Check

FilledSmallSquareCheck[expr, failexpr] evaluates expr, and returns the result, unless messages were generated, in which case it evaluates and returns failexpr.

FilledSmallSquareCheck[expr, failexpr, ::, ::, ... ] checks only for the specified messages.

FilledSmallSquareCheck has attribute HoldAll.

FilledSmallSquareCheck tests only for messages that are actually output. It does not test for messages that have been suppressed using Off.

FilledSmallSquare See The Mathematica Book: Section 2.8.21.
