pls code for Junit testing in intellj

Add an Integer property called "DropLowestest"

if 0 then include all grades in this sum.

If set to "N" where N is > 0 - then drop the lowest 'N' score and make average use the other scores

If set to a Negative number then throw an exception

Change this method and write a proper set of tests to test it.

include in comments of EACH test

1-2 sentences that describe WHY you created it.

You have provided the full code, you need to provide the test scenarios in the class called EnrolledStudentTest.java, include new method (dropthelowestscore) and provide code for all your tests:
