
Class.DisplayNotesNewTestClass.test1: line 37, column 1

The query which is fetched from noteid gives this error, because it does not get the noteID
Devanshu soodDevanshu sood
try to insert note
note n=new note(........................);
then use

and let me know if it works

Note note = new Note(parentid = acc.Id,title='test',body= 'hi');
