A quick guide to ZOMB+E
Zero checks if there is anything so not null or "" or if exist
One cheks if there are an instance of a class or value
like two people cant have same phone number
Many it checks in an array if something happens when values
are inserted and values are removed
Boundaries testing the limits like a phone number can only contain 8 numbers
so there cant be 7 or 9
Exercise exceptional behavior if an error occurred the aplication will say ex
"Error phonenumber to long" or "Error phonenumber to short"
