Times, comes with a Never condition, so to make sure that a method never gets called, you would use this code: December 2018. I’ll keep the post for the sake of history. and this Moq setup. The Moq “Callback” method is what is needed to be able to make a change to an instance of a class that is passed in as a parameter. You can rate examples to help us improve the quality of examples. Moq doesn't have a NotVerify() method, instead, you can pass in a 'Times' enum as a second parameter into Verify() that specifies how many times the code should call that method. I'm using .NET 4.6.2 and Moq framework 4.2.1510.2205 (runtime version v4.0.20926). This issue is being caused by your GetDat method taking a ref parameter. 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'd check out Moq's Quickstart guide for more details, and the Matching Arguments section in particular. 18. Incidentally, if you need to you can get a reference to the method parameter by doing something like this: So what CAN we do? I suspect that (1) is an unsolvable problem given C#'s type system. It is possible to use both generic methods and wildcards in tandem. The first option is submit a patch to the Moq project. A powerful capability of Moq is to attach custom code to configured methods and properties' getters and setters. 4. With the latest version of Moq(4.2.1312.1622), you can setup a sequence of events using SetupSequence. Moq’s Setup, Verify, Verifiable and Callback Methods (The code here is C#) When trying to verify parameters passed to a method on a mocked object: Method 1: • Use Setup (which has taken the place of Expect) • Use It.Is(x => x == ExpectedParameter) In this example we will understand a few of the important setups of Moq framework.

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. One method of the mocked interface implementation is accepting a parameter of type Expression< Check calls Received() for async method. Moq Setup with Object Parameter This first unit test addresses my issue with the return value sql parameter above. Basically I am stuck with how to effectively unit test methods who are having Action delegate parameters. Ambiguous method call with Action parameter overload; 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?)

Here’s an example: ... has some useful overloads where you can return a value based on the parameters that were sent to the mocked method. In this article we will use Moq as our mocking framework.
