How to create a test class in java? Please Help!

I need to create both a recipe class, as well as a recipe test class. I have created the recipe class, but I am not sure what I am supposed to do with the provided test code. Is this something I create in my existing program below my recipe class? or is this a whole new program I create and then somehow import the recipe class into it? Very confused!

These are the instructions I am provided with:

*To test the functionality of your finished code, use the SteppingStone5_RecipeTest.java file

*Replace the public static void main(String[] args) with public SteppingStone5_Recipe createNewRecipe()

This is my recipe class code, and below that is what I have for the test code. Thanks in advance for any help! :

package steppingstone5_recipe;

/**

//Imported classes

import java.util.Scanner;

import java.util.ArrayList;

public class SteppingStone5_Recipe {

// Declared the variables

private String recipeName;

private double totalRecipeCalories;

private ArrayList recipeIngredients;

private int servings;

// Created a default constructor.

public SteppingStone5_Recipe()

{

this.recipeName = "";

this.servings = 1; //<--- assigned value with data type

this.recipeIngredients = new ArrayList(); //<-- assigned value for ArrayList

this.totalRecipeCalories = 0;

}

public SteppingStone5_Recipe(String recipeName, int servings,

ArrayList recipeIngredients, int totalRecipeCalories) //Added data type for the ArrayList and the servings arguments

{

this.recipeName = recipeName;

this.servings = servings;

this.recipeIngredients = recipeIngredients;

this.totalRecipeCalories = totalRecipeCalories;

}

//This will print the recipe once user types "end" after ingredients are entered.

public void printRecipe() {

float singleServingCalories = (float) getTotalRecipeCalories() / getServings();

System.out.println(" Recipe: " + getRecipeName());

System.out.println("Serves: " + getServings());

System.out.println("Ingredients:");

for (int i = 0; i < getRecipeIngredients().size(); i++) {

System.out.println("\t" + getRecipeIngredients().get(i));

}

System.out.println("Each serving has " + singleServingCalories + " Calories.");

}

//Main Method

public static void main(String[] args) {

//corrected data type & Scanner assignment method for servings

int servings = scnr.nextInt();

do {

System.out.println("Please enter the ingredient name"

+ " or type end if you are finished entering ingredients: ");

String ingredientName = scnr.next();

if (ingredientName.toLowerCase().equals("end")) {

addMoreIngredients = false;

} else {

//Adds the ingredient name to recipeIngredients

recipeIngredients.add(ingredientName);

System.out.println("Please enter the ingredient amount (Cups): ");

int ingredientCalories = scnr.nextInt();

/**

totalRecipeCalories += ingredientCalories * ingredientAmount;
