NSubstitute 检查已接电话不起作用 [英] NSubstitute Checking received calls don't work

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.

Hey guys im new with the NSubstitute framework. I'm trying to test some of my classes, but when i use NSubstitute to check received calls it says received no matching calls.

我正在尝试测试 Tick() 方法是否正在从轨道类接收 update().

I'm trying to test if the method Tick() is receiving update() from track class.

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;
    private IRegion _region;
    private List<IEventDetection> _eventdetects;
    private List<IEvent> _events;

    public ATM()
    {
        _tracks = new List<ITrack>();
        _region = new Region.Region(100000,100000); //could be changed by user
        _events = new List<IEvent>();
        _eventdetects = new List<IEventDetection>();


    }



    public void Tick()
    {            

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

        //check for events
        foreach (var detector in _eventdetects)
        {
            _events.AddRange(detector.DetectEvent(_tracks));
        }

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

    }

    public void IncomingTrack(ITrack track)
    {
        //add incoming track
        _tracks.Add(track);
    }
}
}

        _track = Substitute.For<ITrack>();
        _event = Substitute.For<IEvent>();
        _eventDetection = Substitute.For<IEventDetection>();

        _uut = new ATM();
    }

    [Test]
    public void Tick_UpdateTracks_TracksUpdated()
    {
        _uut.Tick();
        _track.Received().update();
    }

}
}

推荐答案

您忘记在通知接收器中包含 _track.它只是没有订阅事件，因此没有得到通知.要修复只需调用您的 IncomingTrack 方法:

You forgot to include _track in notification receivers. It simply hasn't subscribed to event and as a result is not notified. To fix simply call your IncomingTrack method:

[Test]
public void Tick_UpdateTracks_TracksUpdated()
{
    _uut.IncomingTrack(_track);
    _uut.Tick();
    _track.Received().update();

}
