i would like some asistance, new to the software design i have an assignment due which involves junit coding: please help with the test class and assoicated junit code. thank you!

Unit being tested	Rule / requirement being tested	Setup work required	Test value	Expected result(s) (all must be verified via appropriate JUnit assert() invocations
createStudentCollection()	none default-sized collection	none	n/a	returned handle non-null; getCapacity() == DEFAULT COLLECTION_CAPACITY; isEmpty() == TRUE; isFull() == FALSE; getStudentCount() == 0; getRemainingSpaces() == DEFAULT COLLECTION_CAPACITY
createStudentCollection(int)	collection size > 0	none	-1	StudentCollectionException thrown
	"	"	0	StudentCollectionException thrown
	"	"	1	non-null handle returned; getCapacity() == 1; isEmpty() == TRUE; isFull() == FALSE; getStudentCount() == 0; getRemainingSpaces() ==1
getCapacity()	returns storage capacity
getSpacesRemaining()	returns number of available storage spaces
reset()	sets collection to an empty state
isFull()	determines if there is any remaining storage capacity
isEmpty()	determines if the collection is empty
getStudentCount()	returns number of elements in collection
addStudent()	inserts a student object into the collection	create collection of size 4; create student1 with a known SID value (SID1) (note replace "SID1" with a valid value during actual testing)	student1 instance	no exception thrown; getStudentCount() == 1; isEmpty() == false; isFull== false; getSpacesRemaining() == 3; retrieveStudentBySID(student1.getSID()) retrieves non-null handle and handle.getSID() == student1.getSID()
	"	using same collection, create student2 with SID2 (different from SID1)	student2 instance	no exception thrown; getStudentCount() == 2; isEmpty() == false; isFull() == false; getSpacesRemaining() == 2; retrieveStudentBySID(student2.getSID()) retrieves non-null handle and handle.getSID() == student2.getSID(); retrieveStudentBySID(student2.getSID()) retrieves non-null handle and handle.getSID() == student1.getSID() ("paranoia check")
	"	using same collection, create student3 with SID3 (different from SID1 and SID2)	student SID3 instance	no exception thrown; getStudentCount() == 3; isEmpty() == false; isFull() == true; getSpacesRemaining() == 1; retrieveStudentBySID(student3.getSID()) retrieves non-null handle and handle.getSID() == student3.getSID()

Here are the test classes in which need to be created
