There were two failures in 1.11 on tests.

and it seems they still exist in trunk.

on FreeBSD 11.1, Python 3.7.0, Subversion trunk@1868235:

]]]

The former failure can be fixed by attached patch, fix_svnadmin_tests_patch.txt

The latter also can be fixed by fix_tree_conflict_tests_patch.txt
at least so that the test can be passed on Python 3. However, from above
stack trace, I think it is incomplete because there still exists some sort of
confusion between bytes and str in subversion/tests/cmdline/svntest/*.py
