I'm trying to get the step -2 and while running the supplied Apex Test, 
Getting below error 

ClassBeAwesome
Method NamehugYourMother
Pass/FailFail
Error MessageSystem.QueryException: List has no rows for assignment to SObject
Stack TraceClass.sb_security.BeAwesome.createUser: line 89, column 1
Class.sb_security.BeAwesome.setup: line 81, column 1

I have created the records owned by Samantha as mentioned and also created sharing rule for Project managers.
Can someone please help ?
