bsl::string* message,
bsl::basic_string_view<char> expectedResult,
bool alsoTestOracle,
std::format_string<t_TYPE, t_ARG> fmt,
t_TYPE&& value,
t_ARG&& arg);Compare the specified expectedResult with the result of formatting the specified value and arg with the specified fmt obtained using a bslfmt::formatter specialization for the (template parameter) t_TYPE. If the specified alsoTestOracle is true, also compare the expectedResult with the result of formatting obtained using standard library implementation. Return true if these strings are equal, otherwise store a description of the error in the specified output message and return false. Note that fmt is required to be a compile time constant expression.
true if formatting matches expectedResult, else false.

| alsoTestOracle | If true, also compare against the standard library formatter. |
