walk the dog
v. phr.— «Another one is a sports term known as “walked the dog.” When a reader shared that one with me, it actually was the second time I’d heard it. The first time was from my wife’s cousin, Tony, who was excited about a big win that was produced by the 12-year-old-girls’ softball team he coached. “Aw, man, we walked the dog on that other team,” he said.» —“Walked the dog has me bumfuzzled” by Bernie Delinski Times Daily (Florence, Alabama) Feb. 21, 2007.

too bad it’s not as colorful as the bicyclist ‘walk the dog’, from “faire pisser le chien” — (French) to take the dog out for a leak, to go for an easy ride usually the day after a brutally hard ride.
I heard it used once in a conversation about testing software. By context, it seemed to mean going through all the motions OR a parade of the software functions. Like at a dog show.
