Sometimes test runners allow to specify the junit xml (for instance pytest).
It makes really simple to retrieve info from unit engine. We "just"

• create a new Tempfile
• pass this file to feature

But some unit engines doesn't allow to specify the file.
Rather they (most of the time) allow to specify a directory for xml output.
Is theire a connonical way to retrieve the xml output in this case:

• In fact, I didn't find a TempDir in liphutil/src/filesystem/. Something like TempFile will be cool to ensure that phab delete the dir after the object is deleted.
• It would be cool if TempDir wrapper as a mecanism to get the file in the dir matching a filter

Before reinventing the wheel :

• does a similar mecanism exists
• if not, is upstream interessed by such a wrapper ?
