_xxtestfuzz crashes if _elementtree is not available #120969
Description
Bug report
Bug description:
Not really sure whether this is intentional but couldn't grep anything relevant: while experimenting with testing whether pure Python fallbacks work the same as C accelerators, I've noticed that _xxtestfuzz crashes immediately if _elementtree accelerator isn't available:
$ ./python -c 'import _xxtestfuzz; _xxtestfuzz.run("")'
ModuleNotFoundError: No module named '_elementtree'
Aborted (core dumped)
$ ./python -m test -w test_xxtestfuzz
