Moretesting

Wrote some tests to deal with non-typed and empty string phone numbers.  I tried testing for vars.lead.phone_1 != '' but for whatever it didn't handle that as expected, so I changed to testing for the min length of a phone number that might possibly make sense.  
as I read the previous test, it was a single 'before' set, but I can do a beforeEach.  do you have any recommendation on how to test only alternate phone number options using a beforeEach?
