> *Why unit test TestRaftSnapshotWithGrpc.testBasicInstallSnapshot failed?*
> In the test, leader take snapshot, then add two followers, then [leader
> restart|https://github.com/apache/incubator-ratis/blob/master/ratis-server/src/test/java/org/apache/ratis/statemachine/RaftSnapshotBaseTest.java#L234],
> then
> [verifyTakeSnapshotMetric|https://github.com/apache/incubator-ratis/blob/master/ratis-server/src/test/java/org/apache/ratis/statemachine/RaftSnapshotBaseTest.java#L236].
>
> It must be failed when verifyTakeSnapshotMetric after restarting leader.
> Because restart leader will create a new instance of RaftServer, the metric
> of take snapshot is clean.
> *How to fix ?*
> verifyTakeSnapshotMetric after leader take snapshot.
