I learned about relaxing when it's hopeless from this passage long ago:

Zaphod tried to run in several equally decisive directions simultaneously. "Right!" he said. "Er ... we've got to get manual control of this ship."

"Can you fly her?" asked Ford pleasantly.

"No, can you?"

"No."

"Trillian, can you?"

"No."

"Fine," said Zaphod, relaxing. "We'll do it together."

James Coplien wrote in 2014 I think a paper titled "Why most unit testing is waste" which stirred up a storm among developers. I've seen many rebuttals, and they keep cropping up every year, but most seem to agree with his core premise: unit testing is valuable for testing algorithms -- stateless functions performing a computation -- and not much else.
