Question

我的项目是一个机器人电报。我有一个名为Mainclass的类。我想测试它的方法（SubmitNewsGetType）。这个方法没有输入和输出。这个方法检查收到的消息来自用户并发送适当的回复。这是我对班级和方法的捍卫。

public class MainClass
{
    enum state : int
    {
        _firstState = 0,
        _submitNewsGetType = 1,
        _submitNewsGetNews = 11,
        _reservationGym = 2, 
        _reservationGymGetSans = 22, 
        _pollingForFood = 3, 
        _appointment = 4, 
        _cancelingReservation = 5, 
        _cancelingAppointment = 6, 
        Registeration = 7 
    };

    public TelegramBot bot;
    private  int stateBot;
    public Message sendMessage;
    private  string tempString;
    public  Message message;
    private  MessageTarget target;

    public void SubmitNewsGetType()
    {
        if (message.Text.Contains("/submitnews"))
        {
           sendMessage = bot.SendMessage(target, "Please select a type news: \n/Elmi\n/Farhangi\n/Honari\n/Amoozeshi\n/Varzeshi\n\n/Return");
        }
        else if (message.Text.Contains("/Elmi") ||
                 message.Text.Contains("/Farhangi") ||
                 message.Text.Contains("/Honari") ||
                 message.Text.Contains("/Amoozeshi") ||
                 message.Text.Contains("/Varzeshi"))
        {
           sendMessage = bot.SendMessage(target, "Please enter your news: \n\n/Return");

            stateBot = (int)state._submitNewsGetNews;
            tempString = message.Text;
        }
        else
        {
            bot.SendMessage(target, "Non definded! Please select a type news: \n/Elmi\n/Farhangi\n/Honari\n/Amoozeshi\n/Varzeshi\n\n/Return");
        }
    }

这是我的单元测试。我的问题是我无法初始化消息类型。

[TestMethod]
public void SubmitNewsGetNews_Test()
{
    MainClass instance = new MainClass();
    Message mess_output;

    //How to set value for a Message type??
    //This line get error
    Message mess_input="/submitnews"
    string expected="Please select a type news: \n/Elmi\n/Farhangi\n/Honari\n/Amoozeshi\n/Varzeshi\n\n/Return";

    if (mess_input is "/submitnews")
    {
        a.SubmitNewsGetType();
        mess_output= a.sendMessage;
        Assert.AreEqual(mess_output.Text,expected);
    } 
    else if (mess_input is "/elmi" or "/farhangi" or ...)
    else if ....
}

Answer 1

创建涵盖TelegramBot功能的界面，并让TelegramBot实现它。

interface ITelegramBot
{
    Message SendMessage(MessageTarget target, string msg);
}

将bot成员的类型更改为ITelegramBot

public ITelegramBot bot;

创建TelegramBot

class TelegramBotFake : ITelegramBot
{
    public Message ReturnMessage { get; set; }
    public string SendedMessage { get; set; }

    public Message SendMessage(MessageTarget target, string msg)
    {
        this.SendedMessage = msg;
        return this.ReturnMessage;
    }
}

测试。尽量使任何逻辑操作远离测试方法。任何逻辑都可能包含错误，测试方法中的错误很难发现为您的方法中的每个可能结果创建自己的测试 - 您将需要多于一个......

[TestMethod]
public void SubmitNewsGetNews_MessageContainsSubmitItems_SendPleaseSelectType()
{
    const string SUBMITITEMS = "/submitnews";
    TelegramBotFake fakebot = new TelegramBotFake();
    MainClass instance = new MainClass();
    instance.bot = fakebot; //Assign our fake bot
    instance.message.Text = SUBMITITEMS;
    string expected = "Please select a type news: \n/Elmi\n/Farhangi\n/Honari\n/Amoozeshi\n/Varzeshi\n\n/Return";

    instance.SubmitNewsGetType();

    //By checking faking bot.SendedMessage we sure that right method was executed
    Assert.AreEqual(instance.bot.SendedMessage, expected);
}

尝试将@NSManaged var weeks: Set<Week>更改为Message mess_input="/submitnews"您还错过了收到错误的一行的半冒号。
