Thoughts? Fuse::PDF caught my eyes a few days ago (how could it not with that name ;) although I still wonder if it has any serious use) and having a test suite for a file system that can be reused is an excellent idea. You're right, very few tests suits are reusable. I know of standard tests for C++ that vendors can qualify against but except that not much. Other domains tha could be interresting to have generic tests suits for are: - load balancing/scheduling - network protocol - database I'm planning to write a fuse based FS so your test suit will come handy.

The hard bit is doing that while taking into account mount options. eg, on Mac OS X, you can mount a UFS filesystem (which supports Unix-style perms) but tell the system to ignore permissions altogether. The *really* hard bit is to do that as an unpriveleged user and without making any changes to the fs. If so, then I can see immediate uses for it in a couple of my projects. I certainly can see a use for something like that, but Test-Virtual- Filesystem would not serve as a good base. It deliberately tries not to probe the limits of the filesystem nuances (like how many symlinks do you have to follow before you get an ELOOP error = 5 on Linux, but at least 10 on other *nixes).

[1] http://search.cpan.org/dist/Apache-Test/ Actually it does something slightly different from what I thought it did. It lets you build a test suite to verify a particular Apache based application I believe. Thanks to Paul Johnson for the correction. -- Andy Armstrong, Hexten
