Without the PR, main branch:

$ ./python -m test -v test_xml_etree_c

With the PR:

$ ./python -m test -v test_xml_etree_c
(...)
Total tests: run=208 skipped=6
Total test files: run=1/1

regrtest is able to count the number of tests, nice!

I counted manually the number of tests in the main branch (count the number of lines in short), and I also see 208 tests! I only see 5 skipped tests, but here 6 are announced. Aha, interesting!

I only see 5 skipped tests, but here 6 are announced.
