1.In Eclipse, write a test case in CalcTest for the multiply method of Calc

2 Include a screenshot of the CalcTest program with the new test case in the docx file

3.Modify the Calc program so the testAdd in CalcTest fails: Dont change the test case. Change the program Calc, imitating a situation where a programmer has introduced an error in the program

4. Include a screenshot of modified Calc program, and the screenshot of CalcTest failing in the docx file

package calcinclass; public class Calc \{ static public int add(int a, int b) return a+b; static public int multiply(int a, int b) return a
