Full diff for list of strings wrong for multi-line string #10863
Description
When running this snippet using pytest -v test.py, the full diff output confuses me and I believe the first item with a "-" is wrong there.
# ./test.py def test_(): m = [ "This is some dummy test which shows the strange way in which Pycharm" " displays the full diff." ] assert m == []Output:
FAILED [100%] test_fulldiff.py:0 (test_) ['This is some dummy test which shows the strange way in which Pycharm ' 'displays the full diff.'] != [] <Click to see difference> def test_(): m = [ "This is some dummy test which shows the strange way in which Pycharm" " displays the full diff." ] > assert m == [] E AssertionError: assert ['This is some dummy test which shows the strange way in which Pycharm displays the full diff.'] == [] E Left contains one more item: 'This is some dummy test which shows the strange way in which Pycharm displays the full diff.'
