Yes, in the sigil-query repo on our Github site.

If you build that project in the querytest folder you will build a querytester executable that groks the test_data.dat file and runs all of those tests. Note there are differences in case handling between xthml and html when it comes to attribute names and attribute values. We do case sensitive testing in those cases which xhtml requires.
Let me know if you need help understanding the format.
If you have any good testcases, I would be happy to add them.
