【问题描述】：

大家好，我是 NSubstitute 框架的新手。我正在尝试测试我的一些课程，但是当我使用 NSubstitute 检查收到的电话时，它说没有收到匹配的电话。

我正在尝试测试 Tick() 方法是否从事件类接收 LogEvent() 和 HandleEvent(...)。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ATM_System.Event;
using ATM_System.EventDetection;
using ATM_System.Region;
using ATM_System.Track;

namespace ATM_System
{
public class ATM
{
    private List<ITrack> _tracks;//this list contains both Tracks and airpotrs
    private IRegion _region;
    private List<IEventDetection> _eventdetects;
    private List<IEvent> _events;



    public ATM(List<ITrack> airports, int region_size, List<IEventDetection> elist)
    //Sets airports, regionsize, and eventdetectors
    {
        _tracks = airports;
        _region = new Region.Region(region_size,region_size); 
        _events = new List<IEvent>();
        _eventdetects = elist;

    }

    public void Tick() //The tick function which is called each 250 ms
    {

        // update track positions
        foreach (var track1 in _tracks)
        {
            track1.update();
        }

        //check for events
        foreach (var detector in _eventdetects)
        {
            _events.AddRange(detector.DetectEvent(_tracks)); //this is simple: add the event list that the "detectevent" will 
                                                             //will return to the _events list
        }

        //handle events and output
        foreach (var event1 in _events)
        {
            event1.HandleEvent(_tracks);

            event1.LogEvent();
        }

    }

    public void Addairport(Airport AP)
    {
        _tracks.Add(AP);

    }

    public void IncomingTrack(ITrack track) //is called from main function when a new track is entering the region
    {
        //add incoming track
        _tracks.Add(track);
    }
}
}

【解决方案1】：

您正在尝试验证您的Tick 方法是否在IEvent 对象上调用HandleEvent 和LogEvent。

为此，您需要模拟 IEvent 并以某种方式将该模拟传递给您的 Tick 方法。

一种可能的方法（在您当前的设计中）是让您的_eventDetection 模拟返回在其DetectEvent 方法中表示IEvent 模拟。您保留对此模拟的引用并验证是否在其上调用了 HandleEvent 和 LogEvent。
