### Question:
SecretsSerializer { public abstract void loadSecretsMap(Map<String, Secrets> secretsMap);  static synchronized SecretsSerializer get(); abstract void loadSecretsMap(Map<String, Secrets> secretsMap); abstract void serializeSecrets(String name, Secrets secrets); abstract void deleteSecrets(String name);  }### Answer:
@Test public void testLoadSecretsMap() throws Exception { SecretsSerializer serializer = new KeyStoreSecretsSerializer(conf); Map<String, Secrets> secretsMap = new HashMap<String, Secrets>(); serializer.loadSecretsMap(secretsMap); Secrets secrets = secretsMap.get(KEY_ALIAS); SecretKey loadSecretKey = secrets.getSecretKey(); PrivateKey loadPrivateKey = secrets.getPrivateKey(); assertEquals(new String(loadSecretKey.getEncoded(), 0, loadSecretKey.getEncoded().length), new String(secretKey.getEncoded(), 0, secretKey.getEncoded().length)); assertEquals(new String(loadPrivateKey.getEncoded(), 0, loadPrivateKey.getEncoded().length), new String(privateKey.getEncoded(), 0, privateKey.getEncoded().length)); }
