Test Plan for course grading software
Software to calculate and display grades for a high school course works as follows:

The software has a Student class with the following properties:

- student number (String)

- last name (String)

- first name (String)

- an array of scores on tests 1 through 10 (array of integers)

- final grade (double)

The Student class has constructors, get and set methods for each property, and the following:

- a method to let the teacher input a grade for a single test

- a method to calculate the final grade (an average of all 10 tests)

- a method to display a histogram (bar chart) of all 10 test scores grades for any student

The method that prints a histogram calls the histogram() method from the exisiting DataGraph Class which has been professionally validated.

All test score and the final grade are integers between 0 and 100 (0 <= n <= 100).
The main method for the software ties everything together. The class that contains the main method,

the Grading class, has an array of student objects and the following methods:

- a method with a menu for the teacher that calls other methods in the Grading class or Student class as needed. It also has an option to close the program

- a method that loads the array of Student objects from a data file

- a method to save the array of student objects to a data file

- a method to display results for any test or the final grade as a table, sorted by last name

- a method to display the grade distribution for any one test as a pie chart

The method that prints a pie chart calls the pieChart() method from the exisiting DataGraph Class which has been professionally validated.

Follow the outlined requirements. You should submit a word document with the testing plan.
