The failed assertion for this test was

OpenSearch/server/src/test/java/org/opensearch/cluster/routing/allocation/IndexShardHotSpotTests.java

Line 66 in 996d33a

assertTrue(movesForModeUnassigned <= movesForModeNone);

but the test was refactored in the commit 5dfd05c. The failed assertion was removed, because the author of the above commit thought it was useless and confusing, seeing from the commit description and the comment here https://github.com/opensearch-project/OpenSearch/pull/680/files#r745565395.
I think it's fair to close this issue.
