Feature Description
I've been using go-git, and thus go-billy, via the https://github.com/jfontan/go-billy-desfacer library successfully, but it looks like as of v6 billy has stopped using GoCheck and switched to testify.
Unfortunately this makes patching that library difficult because there's no way to just import the billy test suites when implementing a billy-type filesystem anymore, compared to v5 which made this very accessible and very useful.
