Basically expectation is that while saving a budget we should have budget for all the expense categories and in case the user has not given budget for all the categories system before saving should add rest of the categories with zero amount and save.

In unit tests, sometimes you need to perform deep checks on the object passed to the mocked service. We will learn 3 ways to do that with Moq and C. In this article, we will learn 3 ways to check the values passed to the mocks when using Moq in our C Unit Tests. Rather, we are interested in checking that we are calling it with the right values. The simplest, most common way is by using It. In the example above, we used It. Notice that it accepts a parameter. This approach works well when you have to perform checks on only a few fields. But the more fields you add, the longer and messier that code becomes. Also, a problem with this approach is that if it fails, it becomes hard to understand which is the cause of the failure, because there is no indication of the specific field that did not match the expectations. The good parts of it are that you will gain more control over the assertions , and you will also have better error messages in case a test fails:. The bad part is that you will stuff your test class with lots of different methods, and the class can easily become hard to maintain. Unluckily, we cannot use local functions. On the other hand, having external functions allows us to combine them when we need to do some tests that can be reused across test cases.

It seems moq verify Verify call is designed to provide a nicer alternative to Strictso it would be nice to have that as well.

My goal in few specific tests is to verify that no unverified methods were called, for example:. I know I can do this with Strict , but I don't like how Strict affects the test structure and moves some expectations into the "Arrange" part of the test Setup.

This article is intended to explain the Verify , Setup and Callback features of the Moq unit testing framework with examples of how to use them. To have a piece of code to unit test, and also a dependency to mock I created a demo console app that will reverse a word and display it to the user. It uses the class WordUtils that has a dependency of UtilLogger the dependency we'll be mocking that's used to log a message to the console if this has been enabled in appsettings. You will also notice the word that's being reversed is stored in a simple cache a dictionary object ; this will be used to demonstrate the callback functionality. Before we jump into the verify, setup and callback features of Moq, we'll use the [TestInitialize] attribute in the MSTest framework to run a method before each test is executed. This method will define a mock of the IUtilLogger interface and initialize the class under test WordUtils. Now that we've got our mock created, let's write our first unit test to use the verification feature of Moq.

MockBehavior is an enum that specifies your created mocks behavior. This is an industry-standard and is a clean way to structure tests. Sorry for the confusion, I forgot that VerifyAll doesn't need it. For this syntax to work, verification would have to become an operation that changes state. BlythMeister - that would work just as well UserName ; Assert. VerifyNoOtherCalls actually make sense? LikesPizza, u. Are you sure you want to hide this comment? X AnyEvenInt ; mock. I'd be interested to hear what others think of this proposed feature. If not, does it mean MockBehavior.

Which is way easier to do if you just break on all exceptions and let the debugger take you there by just executing the test with a debugger attached ;. Fair enough, I guess this comes down to personal preferences in how you write your tests. We will learn 3 ways to do that with Moq and C. Calling mockRepository. In some tests, those mocks might be unnecessary, but, because of the VerifyAll call, we are forced to call them anyway. VerifyNoOtherCalls ; , then? For this reason, the sample class we will start from has several virtual methods:. Now that we have made these changes, we can access internal methods from the test assembly simply using the dot notation. This makes me feel warm inside. I personally would prefer the "VerifyNoOtherCalls" approach as a mocked interface whereby you expect a few things to be called would make the verifyany with never a bit cumbersome. AreEqual expected. Developers must own responsibility for their code and every change they make to the code. But in the end, that is probably also just a personal preference.
