c# - 为什么 JustMock 声称我的模拟方法永远不会被调用？

Question

我的应用程序中有以下代码：

public class DirectoryCrawler
{
    private IPathWrap _path;
    private IDirectoryWrap _directory;
    private ITrackedFileStore _trackedFileStore;
    private IFileWrap _file;

    public DirectoryCrawler(IPathWrap path, ITrackedFileStore trackedFileStore, IDirectoryWrap directory, IFileWrap file)
    {
        _path = path;
        _trackedFileStore = trackedFileStore;
        _directory = directory;
        _file = file;
    }

    public void CheckDirectoryContents(string baseDirectory)
    {
        var trackedFiles = _trackedFileStore.GetTrackedFilesInPath(baseDirectory);
    }
}

我正在通过以下方式对其进行单元测试：

[TestClass]
public class DirectoryCrawlerTests
{
    private MockingContainer<DirectoryCrawler> _mockContainer;

    [TestInitialize]
    public void Setup()
    {
        _mockContainer = new MockingContainer<DirectoryCrawler>();
    }

    [TestMethod]
    public void Requests_Tracked_Files_In_Path()
    {
        var instance = _mockContainer.Instance;
        instance.CheckDirectoryContents("C:\\Test");

        _mockContainer.Assert<ITrackedFileStore>(x => x.GetTrackedFilesInPath(Arg.IsAny<string>()), Occurs.Once());
    }
}

但是，断言未能声称Result Message: Occurrence expectation failed. Expected exactly 1 call. Calls so far: 0

为什么 JustMock 没有正确检测到事件发生？这是最新的 JustMock lite Nuget 包 (2014.1.1317.4)

正如评论中所述，当您使用 AutoMocking 时，呼叫验证会有所不同。

您必须Arrange调用 automocked 依赖方法并使用MustBeCalled().
