During some other work I discovered these tests weren't great, so I've rewritten them to be a little better. The real changes here are: - Don't play games with not starting the folder and such, and don't construct a fake folder instance -- just use the one the model has. The folder starts and scans but the folder contents are empty at this point so that's fine. - Use a fakefs instead of a temp dir. - To support the above, implement a fakefs option `?content=true` to make the fakefs actually retain written content. Use sparingly, obviously, but it means the fakefs can usually be used instead of an on disk real directory.
