Cannot perform simple deletion test

Hi folks,

 

I wrote the following trigger to disallow users to delete Notes of any kind:

 

trigger CannotDeleteNotes on Note (before delete) {
    List<Note> atts = Trigger.old;
    for(Note a:atts) {
    a.addError('In the interest of audit history, the deleting of notes has been disabled.'); 
    }
}

 

 

And the following class to test the trigger:

 

@IsTest
private class Note_Trigger_Test{
    static testMethod void testDelete(){
           Note nots= new Note(Title='Test note');
           Test.startTest();
           Database.DeleteResult result = Database.delete (nots, false);
           Test.stopTest();
           
           System.assert(!result.isSuccess());
           }

}

 

 

But received the following error upon running the test:

 

System.ListException: Missing id at index 0  Class.Note_Trigger_Test.testDelete: line 6, column 1

 

And cannot for the life of me figure out why. The Trigger and the testMethod are both ridiculously simple, but no joy. Am I missing something fundamental?

 

Annoyingly, the Trigger works fine, but I can't deploy it without the code coverage...

 

Thanks for any help you can give,

Lee

Hey 

you forgot to insert

 

 just include the line  

  insert nots;

 

Final code 

 

   

@IsTest
private class Note_Trigger_Test{
    static testMethod void testDelete(){
           Note nots= new Note(Title='Test note');
           insert nots;
           Test.startTest();
           Database.DeleteResult result = Database.delete (nots, false);
           Test.stopTest();
           
           System.assert(!result.isSuccess());
           }

}

Yup. Just realised that, but thank you!

 

Also, when working with Notes, you need to create a parent of some kind (Opportunity, Case etc.) within your test, as Notes cannot exist on their own. Quite easily solved in the end.

 

Thanks
