--- Comment #3 from hamano@osstech.co.jp hamano@osstech.co.jp --- Which tests are more likely to fail? So far, many failures have been timing issues. I will work on improving the test. By the way, testing all backends is very expensive, so How about doing manual testing about minor backend instead of per-commit? You will be able to do a full test at the release point.
