Question

l. Create a package in eclipse with the name cse360hw7. Copy the OrderedIntListjava file into this package. 2. Generate the initial set of JUnit test cases. All should have the default of fail. 3. Complete the code for your test cases. Create new methods as needed for the tests. Your tests should not have any if statements, loops or output. Use asserts to check the results. 4. Thoroughly test the code. Consider the following tests for insert. This is a minimum of 6 different tests. Each tests should be in its own method. a. insert into an empty list b. insert at beginning, at end and in middle c. insert duplicates d. insert causing array expansion 5. Make sure that all the code meets all coding and documentation standards. The junit test cases should include internal documentation while the orderedIntListjava file contain both internal and external documentation. 6. Submit the following file for grading OrderedIntListTestjava.

// You need to configure/add junit jar to eclipse
