Tasks:

01) Create a JUnit test file called MyMathTest.java and a java file MyMath.java. In your JUnit test add the following four stub methods

• testAdd()
• testSubtract()
• testMultiply()
• testDivide()

In the regular java file add in the following stub methods

• int MyAdd(int a, int b)
• int MySubtract(int a, int b)
• int MyMultiply(int a, int b)
• int MyDivide(int a, int b)

02) Write five test cases for each of the unit test methods that call the appropriate methods in the java file. The unit tests should still fail at this point as you are writing the unit test first

03) Write the four methods in MyMath.java you may only move onto the next implementation once each unit test has been satisfied.
