### Question:
AwsRDSPlatform extends Platform { String getDBSnapshotIdentifier (String dbInstanceIdentifier) { String snapshotIdentifier = AwsRDSUtils.generateSnapshotName(dbInstanceIdentifier); log.debug("{} will use {}", kv(DataDogConstants.RDS_INSTANCE_ID, dbInstanceIdentifier), kv(DataDogConstants.RDS_INSTANCE_SNAPSHOT, snapshotIdentifier)); return snapshotIdentifier; } @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 getDBSnapshotIdentifier () { String dbInstanceIdentifier = UUID.randomUUID().toString(); Instant before = Instant.now().minus(Duration.ofSeconds(1)); String actual = awsRDSPlatform.getDBSnapshotIdentifier(dbInstanceIdentifier); Instant after = Instant.now().plus(Duration.ofSeconds(1)); Matcher m = CalendarUtils.datePattern.matcher(actual); assertTrue("Could not extract date-time from snapshot identifier", m.find()); String dateSection = m.group(1); Instant i = AwsRDSUtils.getInstantFromNameSegment(dateSection); assertEquals(actual, String.format("ChaosSnapshot-%s-%s", dbInstanceIdentifier, dateSection)); assertFalse(before.isAfter(i)); assertFalse(after.isBefore(i)); }
