That often fails to install and internally it forks, giving up much of the performance benefit I want. In the meantime, I've just uploaded a proof of concept named Test::Aggregate because it attempts to take a bunch of tests and aggregate them together.

test suite as CPAN module
I've been working on Test::Virtual::Filesystem for a couple of weeks. It's a growing collection of interoperability tests that should pass for any typical filesystem. I've been pondering its place in the CPANiverse and am interested in any insights others may have. * Unlike most of the Test::* modules, this is not a tool for writing tests. Instead, it is a suite of complete tests that should be applied to a filesystem. * It tests conformance to an API instead of an implementation. In this case, the API is the collection of core Perl filesystem functions. * The distro tests itself against a known, stable filesystem (/tmp or the equivalent) but is intended to be used to test less stable filesystems (like Fuse filesystems -- I use it for Fuse::PDF) I searched CPAN (admittedly lightly) for any similar suites and didn't find anything else expressly designed for such a purpose. Questions: * Are there other CPAN-hosted, generic test suites that I overlooked? * What other stable, popular APIs would benefit from a reusable test suite? * Is it worth pushing others to write and use test suites like this, possibly replacing existing ad hoc tests (see, for example, the Fuse.pm .t files) I came across some non-Perl generic test suites (filesystem and otherwise), but many were optimized for benchmarking rather than API completeness. I've read about a few others, like the Neon webdav test suite, but again saw little to nothing in the Perl world quite like that. A notable exception is the PUGS test suite, which fits in this category in that it's intended to work against any Perl 6 implementation. The controversial Java TCK lives in this space too. In fact, the strong separation of Interface from Class in the Java world pushes towards this style of testing more naturally than in Perl. In general, it has occurred to me many times that writing good tests can be as hard as writing good code, but that we rarely reuse them, unlike our code itself. Thoughts? Chris

(It works for all of my modules appropriately.) Don't forget that to make CPAN.pm install a dev release (ie one with a _ in its name) then you need to tell it to install the distribution name (CHROMATIC/UNIVERSAL-isa-1.00_00.tar.gz), because if you give it just a module name it installs the latest *release* version.

[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

It's a growing collection of interoperability tests that should pass for any typical filesystem. Could it also be used for detecting what features a mounted filesystem supports? eg, does this filesystem support hard links and does this filesystem support Unix-style permissions? 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. -- David Cantrell | A machine for turning tea into grumpiness You know you're getting old when you fancy the teenager's parent and ignore the teenager -- Paul M in uknot
