Moq第一次和第二次返回值不同

本文介绍了Moq第一次和第二次返回值不同的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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 haacked/archive/2009/09/29/moq-sequences.aspx ，我最终进行了如下测试:

Adding a callback did not work for me, I used this approach instead haacked/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); }
