Question

- Java Programming

- Develop JUnit test for a designated program

- Perform JUnit testing for on method that return both successful and unsuccessful results

- Create a JUnit test class for testing the getAverageScore and the getTotalScore methods.   On class per test.

public class Student
{
  
private String name;

private double totalScore;
  
private int quizCount;
  
public Student()
{
name = "";
totalScore = 0;
quizCount = 0;
}
n the name
*/
public Student(String n)
{
name = n;
totalScore = 0;
quizCount = 0;
}

public void setName(String aName)
{

name = aName;

}

public String getName()
{
return name;
}

public void addQuiz(int score)
{
if(score >= 0 && score <= 100)
{
totalScore = totalScore + score;
quizCount = quizCount + 1;
}
else
{
System.out.println("Score must be between 0 and 100, inclusive");
  
}
}

public double getTotalScore()
{
return totalScore;
}

public double getAverageScore()
{
return totalScore / quizCount;
}

}
