Hi all,

I am pasting below my apex class and test class. I am getting accID as null. Please help me where i am going wrong.

    ApexPages.currentPage().getParameters().put('id',acc.Id);  in test class.
Hope this works

Hi Bhanu,

I got the accid. But now stuck at line no 73.. where i have the checkbool condition. How do i add it in test class?
Asif Ali MAsif Ali M
You are not getting the coverage for assignNotes method because your wrapper classes have a default value FALSE on checkBool property. Add these 2 lines after you created ContactWrapper ad OpprtunityWrapper object.
objwrap.checkBool = true;
objwrap1.checkBool = true;

Hi Asif,

okay i will do that and let you know if it works
Amita TatarAmita Tatar
Hi Asif,
I incuded those two lines, still test is getting failed and giving me null pointer exception
Asif Ali MAsif Ali M
Null pointer exception will generally occur when you are trying to access a property on an object when it is null. 
Can you please share the full error message?
Bhanu joshi 10Bhanu joshi 10


The boolean is  false because when you are adding a note in wrapper class it make it always false.(see you line 39 and 104.
Pass two paremeter one for object and other for Boolean.
Hope this works !!
