使用XUnit测试动态expando

xunit.net caliburn.micro dynamic unit-testing c#

Erre Efe · 技术社区 · 7 年前

因此,我试图测试一个调用注入对话框API的方法(使用CaliburnMicro MVVM框架)。

方法

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

这就是我尝试测试它的方式:

测验

[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:

信息:Moq。MockException:“失败…”应在模拟上调用一次,但为0次: x => x.ShowDialog(It.IsAny<Screen>(), null, It.IsAny<Dictionary<String, Object>>())

配置的设置: x=>x、 ShowDialog(It.IsAny<Screen>(),null, 信息技术IsAny<词典(<字符串,对象(>)&燃气轮机;())

执行的调用:IWindowManager。ShowDialog(null,null, [[WindowsStartupLocation,CenterOwner],[ResizeMode,NoResize]])

我想这与我传递给 Is.Any 方法,但我不确定。有什么想法吗?

我认为您需要更换:

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

具有

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

在里面 Verify 呼叫因为 ExpandoObject 你路过这里 ShowDialog 机具 IDictionary 但事实并非如此 Dictionary 。

下面是我测试的代码:

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);
    }
}

您的代码在替换时失败 词典 具有 I词典 通过罚款:

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...");
