My point is that it's a private function for testing std.stdio and not
intended to be part of the public API or be used by anyone else (it's not
even used anywhere else in Phobos). None of the functions in Phobos that do
that sort of thing are in the public API. You can copy-paste testFilename
(and std.file.deleteme, since it uses that) into your own code and use them
if you like, but the ones in Phobos are just there for Phobos. The only unit
testing-specific functionality that Phobos provides beyond what the language
itself has is in std.exception with functions such as assertThrown.
