### Question:
KerberosServerAction extends AbstractServerAction { protected static KDCType getKDCType(Map<String, String> commandParameters) { String kdcType = getCommandParameterValue(commandParameters, KDC_TYPE); return ((kdcType == null) || kdcType.isEmpty()) ? KDCType.NONE : KDCType.translate(kdcType); }   static final String AUTHENTICATED_USER_NAME; static final String DATA_DIRECTORY; static final String DEFAULT_REALM; static final String SERVICE_COMPONENT_FILTER; static final String HOST_FILTER; static final String IDENTITY_FILTER; static final String KDC_TYPE; static final String UPDATE_CONFIGURATION_POLICY; static final String UPDATE_CONFIGURATION_NOTE; static final String DATA_DIRECTORY_PREFIX; static final String KEYTAB_CONTENT_BASE64; static final String OPERATION_TYPE; static final String INCLUDE_AMBARI_IDENTITY; static final String PRECONFIGURE_SERVICES; }### Answer:
@Test public void testGetKDCTypeStatic() throws Exception { Assert.assertEquals(KDCType.MIT_KDC, KerberosServerAction.getKDCType(commandParams)); }
