What's changed and what's your intention?
For now,
KvBackend
trait has some implements, such asChrootKvBackend
,MemoryKvBackend
, etc. But onlyRaftEngineBackend
,MemoryKvBackend
andEtcdStore
will directly access the data. PR #2615 has been added some tests forRaftEngineBackend
andMemoryKvBackend
, this PR forEtcdStore
to ensure all implements have the same behaviors.Other
KvBackend
trait implements basedRaftEngineBackend
,MemoryKvBackend
andEtcdStore
implement,I think it's unnecessary.Tests mainly for range、put、batch_put、batch_get、compare_and_put、delete_range、batch_delete.
