问题 I'm new C# and am trying to understand the new security features of .NET-4. To fill in some details, I'm currently trying to update AutofacContrib.Moq to work with the latest Moq. I had no problems doing this for .NET-3.5 and under. But in .NET-4 the security restrictions result in numerous security exceptions. Moq has a a single method, GetObjectData , that's marked with the SecurityCritical attribute. AutofacContrib.Moq has the AllowPartiallyTrustedCallers attribute set which is the source

Using Moq to mock an asynchronous method for a unit test

阅读更多关于 Using Moq to mock an asynchronous method for a unit test

I am testing a method for a service that makes a Web API call. Using a normal HttpClient works fine for unit tests if I also run the web service (located in another project in the solution) locally. However when I check in my changes the build server won't have access to the web service so the tests will fail. I've devised a way around this for my unit tests by creating an IHttpClient interface and implementing a version that I use in my application. For unit tests, I make a mocked version complete with a mocked asynchronous post method. Here's where I have run into problems. I want to return

问题 I have the following code: public interface IProductDataAccess { bool CreateProduct(Product newProduct); } Class ProductDataAccess implements that interface. public class ProductBusiness { public bool CreateProduct(Product newProduct) { IProductDataAccess pda = new ProductDataAccess(); bool result = pda.CreateProduct(newProduct); return result; } } In this case, how to create unit test for CreateProduct method by mocking the IProductDataAccess interface? I thought of having an public instance

问题 I have an action that relies on User.Identity.Name to get the username of the current user to get a list of his orders: public ActionResult XLineas() { ViewData["Filtre"] = _options.Filtre; ViewData["NomesPendents"] = _options.NomesPendents; return View(_repository.ObteLiniesPedido(User.Identity.Name,_options.Filtre,_options.NomesPendents)); } Now I'm trying to write unit tests for this, but I get stuck on how to provide a Mock for User.Identity.Name. If I run my test as I have it (without

Proper way to Mock repository objects for unit tests using Moq and Unity

问题 At my job we are using Moq for mocking and Unity for an IOC container. I am fairly new to this and do not have many resources at work to help me out with determining the best practices I should use. Right now, I have a group of repository interfaces (Ex: IRepository1, IRepository2... IRepository4) that a particular process needs to use to do its job. In the actual code I can determine all of the IRepository objects by using the IOC container and using the RegisterType() method. I am trying to

Unit test to verify that a base class method is called

阅读更多关于 Unit test to verify that a base class method is called

问题 I have a base class: public abstract class MyBaseClass { protected virtual void Method1() { } } and a derived class: public class MyDerivedClass : MyBaseClass { public void Method2() { base.Method1(); } } I want to write a unit test for Method2 to verify that it calls Method1 on the base class. I'm using Moq as my mocking library. Is this possible? I came across a related SO link: Mocking a base class method call with Moq in which the 2nd answer suggests it can be achieved by setting CallBase

I need to test the following method: CreateOutput(IWriter writer) { writer.Write(type); writer.Write(id); writer.Write(sender); // many more Write()s... } I've created a Moq'd IWriter and I want to ensure that the Write() methods are called in the right order. I have the following test code: var mockWriter = new Mock<IWriter>(MockBehavior.Strict); var sequence = new MockSequence(); mockWriter.InSequence(sequence).Setup(x => x.Write(expectedType)); mockWriter.InSequence(sequence).Setup(x => x.Write(expectedId)); mockWriter.InSequence(sequence).Setup(x => x.Write(expectedSender)); However, the

Mocking EF DbContext with Moq

I'm trying to create a unit test for my service with a mocked DbContext. I created an interface IDbContext with the following functions: public interface IDbContext : IDisposable { IDbSet<T> Set<T>() where T : class; DbEntityEntry<T> Entry<T>(T entity) where T : class; int SaveChanges(); } My real context implements this interface IDbContext and DbContext . Now I'm trying to mock the IDbSet<T> in the context, so it returns a List<User> instead. [TestMethod] public void TestGetAllUsers() { // Arrange var mock = new Mock<IDbContext>(); mock.Setup(x => x.Set<User>()) .Returns(new List<User> { new
