Consider the Java class Slice The objects of Slice are created with a weight.

public class Slice {

private double weight;

/**

postcondition: this.weight takes the absolute value
of weight. If weight is < 0.5 then this.weight takes
value 5.

public Slice(double weight) { this.weight = weight; if (weight < 0) {

this.weight = Math.abs(weight);

}

if (weight < 0.5){

this.weight = 0.5;

}

public double getWeight() {

return this.weight;

}

public double getPrice(double pricePG) {

/**

TODO
pricePG (price per gram) is >= 0 and
it goes in increments of 0.5. weight
is >= 0.5. Returns the price of the slice
as its weight multiplied by the

}

Class Slice offers a constructor method, a getter method for weight, and method getPrice that calculates the price of a slice. Assume you are developing a jUnit test for class Slice. Answer the questions below.

You wish to develop a fixture for method testSlice(), to test method Slice(). Say which objects you would create in the fixture, to ensure 100% decision coverage for Slice(). The number of objects you choose should be

minimal. Justify your answer.

Use equivalence class partitioning to define the set of states (i.e., fixture and input values for the parameter pricePG) for testing getPrice(). You need to show how you derived that state. Note that the code of getPrice() is not given because it is not necessary for the application of equivalence class partitioning. You can rely on the information in the code comments of method getPrice()

to answer this question.

Write a method testGetPrice() that tests getPrice(), checking that the returned price: (i) is positive, (ii) is calculated correctly. Note: use one (only one for simplicity) of the slice objects in the fixture and one of the values for pricePG you identified in your answer to b(ii). You can answer by building on the template

public void testCircumference() {
