我必须写自己的容器任务Linked_list和Array_list.我有一个接口:

typedef int value_type;
class Container 
{
public:
        class Iterator 
        {   
        public:
            Iterator();
            Iterator(value_type* other);
            Iterator(const Iterator& other);
            Iterator& operator=(const Iterator& other);
                    ...
        };

    Container();
    Container(const Container& other);
    ~Container();   

    virtual value_type& front() const=0;
    virtual value_type& back() const=0;
    virtual Iterator begin() const=0; // 
    ...
};

我做了派生类Linked_list和Array_list:

class Linked_list:public Container 
{
public:
    long int cur_size;
    List elem;
    static Link end_;
    class Iterator: public Container::Iterator
    {
        friend Linked_list;
        Link *p;    
    };

    Iterator begin() const; //overriding virtual function return type …

我需要为不是由我编写的小型学习计划编写测试(使用谷歌测试框架).(这只是一个小型控制台游戏,可以从命令行获取模式或只是在运行时获取它)有一个问题:我无法更改源代码,但几乎所有方法都使用cout和cin.我的问题是"如何在测试时回答programm的请求(cin)(比如从字符串获取cin的数据)？ ".

我有这个代码:

 Socket incomingConnection = serverSocket.accept();
 String strategy = "1";
 Client client = new Client(incomingConnection, this, strategy);

客户构造函数:

  public Client(Socket socket, ChatServer chatServer, String strategy) throws IOException{
        this.socket = socket;
        this.inputStream = socket.getInputStream();
        this.outputStream = socket.getOutputStream();

        this.chatServer = chatServer;
        this.instance1 = new Strategy1(chatServer, this);
        this.instance2 = new Strategy2(chatServer, this);
        this.strategy = (this.instance1.getName().equals(strategy1) ? this.instance1 : this.instance2);
        this.strategy.setStreams();
    }

现在看起来像Strategy1:

public class Strategy1{
public Strategy1(ChatServer server, Client client) throws IOException{
    this.chatServer = server;
    this.client = client;
}

public void …
