NSubstitute检查已接来电不起作用

嘿伙计们我是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。

我正在尝试测试方法Tick（）是否从track类接收update（）。

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 _tracks; private IRegion _region; private List _eventdetects; private List _events; public ATM() { _tracks = new List(); _region = new Region.Region(100000,100000); //could be changed by user _events = new List(); _eventdetects = new List(); } 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); } } } 

测试文件

 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.Track; using NUnit.Framework; using NSubstitute; namespace ATM_System.Tests.Unit { [TestFixture] class ATMUnitTests { private ATM _uut; private ITrack _track; private IEvent _event; private IEventDetection _eventDetection; [SetUp] public void Setup() { _track = Substitute.For(); _event = Substitute.For(); _eventDetection = Substitute.For(); _uut = new ATM(); } [Test] public void Tick_UpdateTracks_TracksUpdated() { _uut.Tick(); _track.Received().update(); } } } 

Answer 1

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：

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