can you help me how to test this 

Part 1: Test Program

Write a program to test all test cases outlined in the test plan. For each method (unit) being tested, ensure your client program provides output clearly describing the method being tested along with the expected and actual result.

  • When testing constructors, verify the results by calling an accessor method of the class.
  • When testing mutators, use the accessor method to verify the state change.
  • When a test fails (actual does not match the expected), correct the method code, then re-test.  Keep in mind that a poorly written test can produce inaccurate test results.  If a test fails, ensure you have written the test correctly before modifying your unit code.
Output Requirement

For each method (unit), output the method signature.

For each test, output the following:

  • Test number
  • Outcome description
  • Expected result
  • Actual result

Leave one blank line between each test.

Sample
StudentGrades(int) Test #1 - Initialize grades array without data. Expected: [0, 0, 0, 0] Actual: [0, 0, 0, 0]

 

Unit StudentGrades(int) StudentGrades(int[]) getGrades(): int[] setGrades(int[]): void A getSortedGrades[] : int[] getHighestGrade(): int getAverageGrade(): double toString(): String B Total Tests: 7 # 1 1 1 1 1 1 1 Module 6 Assignment - Test Plan Outcome Initialize grades array without data. Initialize grades array with Return a copy of the grades array sorted in ascending Update the state of the grades. Initial grades = ? grades? Return the correct highest grade value Return the correct average of all the grades. Test Data numberOfStudents ? Return the correct String representation. grades? grades ? = grades 7 grades? grades Expected ? ? ? ? ? ? ? E Comments Use getGrades() to verify. Use getGrades() to verify. Tested above. Use getGrades() to verify. Start your Expected input with a single quote ('). Use alt-enter for a line break in the expected data. G
