I'm not sure what might be going on here.  I can tell you that I've never
tested Athena on either of those platforms, though.

When I run `nit nevow´ and click the `Run Tests´ button, I see 59 tests
run and succeed.  This using Firefox 1.5 on Ubuntu 6.06.

You might be confusing nits with JavaScript unit tests.  nits are defined
by livetest_*.py files and whatever JavaScript the `jsClass´ attributes in
them point to.  Much (perhaps not, there's a bit of mixing) of the code in
the Nevow.Test JavaScript package (defined by Nevow/nevow/js/Nevow/Test/)
is for JavaScript unit tests.  These are run using the stand-alone spider-
monkey interpreter; they don't run in a browser.

Nevow/nevow/js/Nevow/Athena/Tests/__init__.js has most of the code for the
Nevow nits.
