# Tests
#
#   Each test must return on success or raise on failure.


#----------------------------------------------------------------------

# Test for issues
#
# #2893 - Handle merge info for portions of a tree not checked out due
#        to insufficient authz.
#
# #2997 - If skipped paths come first in operative merge mergeinfo
#         is incomplete
#
# #2829 - Improve handling for skipped paths encountered during a merge.
#         This is *not* a full test of issue #2829, see also merge_tests.py,
#         search for "2829".  This tests the problem where a merge adds a path
#         with a missing sibling and so needs its own explicit mergeinfo.
#
# #4056 - Don't record non-inheritable mergeinfo if missing subtrees are not
#         touched by the full-depth diff
