### Question:
StraceDiagnosticManager { public List<MicroserviceStraceData> getMonitoringMicroservices() { return monitoringMicroservices; } private  StraceDiagnosticManager(); static StraceDiagnosticManager getInstance(); List<MicroserviceStraceData> getMonitoringMicroservices(); void updateMonitoringMicroservices(JsonObject diagnosticData); void enableMicroserviceStraceDiagnostics(String microserviceUuid); void disableMicroserviceStraceDiagnostics(String microserviceUuid);  }### Answer:
@Test public void testGetMonitoringMicroservices() { assertEquals(0, straceDiagnosticManager.getMonitoringMicroservices().size()); microserviceStraceData = new MicroserviceStraceData(microserviceUuid, 5, true); straceDiagnosticManager.getMonitoringMicroservices().add(microserviceStraceData); assertEquals(1, straceDiagnosticManager.getMonitoringMicroservices().size()); }
