CSC 217 Lab 08 - Update Schedule and Student

CSC 217 Lab 08 Update `RegistrationManager`

RegistrationManger will handle the new enroll and drop functionality at a global level. When a student tries to enroll in a course, they must be able to add the Course to their Schedule and the Student must be added to the Course’s CourseRoll. This requires several checks before a student can be enrolled or dropped.

Due to the complicated logic, the teaching staff has provided the implementation and unit tests for the RegistrationManager functionality. Updates to the GUI classes are also required.

Update `RegistrationManager`

Add the following three methods to RegistrationManager.

/**
 * Returns true if the logged in student can enroll in the given course.
 * @param c Course to enroll in
 * @return true if enrolled
 */
public boolean enrollStudentInCourse(Course c) {
    if (currentUser == null || !(currentUser instanceof Student)) {
        throw new IllegalArgumentException("Illegal Action");
    }
    try {
        Student s = (Student)currentUser;
        Schedule schedule = s.getSchedule();
        CourseRoll roll = c.getCourseRoll();
        
        if (s.canAdd(c) && roll.canEnroll(s)) {
            schedule.addCourseToSchedule(c);
            roll.enroll(s);
            return true;
        }
        
    } catch (IllegalArgumentException e) {
        return false;
    }
    return false;
}

/**
 * Returns true if the logged in student can drop the given course.
 * @param c Course to drop
 * @return true if dropped
 */
public boolean dropStudentFromCourse(Course c) {
    if (currentUser == null || !(currentUser instanceof Student)) {
        throw new IllegalArgumentException("Illegal Action");
    }
    try {
        Student s = (Student)currentUser;
        c.getCourseRoll().drop(s);
        return s.getSchedule().removeCourseFromSchedule(c);
    } catch (IllegalArgumentException e) {
        return false; 
    }
}

/**
 * Resets the logged in student's schedule by dropping them
 * from every course and then resetting the schedule.
 */
public void resetSchedule() {
    if (currentUser == null || !(currentUser instanceof Student)) {
        throw new IllegalArgumentException("Illegal Action");
    }
    try {
        Student s = (Student)currentUser;
        Schedule schedule = s.getSchedule();
        String [][] scheduleArray = schedule.getScheduledCourses();
        for (int i = 0; i < scheduleArray.length; i++) {
            Course c = courseCatalog.getCourseFromCatalog(scheduleArray[i][0], scheduleArray[i][1]);
            c.getCourseRoll().drop(s);
        }
        schedule.resetSchedule();
    } catch (IllegalArgumentException e) {
        //do nothing 
    }
}

Update `RegistrationManagerTest`

Update the fields and setUp() method for RegistrationManagerTest. This will read the properties file for the registrar username and password and set them to fields for use in the new tests.

	/** Instance for RegistrationManager */
	private RegistrationManager manager;
	/** Registrar user name */
	private String registrarUsername;
	/** Registrar password */
	private String registrarPassword;
	/** Properties file */
	private static final String PROP_FILE = "registrar.properties";
	
	/**
	 * Sets up the CourseManager and clears the data.
	 * @throws Exception if error
	 */
	@Before
	public void setUp() throws Exception {
		manager = RegistrationManager.getInstance();
		manager.logout();
		manager.clearData();
		
		Properties prop = new Properties();
		
		try (InputStream input = new FileInputStream(PROP_FILE)) {
			prop.load(input);
			
			registrarUsername = prop.getProperty("id");
			registrarPassword = prop.getProperty("pw");
		} catch (IOException e) {
			throw new IllegalArgumentException("Cannot process properties file.");
		}
	}

Then, add the following three test methods to RegistrationManagerTest. Note that the leading strings describe the tests.

	/**
	 * Tests RegistrationManager.enrollStudentInCourse()
	 */
	@Test
	public void testEnrollStudentInCourse() {
		StudentDirectory directory = manager.getStudentDirectory();
		directory.loadStudentsFromFile("test-files/student_records.txt");
		
		CourseCatalog catalog = manager.getCourseCatalog();

		manager.logout(); //In case not handled elsewhere

			fail("RegistrationManager.enrollStudentInCourse() - If the current user is null, an IllegalArgumentException should be thrown, but was not.");
		} catch (IllegalArgumentException e) {

		}
		
		//test if registrar is logged in
