Yes. To test some specific OpenType MATH feature we already use our own
small fonts (a few kilobytes) loaded as Web fonts. However, for all the
other tests with real math fonts (where we want to get reliable
rendering and independent of which of these math fonts are installed or
not), it's not clear whether the license (compatibility with WebKit's?)
or the size (several hundreds of kilobytes) make that
possible/judicious. For WebKitGTK+ we have the separate repository of
fonts  mentioned in my previous mail that ensures Latin Modern Math
is available when running GTK tests.

I agree with that. I'd just like to note that:
a) From my experience, installing user font in the Apple Font Book does
not even seem enough. For some reason, only the pre-installed font are
used when running tests...
b) As said above, WebKitGTK+ has a special mechanism to setup a jhbuild
environment and automate installation of dependencies ; I was wondering
if something similar exists for the Apple ports, but apparently that's
not the case...

Yes, I expected that. However, some years ago Apple accepted to install
the STIX font version 1.0. So I was hoping that maybe an upgrade to
version 2 when it is released would not be asking too much... at least
compared to the burden of managing a jhbuild-like mechanism in Apple
ports or bundling big fonts into the repo...

Can you elaborate on what is done for WebKitWeightWatcher?
