The user will indicate that the order should be placed. Tests are a way to write those specifications, force you to think as the user of the code rather than its writer. The user will have a tracking ID for the order. When a program has nothing surprising to say, it should say nothing.
One of Unix's oldest and most persistent design rules is that when a program has nothing interesting or surprising to say, it should shut up. For a program to demonstrate its own correctness, it needs to be using input and output formats sufficiently simple so that the proper relationship between valid input and correct output is easy to check.How to write a job description and person specification.
