### Question:
CpuOnlySplinePolynomialEnergyPredictor extends AbstractEnergyPredictor { @Override public void printFitInformation(Host host) { System.out.println(this.toString() + " - SSE: " + this.retrieveModel(host).getSumOfSquareError() + " RMSE: " + this.retrieveModel(host).getRootMeanSquareError()); } CpuOnlySplinePolynomialEnergyPredictor();  CpuOnlySplinePolynomialEnergyPredictor(PropertiesConfiguration config); @Override EnergyUsagePrediction getHostPredictedEnergy(Host host, Collection<VM> virtualMachines, TimePeriod duration); @Override EnergyUsagePrediction getVMPredictedEnergy(VM vm, Collection<VM> virtualMachines, Host host, TimePeriod timePeriod); EnergyUsagePrediction predictTotalEnergy(Host host, double usageCPU, 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 testPrintFitInformation() { System.out.println("printFitInformation"); setCalibrationData(host); host.setRamMb(32244); CpuOnlySplinePolynomialEnergyPredictor instance = new CpuOnlySplinePolynomialEnergyPredictor(); instance.printFitInformation(host); }
