That's actually a Safari feature, not a WebKit feature. It's
something the Safari team made for our own internal use. We haven't
done anything to try to make it useful for people outside our team or

You can make a file listing tests and giving it the ".pltsuite"
extension, then put it in the Safari application's Contents/Resources
directory. This is not something you'd generally want to do because
it requires modifying your local copy of Safari.

This is not a WebKit feature. It's a Safari feature. It's not open
source, which is why you can't find the code.
You could make something like this that was independent of Safari;
with a little work I'm sure you could come up with something far more
I'm not sure what you're using this for. The Safari team uses it to
gauge the speed of Safari.
