Which way is the happy path?

In this week’s BYTE Newsletter, the article The Software Development Dilemma (subscription required) introduces the term “happy path”.

“[T]he “happy path,” a default scenario with no exceptional conditions. (The “happy path” concept originated with Richard Harrah, an HP software developer…)”

I like it. There are lots of times that I refer to the happy path when talking about how much testing some code has had, and now I have a phrase for it.
