bool
testParseFailure(
bsl::string* message,
bool alsoTestOracle,
bsl::basic_string_view<wchar_t> fmt);Verify that the specified fmt has a valid structure and, if so, parse it using a bslfmt::formatter specialization for the (template parameter) t_TYPE. If the specified alsoTestOracle is true, also parse fmt using a standard library implementation. Return true if fmt is valid and the exception IS thrown during the parsing, and return false otherwise.
true if parsing fails as expected, else false.
