### Question:
AwsRDSPlatform extends Platform { public void deleteInstanceSnapshot (DBSnapshot dbSnapshot) { log.info("Deleting RDS Instance Snapshot {}", v(DataDogConstants.RDS_INSTANCE_SNAPSHOT, dbSnapshot)); amazonRDS.deleteDBSnapshot(new DeleteDBSnapshotRequest().withDBSnapshotIdentifier(dbSnapshot.getDBSnapshotIdentifier())); } @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 deleteInstanceSnapshot () { String dBSnapshotIdentifier = randomUUID().toString(); DBSnapshot dbSnapshot = new DBSnapshot().withDBSnapshotIdentifier(dBSnapshotIdentifier); doReturn(null).when(amazonRDS).deleteDBSnapshot(any()); awsRDSPlatform.deleteInstanceSnapshot(dbSnapshot); verify(amazonRDS, times(1)).deleteDBSnapshot(new DeleteDBSnapshotRequest().withDBSnapshotIdentifier(dBSnapshotIdentifier)); }
