Seems like we should test both parsers, no?  Run the same tests through both,
just have a way to allow the old one to fail some?

         StringBuilder output;
         size_t j = 0;
         while (j < querySet->queryVector().size()) {
             String queryText = querySet->queryVector()[j]->cssText();
             output.append(queryText);
             ++j;
             if (j >= querySet->queryVector().size())
                 break;
             output.append(", ");
         }
         if (testCases[i].output)
             ASSERT_STREQ(testCases[i].output, output.toString().ascii().data());
         else
             ASSERT_STREQ(testCases[i].input, output.toString().ascii().data());
     }
 }
