### Question:
AwsRDSPlatform extends Platform { public void deleteClusterSnapshot (DBClusterSnapshot dbClusterSnapshot) { log.info("Deleting RDS Cluster Snapshot {}", v(DataDogConstants.RDS_CLUSTER_SNAPSHOT, dbClusterSnapshot)); amazonRDS.deleteDBClusterSnapshot(new DeleteDBClusterSnapshotRequest().withDBClusterSnapshotIdentifier(dbClusterSnapshot .getDBClusterSnapshotIdentifier())); } @Autowired  AwsRDSPlatform();   AwsRDSPlatform(AmazonRDS amazonRDS, AmazonEC2 amazonEC2); Map<String, String> getVpcToSecurityGroupMap(); @Override ApiStatus getApiStatus(); @Override PlatformLevel getPlatformLevel(); @Override PlatformHealth getPlatformHealth(); @Override List<Container> generateExperimentRoster(); @Override boolean isContainerRecycled(Container container); Map<String, String> getFilter(); void setFilter(Map<String, String> filter); void failoverCluster(String dbClusterIdentifier); void restartInstance(String... dbInstanceIdentifiers); Set<String> getClusterInstances(String dbClusterIdentifier); ContainerHealth getInstanceStatus(String... dbInstanceIdentifiers); void setVpcSecurityGroupIds(String dbInstanceIdentifier, String vpcSecurityGroupId); void setVpcSecurityGroupIds(String dbInstanceIdentifier, Collection<String> vpcSecurityGroupIds); ContainerHealth checkVpcSecurityGroupIds(String dbInstanceIdentifier, Collection<String> vpcSecurityGroupIds); Collection<String> getVpcSecurityGroupIds(String dbInstanceIdentifier); String getChaosSecurityGroup(String dbInstanceIdentifier); DBSnapshot snapshotDBInstance(String dbInstanceIdentifier); DBClusterSnapshot snapshotDBCluster(String dbClusterIdentifier); void deleteInstanceSnapshot(DBSnapshot dbSnapshot); void deleteClusterSnapshot(DBClusterSnapshot dbClusterSnapshot); boolean isInstanceSnapshotRunning(String dbInstanceIdentifier); boolean isClusterSnapshotRunning(String dbClusterIdentifier);  }### Answer:
@Test public void deleteClusterSnapshot () { String dBClusterSnapshotIdentifier = randomUUID().toString(); DBClusterSnapshot dbClusterSnapshot = new DBClusterSnapshot().withDBClusterSnapshotIdentifier(dBClusterSnapshotIdentifier); doReturn(null).when(amazonRDS).deleteDBClusterSnapshot(any()); awsRDSPlatform.deleteClusterSnapshot(dbClusterSnapshot); verify(amazonRDS, times(1)).deleteDBClusterSnapshot(new DeleteDBClusterSnapshotRequest().withDBClusterSnapshotIdentifier(dBClusterSnapshotIdentifier)); }
