Callback (() = > TestContext. A powerful capability of Moq is to attach custom code to configured methods and properties' getters and setters. The following two lines override that behavior for specific values. Basically I am stuck with how to effectively unit test methods who are having Action delegate parameters.

Using Delegates In C#, a delegate is a function signature that can be passed around as a parameter. IsAny < int > ())). For most of my tests, I like to use Moq, the .NET mocking library that allows you to mock objects and services.It's one of the best libraries for complementing and supporting unit tests. This is described in the official QuickStart document of Moq. In this article we will use Moq as our mocking framework. Incidentally, if you need to you can get a reference to the method parameter by doing something like this: Hi, everyone. Please notice that getter methods have no parameters while setter methods have a single parameter of the type of the property. Spending my days writing lots of unit tests lately...You know the drill. What I need is just to add: Assuming that there were a solution for (1), you'd now have to get the TDelegate parameter gathered at Setup to Returns (which is a separate method call). I used the Moq framework, and when I set up the method in question, I defaulted the optional parameters. this.mockRepository .Setup(mr => mr.GetStuff(It.IsAny())) .Returns((int id) => SomeFunctionThatReturnsStuff(id)); One other method I saw on a blog some time back (Phil Haack perhaps?)

This was required, as leaving them out of the Setup() call was not allowed. (2) I believe your only choice right now is to explicitly include the bool parameter in the setup … This ensures that the flow of the program is as expected. In this case we are able to call the Submit() method on the dialog view-model automatically when the mocked ShowChromelessDialog method is called (see lines 10 and 11). We would like to make sure that the object's created and updated time should be set with current time.
