第一次和第二次使用Moq时返回值不同
第一次和第二次使用Moq时返回值不同
提问于 2011-09-03 02:07:42
我有一个这样的测试：
[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中运行了两次，我如何告诉Moq第一次返回null，第二次返回pageModel.Object？

添加一个回调函数对我不起作用，我使用这种方法代替了http://haacked.com/archive/2009/09/29/moq-sequences.aspx，我最终得到了一个这样的测试：
[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);

现有的答案很棒，但我想我应该加入我的替代方案，它只使用System.Collections.Generic.Queue，不需要任何模拟框架的特殊知识-因为我在编写它的时候没有任何知识！:)
var pageModel = new Mock<IPageModel>();
IPageModel pageModelNull = null;
var pageModels = new Queue<IPageModel>();
pageModels.Enqueue(pageModelNull);
pageModels.Enqueue(pageModel.Object);然后..。
repository.Setup(x => x.GetPageByUrl<IPageModel>(path)).Returns(pageModels.Dequeue);Stack Overflow用户

现在您可以使用SetupSequence了。参见this post。
var mock = new Mock<IFoo>();
mock.SetupSequence(f => f.GetCount())
.Returns(3) // will be returned on 1st invocation
.Returns(2) // will be returned on 2nd invocation
.Returns(1) // will be returned on 3rd invocation
.Returns(0) // will be returned on 4th invocation
.Throws(new InvalidOperationException()); // will be thrown on 5th invocation页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
