Don't Dial Every Number
Scenarios can be automated but they are not a comprehensive set of tests
to be created far in advance of implementation.If you're using a phone, you don't need to dial every number to verify that it works:
a few samples, plus some important special cases such as 911, can give you that confidence.Redundant scenarios slow you down and hinder communication and understanding;
if you truly need them, add them to a comprehensive regression suite.
Don’t dial every number:
Select scenarios that cover the logic pathways with little redundancy.
