 *
 * @return The string that is returned can be
 *     customized per type by conforming a type to the `TestOutputStringConvertible`
 *     protocol. When stringifying a non-`TestOutputStringConvertible` type, this
 *     function will return the value's debug description and then its
 *     normal description if available and in that order. Otherwise it
 *     will return the result of constructing a string from the value.
