It would be great if you want to tackle this!
Start off by absorbing subversion/tests/clients/cmdline/README; it
will give you an overview of how our python tests work.

Our test framework already does this for every test.

Easily doable; our test framework already uses dump/load to create a
new repository for each test.

Multiple checkouts will work fine. And our test framework is already
built around the idea of comparing trees: disk trees, 'svn status'
trees, and trees that result from parsing 'svn co/up' output.

Sounds good.

No, no need to write a dumpstream generator/parser in python. The
whole point of our python tests is that the use the binary tools as
"black boxes", just like a user would. They're already invoking {svn,
svnadmin, svnlook}. You would just be adding 'svndumpfilter' to the
list.
