### Question:
RxtUnboundedFieldManagerService extends AbstractAdmin { public void setActiveTenantsUnboundedFields(String rxtConfig) throws RegistryException { int tenantId = PrivilegedCarbonContext.getThreadLocalCarbonContext().getTenantId(); UserRegistry registry = Utils.getRegistryService().getRegistry(); Map<String, List<String>> tenantRxtUnboundedEntries = RxtUnboundedDataLoadUtils.getRxtData(registry); allTenantsUnboundedFields.put(tenantId, tenantRxtUnboundedEntries); }  static RxtUnboundedFieldManagerService getInstance(); Map<Integer, Map<String, List<String>>> getTenantsUnboundedFields(); void setActiveTenantsUnboundedFields(String rxtConfig); void setTenantsUnboundedFields(Integer tenantId, Map<String, List<String>> rxtUnboundedFiledMap);  }### Answer:
@Test public void setActiveTenantsUnboundedFields() throws Exception { try { System.setProperty("carbon.home", ""); PrivilegedCarbonContext.startTenantFlow(); PrivilegedCarbonContext.getThreadLocalCarbonContext().setTenantId(-1234, true); RxtUnboundedFieldManagerService.getInstance().setActiveTenantsUnboundedFields(null); Map<Integer, Map<String, List<String>>> allTenantsUnboundedFields = RxtUnboundedFieldManagerService.getInstance ().getTenantsUnboundedFields(); assertNotNull(allTenantsUnboundedFields.get(-1234)); } finally { PrivilegedCarbonContext.endTenantFlow(); } }
