### Question:
ExperimentManager { @Scheduled(fixedDelay = 15 * 1000) void updateExperimentStatus () { synchronized (allExperiments) { log.info("Experiments total count: {}", v("count", allExperiments.size())); if (!allExperiments.isEmpty()) { int experimentCount = Math.min(allExperiments.size(), 64); ForkJoinPool threadPool = null; try { threadPool = new ForkJoinPool(experimentCount); ForkJoinTask<?> threadPoolSubmit = threadPool.submit(this::evaluateExperiments); threadPoolSubmit.quietlyJoin(); } finally { if (threadPool != null) threadPool.shutdown(); } if (log.isDebugEnabled()) { printExperimentStats(); } allExperiments.removeIf(Experiment::isComplete); if (allExperiments.isEmpty()) { setLastExperimentComplete(); log.info("As of {}, there are no active experiments. The next experiment can run in {}.", lastExperimentComplete, experimentBackoffPeriod); } } } }  void setExperimentBackoffPeriod(Duration experimentBackoffPeriod); boolean areExperimentsInProgress();  }### Answer:
@Test public void updateExperimentStatus () { Experiment firstExperiment = mock(Experiment.class); Experiment secondExperiment = mock(Experiment.class); when(firstExperiment.getExperimentState()).thenReturn(CREATED); when(secondExperiment.getExperimentState()).thenReturn(CREATED); experimentManager.addExperiment(firstExperiment); experimentManager.addExperiment(secondExperiment); experimentManager.updateExperimentStatus(); verify(experimentManager).evaluateExperiments(); }
