addCourseName() – This method accepts a course code as a String.

subjectIllgibleToTeach-This returns a String with all the course codes an Instructor is certified to teach. The course codes should be separated by a comma but should not include [ ] at either end of the String. In other words, do not just return the ArrayList toString() method.


We have to pass the tests in both cases where tests are:

public void testAddCourseName()
    {
        String courseCode = "COMP1011";
        instructor.addCourseName(courseCode);
        assertEquals(courseCode, instructor.subjectIllgibleToTeach());
    }

and

public void testSubjectIllgibleToTeach()
    {
        String expResult = "COMP1011, COMP1008";
        instructor.addCourseName("COMP1011");
        instructor.addCourseName("COMP1008");
        String result = instructor.subjectIllgibleToTeach();
        assertEquals(expResult, result);
    }

We have to pass the certain tests and i have made a private arraylist of name courses above and passed string in it but still my test has been failing.

What I have tried:

if(courseCode.isEmpty())
              throw new IllegalArgumentException("Course code cannot be empty.");
        else
        courses.add(courseCode);
