Tester: And this error case tests that for any individual adult, only one infant can fly with them. The test case is for one adult, five infants. The error should be caught by the UI.
Me: Hell, if I'm on that plane, I'll kick them off myself.
Tester: This test checks that for a flight search with an INF, that the infant is promoted to an adult under certain error conditions.
Developer: Uh, no, that's only for INS, infant in seat. An INFant in lap can't go as an adult.
Tester: Yeah, you don't want to be flying with an adult in your lap.
Developer: I'm not touching that.
