What real world product did the designers of the D language do?

I think he's talking about unit tests in general D code, not unittests in Phobos.

Sure. Just would have thought that maybe some unit-testing D user out there had written a function that wrote something to a file ;-)

But no problem -- not many lines to add to  my own code.

I've written unittests that create files to test code with.

However, I never thought far enough to make it something generic that can be used elsewhere. :-) So I use actual filenames (not tmpfiles) so that later unittests can reference actual filenames to load different datasets into the program for testing. Not the nicest solution, since it will overwrite files in the working directory, but presumably only developers will bother running unittests anyway so this shouldn't be a problem.
