How to mock WCF client using Moq?

阅读更多关于 How to mock WCF client using Moq?

In my project I am using: SL5+ MVVM+ Prism + WCF + Rx + Moq + Silverlight Unit Testing Framework. I am new to unit-testing and have recently started into DI, Patterns (MVVM) etc. Hence the following code has a lot of scope for improvement (please fell free to reject the whole approach I am taking if you think so). To access my WCF services, I have created a factory class like below (again, it can be flawed, but please have a look): namespace SomeSolution { public class ServiceClientFactory:IServiceClientFactory { public CourseServiceClient GetCourseServiceClient() { var client = new

Mocking internal classes with Moq for unit testing

阅读更多关于 Mocking internal classes with Moq for unit testing

Both classes are internal. Correct me if I'm wrong but it looks like Moq can only mock a class if it is public, it has a public parameterless constructor, and the methods to be mocked are public virtual . I don't really want to make these classes publicly visible. Am I missing something with Moq, or is it just not suitable for what I want to do? I guess I could create an interface (say "IClassB") that ClassB implements,

I have a controller within MVC3 which needs to return a response code 500 if something goes wrong. I am doing this by returning a view object and setting http response code to equal 500 (I have checked this in firebug and all is working great). public ActionResult http500() { ControllerContext.HttpContext.Response.StatusCode = 500; ControllerContext.HttpContext.Response.StatusDescription = "An error occurred whilst processing your request."; return View(); } The problem I have now is I need to be able to write a unit test which checks the response code.
