Moq第一次和第二次返回值不同 [英] Different return values the first and second time with Moq

问题描述

我有这样的测试:

    [TestCase("~/page/myaction")]
    public void Page_With_Custom_Action(string path) {
        // Arrange
        var pathData = new Mock<IPathData>();
        var pageModel = new Mock<IPageModel>();
        var repository = new Mock<IPageRepository>();
        var mapper = new Mock<IControllerMapper>();
        var container = new Mock<IContainer>();

        container.Setup(x => x.GetInstance<IPageRepository>()).Returns(repository.Object);

        repository.Setup(x => x.GetPageByUrl<IPageModel>(path)).Returns(() => pageModel.Object);

        pathData.Setup(x => x.Action).Returns("myaction");
        pathData.Setup(x => x.Controller).Returns("page");

        var resolver = new DashboardPathResolver(pathData.Object, repository.Object, mapper.Object, container.Object);

        // Act
        var data = resolver.ResolvePath(path);

        // Assert
        Assert.NotNull(data);
        Assert.AreEqual("myaction", data.Action);
        Assert.AreEqual("page", data.Controller);
    }

GetPageByUrl在我的dashboardpathresolver中运行两次，如何告诉Moq第一次返回null，第二次返回pageModel.

GetPageByUrl runs twice in my dashboardpathresolver, how can I tell Moq to return null the first time and pageModel.Ojbect the second?

推荐答案

添加回调对我不起作用，我改用这种方法

Adding a callback did not work for me, I used this approach instead http://haacked.com/archive/2009/09/29/moq-sequences.aspx and I ended up with a test like this:

    [TestCase("~/page/myaction")]
    [TestCase("~/page/myaction/")]
    public void Page_With_Custom_Action(string virtualUrl) {

        // Arrange
        var pathData = new Mock<IPathData>();
        var pageModel = new Mock<IPageModel>();
        var repository = new Mock<IPageRepository>();
        var mapper = new Mock<IControllerMapper>();
        var container = new Mock<IContainer>();

        container.Setup(x => x.GetInstance<IPageRepository>()).Returns(repository.Object);
        repository.Setup(x => x.GetPageByUrl<IPageModel>(virtualUrl)).ReturnsInOrder(null, pageModel.Object);

        pathData.Setup(x => x.Action).Returns("myaction");
        pathData.Setup(x => x.Controller).Returns("page");

        var resolver = new DashboardPathResolver(pathData.Object, repository.Object, mapper.Object, container.Object);

        // Act
        var data = resolver.ResolvePath(virtualUrl);

        // Assert
        Assert.NotNull(data);
        Assert.AreEqual("myaction", data.Action);
        Assert.AreEqual("page", data.Controller);
    }
