So there is no class support Lagrange based discontinuous
polynomial space? If the answer is no, I think it is pretty easy
to add one. Just need the shape function and the DOF locations.
I added a discontinuous Lagrange FE type earlier this year:

IIRC that describes all of our discontinous element types,
it shouldn't be an issue using DG.
There may still be a bug in some of our hp constraint equation
a couple corner cases. However if you're doing DG there's no
constraint equations and again the concern won't apply.
Our unit testing is deplorable - the unit test suite gets
P.S. How about the test coverage of the code? I found out

Thanks a lot.
automatically run every several hours, but as you noticed the
are quite old and the test coverage is very incomplete. If
enough free time or gets bored enough to contribute to these,
be highly appreciated.
Our regression testing is a little better - the examples in
itself aren't rigorous enough as regression tests (they
just catch logic failures using library internal assertions
accuracy failures via manual examination), but both UT-Austin
have a few suites of libMesh application tests that get run
with varying configurations and parameter settings and get
automatic solution comparison.
I say only "a little better" because there are still gaps in
feature coverage - I don't think we've got anything that hits
p-adaptivity, in particular.
