问题 Given the following interface: public interface IFoo { bool Foo(string a, bool b = false); } Attempting to mock it using Moq: var mock = new Mock<IFoo>(); mock.Setup(mock => mock.Foo(It.IsAny<string>())).Returns(false); gives the following error at compile time: An expression tree may not contain a call or invocation that uses optional arguments I\'ve found the issue above raised as an enhancement in Moq\'s list of issues and it appears to be assigned to the 4.5 release (whenever that is). My

问题 Consider a method in a .NET assembly: public static string GetSecurityContextUserName() { //extract the username from request string sUser = HttpContext.Current.User.Identity.Name; //everything after the domain sUser = sUser.Substring(sUser.IndexOf(\"\\\\\") + 1).ToLower(); return sUser; } I\'d like to call this method from a unit test using the Moq framework. This assembly is part of a webforms solution. The unit test looks like this, but I am missing the Moq code. //arrange string ADAccount

问题 It is my understanding that I can test that a method call will occur if I call a higher level method, i.e.: public abstract class SomeClass() { public void SomeMehod() { SomeOtherMethod(); } internal abstract void SomeOtherMethod(); } I want to test that if I call SomeMethod() then I expect that SomeOtherMethod() will be called. Am I right in thinking this sort of test is available in a mocking framework? 回答1: You can see if a method in something you have mocked has been called by using

问题 i\'ve got an integration test that grabs some json result from a 3rd party server. It\'s really simple and works great. I was hoping to stop actually hitting this server and using Moq (or any Mocking library, like ninject, etc) to hijack and force the return result. is this possible? Here is some sample code :- public Foo GoGetSomeJsonForMePleaseKThxBai() { // prep stuff ... // Now get json please. HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(\"Http://some.fancypants.site

问题 I have a unit test fixture in which I\'m trying to test a ControllerAction on an ASP.NET MVC controller that\'s used for membership functions on a web app. I\'m trying to mock the HttpContext for the tests. The ControllerAction under test actually sets properties on the HttpContext, such as Session values, Response.Cookies values, etc. This isn\'t all of the code, but here is a rough sample of the test that I\'m trying to get to run: [Test] public void

问题 I\'ve got an interface which declares Task DoSomethingAsync(); I\'m using MoqFramework for my tests: [TestMethod()] public async Task MyAsyncTest() { Mock<ISomeInterface> mock = new Mock<ISomeInterface>(); mock.Setup(arg => arg.DoSomethingAsync()).Callback(() => { <my code here> }); ... } Then in my test I execute the code which invokes await DoSomethingAsync() . And the test just fails on that line. What am I doing wrong? 回答1: Your method doesn't have any callbacks so there is no reason to

问题 Recently, I\'ve begun to use Moq to unit test. I use Moq to mock out classes that I don\'t need to test. How do you typically deal with static methods? public void foo(string filePath) { File f = StaticClass.GetFile(filePath); } How could this static method, StaticClass.GetFile() get mocked? P.S. I\'d appreciate any reading materials you recommend on Moq and Unit Testing. 回答1: Mocking frameworks like Moq or Rhinomocks can only create mock instances of objects, this means mocking static

问题 I have been doing unit testing recently and I\'ve successfully mocked various scenarios using MOQ framework and MS Test. I know we can\'t test private methods but I want to know if we can mock static methods using MOQ. 回答1: Moq (and other DynamicProxy-based mocking frameworks) are unable to mock anything that is not a virtual or abstract method. Sealed/static classes/methods can only be faked with Profiler API based tools, like Typemock (commercial) or Microsoft Moles (free, known as Fakes in

问题 I\'m trying to create a unit test for a class that calls into an async repository. I\'m using ASP.NET Core and Entity Framework Core. My generic repository looks like this. public class EntityRepository<TEntity> : IEntityRepository<TEntity> where TEntity : class { private readonly SaasDispatcherDbContext _dbContext; private readonly DbSet<TEntity> _dbSet; public EntityRepository(SaasDispatcherDbContext dbContext) { _dbContext = dbContext; _dbSet = dbContext.Set<TEntity>(); } public virtual

问题 or can the class be implementing an abstract class also? 回答1: To mock a type, it must either be an interface (this is also called being pure virtual ) or have virtual members (abstract members are also virtual). By this definition, you can mock everything which is virtual . Essentially, dynamic mocks don't do anything you couldn't do by hand . Let's say you are programming against an interface such as this one: public interface IMyInterface { string Foo(string s); } You could manually create
