Seems like you could just put your test files in a tmpfs, if leaving files laying around is an issue.

You need to mount and unmount fikesystems to do that.

Take a look at the library mentioned,afero, and you'll see how nice it handles working with the file system in tests.

You can have everything in memory, and a whole new fs in each test

The problem is it only tests trivial properties of the API. That might be enough for some things, but it’s not a panacea.
