Example 1 with FlowLatencyMonitoringFsm

use of org.openkilda.wfm.topology.flowmonitoring.fsm.FlowLatencyMonitoringFsm in project open-kilda by telstra.

the class ActionServiceTest method shouldUpdateFlowInfo.

@Test

    long maxLatency = flow.getMaxLatency() / 2;
    long maxLatencyTier2 = flow.getMaxLatencyTier2() / 2;
    UpdateFlowCommand info = new UpdateFlowCommand(flow.getFlowId(), path, maxLatency, maxLatencyTier2);
    service.updateFlowInfo(info);
    assertEquals(2, service.fsms.values().size());
    FlowLatencyMonitoringFsm fsm = service.fsms.values().stream().findAny().orElseThrow(() -> new IllegalStateException("Fsm not found"));
    assertEquals(maxLatency, fsm.getMaxLatency());
