Like, Parsoid's round-trip testing, we should do DM round-trip testing with content from Wikipedia. dirtydiffbot does this to some extent, but it tests the Parsoid output rather than the DM output and it uses the UI, which is hacky. We should have a proper service that just tests the DM HTML output is clean, which requires a test runner for that purpose in VE.
