### Question:
AveragePowerEnergyPredictor extends AbstractEnergyPredictor { @Override public double predictPowerUsed(Host host) { return getAverageHostPower(host, observationTime); } AveragePowerEnergyPredictor();  AveragePowerEnergyPredictor(PropertiesConfiguration config); @Override EnergyUsagePrediction getHostPredictedEnergy(Host host, Collection<VM> virtualMachines, TimePeriod duration); @Override EnergyUsagePrediction getVMPredictedEnergy(VM vm, Collection<VM> virtualMachines, Host host, TimePeriod timePeriod); @Override double predictPowerUsed(Host host); @Override double predictPowerUsed(Host host, double usageCPU); @Override double getSumOfSquareError(Host host); @Override double getRootMeanSquareError(Host host); @Override String toString(); @Override void printFitInformation(Host host);  }### Answer:
@Test public void testPredictPowerUsed_Host() { System.out.println("predictPowerUsed"); AveragePowerEnergyPredictor instance = new AveragePowerEnergyPredictor(); double result = instance.predictPowerUsed(host); assert (result >= 0.0); }
@Test public void testPredictPowerUsed_Host_double() { System.out.println("predictPowerUsed"); AveragePowerEnergyPredictor instance = new AveragePowerEnergyPredictor(); double result = instance.predictPowerUsed(host, 0.0); assert (result >= 0.0); }
