Question

在我的应用程序中，我有两个名为Platform和另一个Organizer的类。

平台类

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class Platform {
private List<User> users;
private List<Competition> competitions;

public Platform() {
    /**
     * PR1 Ex 2.1: We need to initialize the list of users
    */
    users = new ArrayList<User>();
}

User findUser(String username) { 
    /**
     * PR1 Ex 2.1: Implementation of method findUser to find a user in the list users by username
    */
    User user = null;

    Iterator<User> itr = this.users.iterator();      
    while(itr.hasNext() && user == null) {
        User u = itr.next();
        if(u.getUserName().equals(username)) {
            user = u;
        }
    }

    return user;
}

public User registerUser(String username, String password, String fullname) {        
    /**
     * PR1 Ex 2.1: Register a new user, checking that it does not exist 
    */
    User newUser = null;

    // Check if the user is new or already exists
    User queryUser = findUser(username);

    if(queryUser==null) {
        newUser = new User(this, username, password, fullname);
        this.users.add(newUser);
    }

    return newUser;
}

public User login(String username, String password) {    
    /**
     * PR1 Ex 2.2: Login an already existing user
    */
    User user = null;

    // Find the user in the list of registered users
    User queryUser = findUser(username);        

    // If the user exists, check the password
    if(queryUser!=null && queryUser.checkPassword(password)) {
        user = queryUser;
    }

    return user;        
}    

public Integer getNumUsers() {
    /**
     * PR1 Ex 2.1: Required for test, to check if a new user is registered 
    */
    return this.users.size();
}

public Integer getNumCompetitions() {        
    return null;
}

public Message sendMessage(User from, String to, String subject, String message) throws CompetitionException {               
    User receiver = findUser(to);
if (to == null) {
    throw new CompetitionException(CompetitionException.SENDER_NOT_FOUND);
}
else if(receiver == null ) {
    throw new CompetitionException(CompetitionException.SENDER_NOT_FOUND); //Aquí debes lanza el tipo de excepción apropiado de tu lógica de negocio
}
Message  m = new Message(this, this, subject, message);
return m;
}
public void registerCompetition(Competition competition) {

}    

public List<Competition> getOpenCompetitions() {        
    return null;
}

private void evaluateAll() {

}

public void run() {
    // Simulates system call for evaluation
    evaluateAll();
  }
 }

和课程组织者

import java.util.ArrayList;
import java.util.List;

public class Organizer extends User {
private List<Competition> competitions;

public Organizer(User user) {
    super(user);
    // Initialize the list of competitions
    competitions = new ArrayList<Competition>();                
}

public void removeSubmission(Submission submission) {
    /* NOT IMPLEMENTED */
}

public boolean sendMessage(Competition competition, String subject, String message) {
    /* NOT IMPLEMENTED */
    return false;
}

public Competition newCompetition(String title, float target) {        
   Competition s =new Competition(platform, this, title, target);
}

public void closeCompetition(Competition competition) {

}

public List<Competition> getCompetitions() {        
    return this.competitions;
}

private void updateCompetitions() {

 }
}

我想实现Organizer类的newCompetition方法，以便它通过a的参数提供数据新竞争：

- 为新比赛实例化一个对象，然后使用registerCompetition在平台上注册比赛

类Organizer newCompetition的方法我有它

  public Competition newCompetition(String title, float target) {        
   Competition s =new Competition(platform, this, title, target);
   competitions.add(s);
   return s;
}

如何使用平台的registerCompetition方法注册竞赛？

我有以下类测试，我想知道如何实现这些方法来传递它们

班级考试

public class PR2_Ex2_1_Test {

private final String username1 = "username1";
private final String password1 = "password1";
private final String fullName1 = "Test User 1";

private final String username2 = "username2";
private final String password2 = "password2";
private final String fullName2 = "Test User 2";

private final String comp_title1 = "Approximate number PI";
private final float comp_target1 = 3.141592653589793238f;

private Platform platform = null;
private User u1 = null;    
private User u2 = null;    

public PR2_Ex2_1_Test() {        
}

@BeforeClass
public static void setUpClass() {

}

@AfterClass
public static void tearDownClass() {
}

@Before
public void setUp() {
    // Create the test scenario
    platform = new Platform();

    // Register new users
    u1 = platform.registerUser(username1, password1, fullName1); 
    u2 = platform.registerUser(username2, password2, fullName2);
}

@After
public void tearDown() {

}  

@Test
public void createCompetitionObject() {   
    Organizer o1 = u1.asOrganizer();

    Competition c1 = o1.newCompetition(comp_title1, comp_target1);

    assertNotNull(c1);
    assertEquals(o1, c1.getOwner());        
    assertTrue(c1.isOpen()); 
    assertNotNull(c1.getSubmissions());
    assertEquals(0, c1.getSubmissions().size());
}

@Test
public void duplicatedCompetitionObjects() {   
    Organizer o1 = u1.asOrganizer();        
    Competition c1 = o1.newCompetition(comp_title1, comp_target1);
    Competition c2 = o1.newCompetition(comp_title1, comp_target1);

    // If id is correct, they cannot be equals
    assertThat(c1, is(not(equalTo(c2))));

    // Id cannot depend on the owner
    Organizer o2 = u2.asOrganizer();   
    Competition c3 = o2.newCompetition(comp_title1, comp_target1);               
    assertThat(c1, is(not(equalTo(c3))));        
}

@Test
public void AssociatedObjects() {   
    Organizer o1 = u1.asOrganizer();        
    Competition c1 = o1.newCompetition(comp_title1, comp_target1);       

    assertEquals(new Integer(1), platform.getNumCompetitions());
    assertEquals(1, o1.getCompetitions().size());
  }
}

实施两种方法
