Question

因此，我正在尝试从注入的对话框API中测试方法（使用CaliburnMicro MVVM框架）。

方式

public bool? ShowDialog(Screen dialog)
{
    dynamic settings = new ExpandoObject();
    settings.WindowStartupLocation = WindowStartupLocation.CenterOwner;
    settings.ResizeMode = ResizeMode.NoResize;
    return _dialogAPI.ShowDialog(dialog, null, settings);
}

这就是我试图测试它的方式：

测试

[Fact]
public void DialogServiceCallAPIToShowDialog()
{
    var dialogAPI = new Mock<IWindowManager>();
    dialogAPI.Setup(x => x.ShowDialog(It.IsAny<Screen>(), null, It.IsAny<Dictionary<string, object>>())).Returns(() => true);

    var instance = new DialogService(dialogAPI.Object);
    instance.ShowDialog(It.IsAny<Screen>());

    dialogAPI.Verify(x => x.ShowDialog(It.IsAny<Screen>(), null, It.IsAny<Dictionary<string, object>>()), Times.Once, "Fail...");
}

问题

XUnit没有告诉我这个：

消息：Moq.MockException：＆＃34;失败...＆＃34;模拟上的预期调用   一次，但是0次：x => x.ShowDialog(It.IsAny<Screen>(), null, It.IsAny<Dictionary<String, Object>>())

已配置的设置：x => x.ShowDialog(It.IsAny<Screen>(), null, It.IsAny<Dictionary<String, Object>>())

执行调用：IWindowManager.ShowDialog（null，null，   [[WindowStartupLocation，CenterOwner]，[ResizeMode，NoResize]]）

我认为这与我传递给Is.Any方法的数据类型有关，但我不确定。有什么想法吗？

我认为你需要替换：

It.IsAny<IDictionary<string, object>>()

与

Verify

在ExpandoObject来电中

。由于您ShowDialog IDictionary传递了Dictionary，但public class Screen { } public interface IWindowManager { bool? ShowDialog(object rootModel, object context = null, IDictionary<string, object> settings = null); } public class DialogService { private IWindowManager _dialogAPI; public DialogService(IWindowManager dialogAPI) { _dialogAPI = dialogAPI; } public virtual bool? ShowDialog(Screen dialog) { dynamic settings = new ExpandoObject(); settings.WindowStartupLocation = WindowStartupLocation.CenterOwner; settings.ResizeMode = ResizeMode.NoResize; return _dialogAPI.ShowDialog(dialog, null, settings); } }不是Dictionary。

这是我测试过的代码：

IDictionary

您的代码失败了，而将var dialogAPI = new Mock<IWindowManager>(); dialogAPI.Setup(x => x.ShowDialog(It.IsAny<Screen>(), null, It.IsAny<Dictionary<string, object>>())).Returns(() => true); var instance = new DialogService(dialogAPI.Object); instance.ShowDialog(It.IsAny<Screen>()); dialogAPI.Verify(x => x.ShowDialog(It.IsAny<Screen>(), null, It.IsAny<IDictionary<string, object>>()), Times.Once, "Fail...");替换为{{1}}则传递正常：

{{1}}

使用XUnit测试动态expando
