If there are no parameters on what needs to be shipped at all costs, ship some output from /dev/random and go home.

If you need to ship some functionality in particular, you need a way to check whether what you've written is that functionality.

If you're only releasing once, then maybe a manual/interactive session with the artifact is good enough. But if you're making and releasing frequent changes, then automating the process saves time.
