Beans with CreateImmediately or which implement IPlatformListener [message #1858121] Thu, 16 March 2023 12:53 Go to next message

we are using LookupCalls/LookupServices, which query our ERP system via REST. Since the response from the erp is rather slow and the data doesn't change often, we implemented a simple caching mechanism.

In order to schedule a refresh job I annoted the LooupService with @CreateImmediately. Unfortunately the Service gets created during the unit test run too. I tried, not to use @CreateImmediately and let the LookupService implement IPlatformListener. But the Platform is startet during the tests, too.
So this is the "solution" I've come up with. Is there a better way to check if the application is in "normal" and not in testing mode? Or is there another way to achieve what I am trying to do?

public abstract class SimpleCachingLookupService<ID> implements ILookupService<ID>, IPlatformListener {

  private IFuture refreshFuture = null;
  public SimpleCachingLookupService(boolean enableScheduledRefresh) {
    this.scheduledRefreshEnabled = enableScheduledRefresh;

  public void stateChanged(PlatformEvent event) {
    if (isScheduledRefreshEnabled() &&
      event.getState() == IPlatform.State.PlatformStarted &&
      refreshFuture == null
      && !"GlobalTestingPlatform".equals(event.getSource().getClass().getSimpleName())
    ) {
    if (isScheduledRefreshEnabled() &&
      event.getState() == IPlatform.State.PlatformStopping &&
      refreshFuture != null &&
    ) {
  private void addScheduledRefreshJob() {
    if (isScheduledRefreshEnabled()) {
      refreshFuture = Jobs.schedule(() -> {
          if (RunMonitor.CURRENT.get().isCancelled()) {
  "Job {} is cancelled", IFuture.CURRENT.get().getJobInput().getName());
          .withName(String.format("SimpleCachingLookupService(%s) Refresh Job", this.getClass().getSimpleName()))
              .repeatForever())));"Scheduled {}, interval {} s", refreshFuture.getJobInput().getName(), getCacheTimeout());
  /* ... */

Hi Nils

You could use a config property to enable/disable your job, implement the config property as default value true and override it in your file of your test case to false.

Another solution would be to implement your REST service as Scout Bean with a default implementation in your production code and a second Mock-Implementation in your testcode, using a lower @Order(value) annotation in order to force the test environment to use the mocked implementation.
Benefit of the second solution is, that your lookup caching could also be unit tested against the mocked REST client implementation.
