I need to create some three cases using mockito framework to create stubs.

public class calculations {

// The following constants are used to indicate // the cost of coffee. public final double NO_COFFEE = 0.0; public final double REGULAR_COFFEE = 1.25; public final double DECAF_COFFEE = 1.25; public final double CAPPUCCINO = 2.00;

public final double WHITE_BAGEL = 1.25; public final double WHEAT_BAGEL = 1.50; // The following constants are used to indicate // the cost of toppings. public final double CREAM_CHEESE = 0.50; public final double BUTTER = 0.25; public final double PEACH_JELLY = 0.75; public final double BLUEBERRY_JAM = 0.75; private final double TAX_RATE = 0.06; // Sales tax rate public double getBagelCost(String bagleType) { double bagelCost = 0.0;

if (bagleType.equals("white")) bagelCost = WHITE_BAGEL; else bagelCost = WHEAT_BAGEL;

return bagelCost; } public double getCoffeeCost(int coffeeSelection) { double coffeeCost = 0.0;

if (coffeeSelection==1) coffeeCost = NO_COFFEE; else if (coffeeSelection==2) coffeeCost = REGULAR_COFFEE; else if (coffeeSelection==3) coffeeCost = DECAF_COFFEE; else coffeeCost = CAPPUCCINO;

return coffeeCost; } public double getToppingCost(boolean[] topping) { double toppingCost = 0.0;

if (topping[0]) toppingCost += CREAM_CHEESE; if (topping[1]) toppingCost += BUTTER; if (topping[2]) toppingCost += PEACH_JELLY; if (topping[3]) toppingCost += BLUEBERRY_JAM;

return toppingCost; } public double[] gettheBill(String bType, int cType, boolean[] toppings) { double bill[] = new double[5]; bill[0]= getCoffeeCost(cType); bill[1] = getBagelCost(bType); bill[2] = getToppingCost(toppings); bill[3] = (bill[0] + bill[1] + bill[3])* TAX_RATE; bill[4] = bill[0] + bill[1] + bill[2] + bill[3]; return bill; }

}
