问题 Going thru https://github.com/Moq/moq4/wiki/Quickstart, I see it Mock an interface. I have a class in my legacy code which does not have an interface, when I `Mock' , I get the following exception: Additional information: Can not instantiate proxy of class: MyCompnay.Mylegacy.MyClass. How can I use Moq to mock class from Legacy code? Thank you. 回答1: It is possible to Mock concrete classes [TestClass] public class PlaceholderParserFixture { public class Foo { public virtual int GetValue() {

关于单元测试的思考--Asp.Net Core单元测试最佳实践

由 删除回忆录丶 提交于 2020-05-06 09:13:18
在我们码字过程中，单元测试是必不可少的。但在从业过程中，很多开发者却对单元测试望而却步。有些时候并不是不想写，而是常常会碰到下面这些问题，让开发者放下了码字的脚步： 这个类初始数据太麻烦，你看：new MyService(new User("test",1), new MyDAO(new Connection(......)),new ToManyPropsClass(......) .....) 。我：。。。 这个代码内部逻辑都是和Cookie有关，我单元测试不好整啊，还是得启动到浏览器里一个按钮一个按钮点。 这个代码内部读了配置文件，单元测试也不能给我整个配置文件啊？ 这个代码主要是验证WebAPI入口得模型绑定，必须得调用一次啊？ 这些问题确实存在，但它们阻止不了我们那颗要写单元测试的心。单元测试的优点很多，你或许可以不管。但至少能让你从那些需要在浏览器里点击10多下的操作里解脱出来。 本文从一个简单的逻辑测试出发，慢慢拉开测试的大幕，让你爱上测试。文章主要是传播一些单元测试的理念，其次才是介绍asp.net core中的单元测试。 本文使用的环境为asp.net core 2.1 webapi，代码可以直接下载: https://github.com/yubaolee/DotNetCoreUnitTestSamples 为了方便阅读，以一个最简单的逻辑为例： public

When should I use the .As method of Moq?

由 别说谁变了你拦得住时间么 提交于 2020-04-29 15:43:09
问题 When exactly do we need to use the .As method provided by Moq? From the Quickstart documentation: // implementing multiple interfaces in mock var foo = new Mock<IFoo>(); var disposableFoo = foo.As<IDisposable>(); // now the IFoo mock also implements IDisposable :) disposableFoo.Setup(df => df.Dispose()); But I just don't get why we would want to do that. Could you give me a practical example? 回答1: Okay, so an example. Let's say you have a transportation management software to manage movement

问题 This question already has answers here : Expression references a method that does not belong to the mocked object (4 answers) Closed 2 years ago . I have used IConfigurationRoute to access a directory like this. if (type == "error") directory = _config.GetValue<string>("Directories:SomeDirectory"); _config is IConfigurationRoot injected in the constructor. I tried the following way to mock it. var mockConfigurationRoot = new Mock<IConfigurationRoot>(); mockConfigurationRoot.Setup(c => c
