c# - 使用最小起订量创建具有自动填充属性的模拟？

Question

我有一个我想模拟的对象(比如 HttpContext 或其他对象)。有时，在某些单元测试中，我不得不模拟大量依赖项，并适本地设置它们的依赖项和值。

下面有一些模拟 httpcontext 和另一个类的示例代码:

    public static HttpContextBase FakeHttpContext()
    {
        var context = new Mock<HttpContextBase>();
        var files = new Mock<HttpFileCollectionBase>();
        var request = new Mock<HttpRequestBase>();
        var response = new Mock<HttpResponseBase>();
        var session = new Mock<HttpSessionStateBase>();
        var server = new Mock<HttpServerUtilityBase>();
        var user = new Mock<IPrincipal>();
        var identity = new Mock<IIdentity>();
        request.Setup(req => req.ApplicationPath).Returns("~/");
        request.Setup(req => req.AppRelativeCurrentExecutionFilePath).Returns("~/");
        request.Setup(req => req.PathInfo).Returns(string.Empty);
        request.Setup(req => req.Form).Returns(new NameValueCollection());
        request.Setup(req => req.QueryString).Returns(new NameValueCollection());
        request.Setup(req => req.Files).Returns(files.Object);
        response.Setup(res => res.ApplyAppPathModifier(MoqIt.IsAny<string>())).
            Returns((string virtualPath) => virtualPath);
        user.Setup(usr => usr.Identity).Returns(identity.Object);
        identity.SetupGet(ident => ident.IsAuthenticated).Returns(true);

        context.Setup(ctx => ctx.Request).Returns(request.Object);
        context.Setup(ctx => ctx.Response).Returns(response.Object);
        context.Setup(ctx => ctx.Session).Returns(session.Object);
        context.Setup(ctx => ctx.Server).Returns(server.Object);
        context.Setup(ctx => ctx.User).Returns(user.Object);

        return context.Object;

        registrationView = new Mock<IRegistrationView>();
        registrationView.SetupGet(v => v.Address).Returns("Calle test");
        registrationView.SetupGet(v => v.EmailAddress).Returns("test@test.com");
        registrationView.SetupGet(v => v.Password).Returns("testpass");
        registrationView.SetupGet(v => v.FirstName).Returns("Name");
        registrationView.SetupGet(v => v.LastName).Returns("Surname");
        registrationView.SetupGet(v => v.DaytimePhoneNumber).Returns("666666666");
        registrationView.SetupGet(v => v.WholeSalers).Returns(new List<UserWholesaler>() { 
            new UserWholesaler(true) { CollaborationCode = "1234", Region = "TestReg", WholesalerCode = "10", WholesalerName = "TestWS", RegionName = "RegTest" } });

我想知道:是否有任何库，只要像“registrationView = new MockWithFilledProperties();”这样的调用，就可以让我创建一个 Mock，其属性填充了默认值？如果有，是哪一个？

谢谢你和亲切的问候。

Moq 允许您 stub 所有属性

registrationView.SetupAllProperties();

这将使所有属性跟踪它们的值(即您可以将一些值写入属性并稍后检索它)并将所有属性设置为其默认值。

注意:您可以使用链式模拟创建(又名规范查询)来更快地设置模拟

IRegistrationView view = Mock.Of<IRegistrationView>(ctx =>
    ctx.Address == "Calle test" &&
    ctx.EmailAddress == "test@test.com" &&
    ctx.Password == "testpass" &&
    ctx.FirstName == "Name" &&
    ctx.LastName == "Surname");
